Software testing is a technique to validate websites or mobile applications, identify bugs or issues, and ensure they work as intended. This process is a critical part of the Software Development Life Cycle. Being a continuous and systematic process, it allows for the verification of the alignment of software applications with their Software Requirement Specification (SRS), validates their functionality, and ensures their reliability and seamless user experience.

According to a recent Consortium for Information and Software Quality report, software applications that lack quality cost US organizations $2.08 trillion annually. One of the reasons was software bugs, and thus, there is a great demand for robust, error-free software, which put software testing at the forefront of the development process.

However, there is not just one type of software testing to efficiently test the different components of software applications at various phases of the software development process. Based on the diverse requirements and purposes, there are different types of software testing.

Each type of software testing serves a unique purpose, from unit and integration to performance and user acceptance testing. Understanding the significance of these diverse types of software testing is imperative for developers and testers.

This article will discuss various types of software testing and include them in one accessible resource for easy learning. So, let us get started.

What is Software Testing?

Software testing is the process of ensuring that software applications are functional, reliable, and of high quality. This process involves finding errors and vulnerabilities to ensure the software application meets the user’s expectations before going live.

It analyzes the software application’s characteristics to identify missing requirements, bugs, or errors and its reliability, security, and performance. As a result, the primary objective is to ensure that the software application meets the specified requirements, is reliable, functional, and performs as expected.

Testers perform software testing through manual or automation techniques to ensure the software application functions as intended. This involves careful planning, test case creation, running of test script, and debugging, etc. Following tests, testers communicate results to the development team for further modifications, aiming to deliver a high-quality software application to the users.

It is an essential part of the Software Development Life Cycle (SDLC) and provides necessary mitigation against possibly business-impacting bugs that would otherwise go undetected.

Importance of Software Testing

Testing software applications has always been critical in software development, and the importance of quality control cannot be overstated. Delays or defects in software applications can harm an organization’s reputation, resulting in customer dissatisfaction and loss. In more severe cases, a bug or defect can jeopardize interconnected applications or cause major malfunctions.

To better understand the importance of software testing, let’s see the real-world examples that have caused significant issues. Think about Nissan having to recall over 1 million cars due to a software defect in airbag sensor detectors or a software bug causing the failure of a USD 1.2 billion military satellite launch.
While testing incurs expenses, organizations can save millions annually in development and support by implementing effective testing methodologies and robust QA processes.

Early software testing is critical for identifying issues before a product hits the market. The sooner development teams receive test feedback, the faster they can address issues such as architectural shortcomings, inadequate design decisions, void functionality, security vulnerabilities, and scalability.

Similarly, reputable organizations have to safeguard their user base and credibility by providing flawless software applications to end users. Let’s look at specific points to see why software testing is still necessary in software development.

Detecting defects early in the development process is critical. When developing complex software applications, the possibility of errors or bugs increases. Therefore, software testing is essential as it promptly identifies issues and defects within the written code.
Testing is performed before the release of the software application. It ensures the application passes through quality assurance (QA) and aligns with user-defined criteria and specifications, resulting in exceptional software applications.
Enhancing security is crucial when users share personal information using software applications. To prevent unauthorized access by hackers, it is imperative to perform security testing before releasing the software application. This will ensure secure applications, providing users with safety and confidence.
Testing software contributes to enhanced user trust. While expecting a completely bug-free software application may be unrealistic, a stable and reliable application that consistently meets users’ needs leads to positive long-term user experiences.
Performance testing, a type of non-functional testing, measures how well an application performs with varying workloads. This includes factors like user traffic, data volume, and transaction counts. Identifying scalability limits and potential issues, such as exceeding certain thresholds, is crucial for uninterrupted application functionality.

Seven Principles of Software Testing

When understanding types of software testing, it is important to know specific guidelines that allow the QA to plan better and design the test case. Those guidelines let QA effectively identify defects by performing robust software testing and improving the overall quality of the developed software application.

Here are those set of principles:

Testing reveals the presence of defects: The primary goal is to uncover as many bugs as possible, including code errors, missing requirements, incorrect functionality, and other issues.
Detailed testing is not possible: Detailed planning and evaluating the testing process prevent the need to test every single line of code. Given the impossibility of testing all possible combinations and scenarios in software applications, testers must prioritize the most critical and high-risk areas.
Early testing saves time and cost: Rectifying issues in the early stages of SDLC is more convenient and cost-effective compared to addressing them towards the end of the software application life cycle.
Defects tend to cluster together: In software development, defects often concentrate in clusters, indicating that a few modules or components are responsible for most defects. Testing efforts should focus on these areas that typically exhibit the most issues.
Beware of the pesticide paradox: Repeating the same tests with identical inputs can lead to the repeated identification of the same defects. Updating testing techniques is crucial to avoiding the pesticide paradox.
Testing is context-dependent: The testing performed is possible in the context of the tested software application.
Absence of errors is a fallacy: If a software application fails to meet specified requirements, it remains unusable regardless of how many errors are discovered and fixed.
Now you have learned significant concepts of software testing, let us know about its position in the Software Development Life Cycle.

Role of Software Testing in SDLC

Software testing in the Software Development Life Cycle has traditionally been distinct from other development phases, often occurring later, post-build or execution. Consequently, if defects get detected at a late stage of software application development, there needs to be more time for rectification or retesting.

To address this, development teams are now adopting continuous testing, a methodology where development and testing collaborate throughout the SDLC. This approach allows teams to initiate testing much earlier, uncovering defects sooner when they are more manageable to fix.

To optimize the benefits of software testing, it should span every stage of the software project. The following outlines how testing contributes to overall project success:

Analysis: It involves analyzing end-user requirements, expectations, and specifications for software applications. Before starting the development process, the project manager or business manager gathers all the required information.
Design: Testers’ participation in this phase enhances their understanding of each design component and helps mitigate the risk of fundamental design flaws.
Development: This phase enables testers to perform more efficient testing against user requirements, reducing the risk of defect slippage. Testers also become aware of areas considered risky by developers, allowing them to adjust priorities accordingly.
Testing: This phase enables testers to verify and validate the software applications before release. Any previously unnoticed errors can be detected, and executing tests at various levels increases the likelihood of software having fewer errors while meeting customer needs.
Deployment: When the developed software application has been tested and all bugs and errors have been fixed, it is deployed. This includes getting ready the software application ready for release and deploying it to a live environment.
Maintenance: The maintenance phase continues until the software application development is complete. It involves fixing issues related to browser compatibility and so on. Different types of software testing are performed based on different stages or phases of development or requirements of the software application. Here, let us learn about various types of software testing in SDLC.

Software Testing Approaches

The field of software testing is exceptionally robust and includes different categories based on other purposes and aims. Here, we will discuss various types of software testing based on different approaches.

Manual Testing

Manual testing is one of the types of software testing that involves the evaluation of software or application quality through manual methods without relying on automated testing tools or the execution of test scripts. Here, the manual method means that the human testers execute test cases to find any bug or issue in the software application.

Testers engage with the software application like an end user, aiming to uncover bugs, defects, and issues that may impede the overall user experience. Similarly, developers engage in manual testing when they personally run their applications and experiment with the coded features. This form of testing is particularly suitable for small-scale assessments of personal projects due to its specific nature.

Before automating the testing process, it is imperative to subject any new software application to manual testing. Although manual software testing demands increased effort, it is essential to evaluate the feasibility of automation. It proves particularly valuable when

Analyzing user interfaces, usability, and the overall user experience.
Considering software behavior in unpredictable scenarios.
Evaluating the aesthetics and the overall feel of the software application.
Following are the types of software testing on the basis of the tester’s knowledge.

White box testing: White box testing, also known as clear-box testing or structural testing, is a testing method that focuses on the internal code being tested. Testers performing white box testing possess knowledge of the code’s internal workings, including the programming language, algorithms, and data structures.
They are completely aware of the system’s internal details, including the code and its implementation. This testing method effectively uncovers code defects, such as syntax errors, boundary conditions, and control flow errors. It is also instrumental in identifying performance bottlenecks and scalability issues.

Black box testing: Black box testing involves evaluating software applications without prior knowledge of their internal workings, focusing solely on the external behavior of the code. Testers input data and observe the output generated by the system under test to understand how it responds to expected and unexpected user actions, along with evaluating response time, usability, and reliability issues.
This approach tests the software applications from a user’s perspective to determine if the system functions as expected and meets user needs. The tester only knows the inputs and expected outputs of the system, lacking knowledge of the system’s internal workings.

Grey box testing: Grey box testing, a technique that combines elements of both black box and white box testing, is used to evaluate software applications from a developer’s perspective. The focus is on testing some of the system’s internal workings without a comprehensive understanding.

Automated Testing

Automated testing is one of the types of software testing that involves the automatic execution of test cases, achieved through either reusable test scripts or with the help of automation testing frameworks or tools. In simpler terms, it refers to using software testing tools and scripts to automate test execution in software development and quality assurance processes. This process includes creating test scripts that can run automatically, eliminating the need for manual intervention. The main goal of test automation is to enhance testing efficiency and effectiveness by reducing human errors, saving time, and improving test coverage.

The flexibility of automation testing is evident through the following aspects:

Tests can be executed at any given time.
The process is faster.
It is cost-effective.
It allows quality engineers to manage a higher test volume than manual testing.
Certain test cases are considered optimal candidates for automation:
Tests are more prone to failure due to human error.
Tests that are monotonous and repetitive.
Extensive tests involving multiple data sets.
Tests are not feasible for manual execution.
Manually intensive tests that consume significant time.
Tests with high potential risk.
Tests requiring execution on various hardware and software platforms.
Another type of testing that plays a vital role in the Software Development Life Cycle and complements both manual and automated testing is continuous testing. While manual testing allows for exploratory and user-centric evaluation, and automated testing ensures quick and repetitive test execution, continuous testing seamlessly integrates into the DevOps pipeline.

Continuous testing involves integrating automated feedback at various stages of the Software Development Life Cycle to enhance speed and efficiency in deployment management. Through continuous testing, following each change made by a developer, a series of tests are carried out, and feedback on the build’s quality is provided based on the test results.

It uses manual and automated testing methods, utilizing test automation frameworks and tools. Continuous testing proves especially beneficial in situations such as:

Environments with Agile and DevOps practices, emphasizing continuous integration and deployment.
Projects requiring frequent software updates and iterative development.
Complex systems that necessitate ongoing quality assurance.

Types of Software Testing

There are many types of software testing based on how the testing process is executed in the Software Development Life Cycle. Functional and non-functional testing are two broad types of software testing, and they serve different purposes in ensuring the quality and reliability of software applications. These types of software testing are based on the aspects of the software they test.

Functional Testing

Functional testing focuses on evaluating the functional aspects of a software application. This type of testing checks the various functions of the software application, such as user interfaces, client/server applications, and functionality. Functional tests can be performed manually or automated using tools. The primary concern in functional testing is understanding what the software system does and how effectively it performs its designated functions.

Functional testing offers the following advantages:

Identifying software application functionality issues before they escalate into major issues.
Verifying that required features work as expected and evaluating the system’s ability to handle unexpected conditions.
Ensuring the software applications meet end users’ expectations and are bug-free.
Testing the software applications effectively under various conditions and scenarios.
Monitoring progress and adjusting testing plans as needed.

Types of Functional Testing

There are many different types of functional testing, which include the following:

Unit testing: It evaluates the smallest functional unit of code, a crucial step in software development that ensures code quality. This test involves writing software in small, functional units and creating a corresponding unit test for each code unit. Initially, these unit tests are written as code and then automatically executed whenever changes are made in the software code. This approach quickly identifies bugs or errors within the code if a test fails.

The core objective of unit testing is to verify that a code performs as intended, facilitating the early identification of potential issues that could impact the software application’s performance. Unit testing is integral to Test-Driven Development (TDD), a methodology emphasizing iterative testing for building high-quality software applications. Each unit must work independently of external factors or other code in unit testing, ensuring a clear interpretation of the results by testers.

The following are the types of unit testing:

Branch testing: Branch coverage testing is a method to execute each possible branch from every decision point at least once, ensuring the execution of all reachable code. It allows verification of every branch in a way that is taken as true and false. This approach helps validate all the branches in the code, ensuring that no branch leads to abnormal behavior in the application.

Gorilla testing: Gorilla testing is one of the types of software testing where testers extensively test a specific module or component of the software application. The goal is to identify and address any issues or bugs that may arise. In core, gorilla testing tests a single module or component to ensure optimal performance under high loads and extreme conditions.

Statement testing: It is a test strategy in which each statement of a code is executed at least once, equivalent to finding a path through the control-flow graph that contains all the nodes of the graph.
Expression testing: Expression testing checks errors in syntax expressions and ensures that the software application only accepts correct strings of characters in any expression. It focuses on identifying errors such as unbalanced parentheses.

Pattern testing: It is a unit testing type that aims to identify error-inducing patterns in software applications. It involves analyzing past incorrect codes or defects to discern patterns, providing developers with insights into specific details contributing to errors and the effectiveness of solutions. This data informs future cases, helping to identify, correct, and prevent the recurrence of similar defects in the same software or software programs.

Matrix testing: It evaluates all variables in a software application. The developer identifies technical and business risks, creating a list of variables for review. Each variable is assessed to determine the associated risk. Matrix testing aids in identifying underutilized or unoptimized variables.

Integration testing: Integration testing, or I&T testing or string testing, occurs once software modules are integrated to ensure smooth functioning. Compared to unit tests, integration tests focus on aspects like evaluating database interactions and ensuring the seamless working of microservices. These tests can be relatively expensive because multiple application components need to be operational. Jasmine and Mocha are considered suitable tools for integration testing.

This testing category includes various approaches, such as the top-down, bottom-up, and sandwich approaches.

Component testing: Component testing, also known as module testing, is an approach that evaluates individual modules or components within broader software applications. This form of testing concentrates on individual test objects, like modules, classes, objects, and programs, without merging them with other components.

For instance, in a website development project, after developing the website’s pages, the development team executes a unit test before releasing the build for the testing team to evaluate the components. This ensures that each software application component works correctly and meets the specified requirements.

System integration testing: System integration testing (SIT) is a form of software testing executed in an integrated hardware and software environment to validate the entire system’s behavior. It involves testing the complete, integrated system to ascertain its conformity with the specified requirements.

SIT is carried out to confirm the interactions between the modules of software applications. It focuses on verifying the high and low-level software requirements outlined in the Software Requirements Specification/Data and the Software Design Document.

Incremental integration testing: This type of software testing form evaluates a module before merging it with another one. Subsequently, the integration is tested before introducing additional modules or components.

Bottom-up integration testing: Bottom-up integration testing involves testing individual components or modules independently, starting from the lowest level of the hierarchy and gradually integrating higher-level components. This approach allows for early detection of any issues at the lower levels. It ensures that the foundational elements of the system are robust before moving on to higher levels of integration.

Top-down integration testing: Top-down integration testing takes a different approach by first testing higher-level components and gradually incorporating lower-level components. This method prioritizes testing the system’s overall functionality before diving into the specifics of individual modules. Doing so helps detect issues related to system interactions and interfaces during testing.

Sandwich integration testing: Sandwich integration testing, also called hybrid integration testing, is a technique that blends elements from both the bottom-up and top-down approaches. The goal is a harmonious combination of testing individual components and validating their interactions within the larger system. Adopting this approach enables a thorough testing strategy that encompasses the specific functionalities of each component and their integration points.

Non-incremental integration testing: In integration testing, the non-incremental method is commonly known as the big bang approach. This approach involves merging all components beforehand, and the entire software application is then subjected to testing.

**End-to-end integration testing: **This is one of the types of software testing that evaluates the interactions between the entire software application and any external systems it relies on. End-to-end integration testing aims to confirm that the entire software application and its integrated components work correctly and fulfill the specified requirements. This testing approach assists in identifying any issues or discrepancies that may arise when different modules or systems interact.

System testing: System testing is the process where a complete and integrated software system is tested to verify that it meets specified requirements. It is executed within the framework of a System Requirement Specification (SRS) and a Functional Requirement Specification (FRS).

This testing phase follows integration testing and is then followed by acceptance testing, focusing on identifying issues within the integrated units of a system. Consequently, it checks whether the overall system design and behavior are in accordance with the end user’s needs. Hence, system testing helps understand how end users will use the software applications and the potential issues they might face.

Here are different types of system testing.

End-to-end testing: End-to-end testing is a software testing methodology that validates the functionality and performance of an entire software application throughout its entire life cycle. This involves simulating authentic user scenarios and replicating live data to ensure a comprehensive evaluation. The primary goal is to detect any bugs that may arise during the integration of all components, providing that the software application functions to deliver the anticipated output.

The approach emulates the actual interactions that real users would have with the software application, aiming to ensure a seamless operational experience. It is mainly executed after integration testing and before the developed software application is ready for release.

Smoke testing: Smoke testing is a type of software testing that mainly checks whether a recent build from the development team is free from bugs. It confirms that the QA team will proceed with their testing phases.

This involves running a basic set of tests on each build to evaluate the performance and functionalities of the software applications. You can execute smoke testing whenever new software functionalities are developed and integrated into the existing build deployed in the QA/staging environment.

Sanity testing: Sanity testing is a type of software testing carried out on stable software applications built with minor code adjustments. It is alternatively referred to as surface-level testing. A sanity test aims to verify that the software application functions as anticipated following bug fixes or alterations in the code.

Monkey testing: Monkey testing involves testing an application by providing random inputs to observe its behavior and check for potential breaks. This method is particularly valuable for load testing, where numerous random inputs are used to challenge the application’s stability.

What makes up the monkey testing technique? It includes distinctive features like

There are no predefined specifications outlining what and how testing should occur.
The primary focus is on identifying issues related to dependability and performance.
Monkey testing is preferred when specific bugs remain undetected during regular testing intervals.
Automation is feasible, and integration with popular testing tools like Selenium is possible.

Happy path testing: Happy path testing, also known as golden path or sunny day testing, is a software testing technique that focuses on verifying the functionality of a system under ideal conditions. It involves using known valid inputs and ensuring the system produces the expected outputs without encountering errors or exceptions.

Acceptance testing: As your product nears completion, it’s time to consider real user feedback. This is where acceptance testing plays a role, aiming to evaluate whether the software application is ready for real-world use.

The focus is confirming whether the software applications align with user expectations and efficiently execute the intended tasks. End users perform this testing to validate and approve the software application before the developer transitions it to the production environment. Acceptance testing ensures the software meets the defined acceptance criteria and is prepared for deployment. It is typically executed in the final testing phase after unit, integration, and system testing.

Alpha testing: Alpha testing is crucial in the software testing phase. The primary objective is to detect and rectify errors or bugs before the official release of the software applications.

An internal QA team performs this testing within a controlled lab setting to ensure the quality of the software application before it reaches the production stage. Alpha testing uses both white and black box testing, evaluating the software applications’ internal structure or design and confirming the functionality of input and output. It aims to identify and address issues before the software applications are released, ensuring a seamless experience for end-users.

Beta testing: Beta testing involves checking a software product or service in a real-world setting before its official release. This step is crucial in the Software Development Life Cycle as it helps uncover bugs and errors that may have been overlooked during the development process.

In beta testing, a selected group of users willingly test the product and offer feedback to the developers. These beta testers explore various ways of using the software, aiming to discover any issues, bugs, or usability challenges. Subsequently, they provide feedback on their experiences, reporting encountered issues.

User acceptance testing: User acceptance testing (UAT) is a specific type of acceptance testing carried out by end-users of software applications. The primary focus of UAT is to validate the software application from the user’s perspective and ensure that it meets their needs and requirements. Typically performed towards the end of the Software Development Life Cycle, UAT ensures user satisfaction.

**Regression testing: **Regression testing is a type of software testing that verifies recent code changes haven’t affected existing features. It involves re-executing a selection of previously executed test cases to ensure the functioning of existing features. The testing is crucial to confirm that new code changes do not produce any impact on existing functionalities.

Non-Functional Testing

Non-functional testing is one of the types of software testing that checks whether the software application’s non-functional aspects, such as stability, security, and usability, are functioning as anticipated. These tests occur post-functional testing and focus on enhancing software application quality. The primary objective is to evaluate a software application’s readiness based on non-functional criteria that functional testing typically overlooks.

Non-functional testing offers the following advantages:

1. Providing a higher level of security safeguarding systems against online threats.
2. Ensuring the system’s capability to handle concurrent user usage without performance degradation.
3. Contributing to the enhancement of the system’s overall efficiency.

Types of Non-Functional Testing

Here are the different types of non-functional testing:

Performance testing: Performance testing is one of the types of software testing to check how well a software application maintains stability, speed, scalability, and responsiveness under specific workloads. In other words, it includes different tests that check the speed, robustness, reliability, and appropriate sizing of the software application.

It involves the evaluation of several indicators, including browser, page, and network response times, server query processing time, the capacity to handle an optimal number of concurrent users, CPU memory consumption, and the identification and categorization of errors that may occur during the application’s use.

The primary aim of performance testing is to detect and eliminate performance-related bottlenecks within software applications, ultimately ensuring software quality. Absent some form of performance testing, system performance might suffer from sluggish response times and inconsistent user experiences with the operating system (OS).

Here are the types of performance testing:

Load testing: Load testing explores software applications’ capacity to manage a defined workload and user traffic, functioning as a form of performance testing. It proves valuable in understanding the performance and scalability of software applications, websites, and other information systems. When a software application is subjected to high traffic, it helps the developers improve the user experience and enhance reliability.

Stress testing: It is also known as endurance testing. This testing type evaluates the accessibility and robustness of software applications beyond typical functional limits. This test ensures that the software application can manage peak loads and extreme user input while identifying bottlenecks or potential issues in production.
Not only this, it can also test the software application beyond the normal operating points and verify the way it performs under extreme conditions like peak user load, maximum data volume, etc.

The following are the types of stress testing:

Distributed stress testing: In distributed stress testing, the testing process spans all users from the server. The stress server is responsible for distributing stress tests to all stress users and monitoring their status.

Application stress testing: Application stress testing focuses on uncovering defects related to data locking and blocking, network issues, and performance bottlenecks within an application.

Transactional stress testing: Transactional stress testing involves stress testing one or more transactions between two or more applications, aiming to fine-tune and optimize the system.

Systemic stress testing: Systemic stress testing, as integrated stress testing, is performed across multiple systems running on the same server. It is used to identify defects where the data of one application blocks another application.

Exploratory stress testing: Exploratory stress testing evaluates the system with unusual parameters or conditions unlikely to occur in a real scenario.

Scalability testing: It is a type of non-functional testing that checks how well software applications or networks perform as the number of user requests is adjusted, either increased or decreased. The primary goal of scalability testing is to verify the system’s capability to manage anticipated rises in user traffic, data volume, transaction counts, and frequency. This testing evaluates the software application’s ability to adapt to growing demands.

Volume testing: Volume testing is a form of software testing where the software application undergoes testing with a significant amount of data, also known as flood testing. The objective is to understand the system’s performance by increasing the volume of data in the database.

Soak testing: Soak testing, also referred to as capacity testing or longevity testing, involves evaluating the software application to identify performance-related issues such as stability and response time by applying the intended load on the software.

The software application is then checked to determine its ability to handle a substantial load for an extended period, observing its response and studying its behavior under sustained use. Soak testing is categorized under load testing.

Throttle testing: Throttle testing involves simulating a load scenario where virtual users, either all of them or a specific group, connect with a restricted connection speed. The objective is to analyze users’ response time connected through slower networks such as 3G, distant areas, or the Internet. In these tests, speed simulators or traffic shapers, along with tools incorporating this functionality, are mainly used.

Peak testing: This type of software testing evaluates how the software application responds to intensity peaks alongside a regular load. This test demonstrates the functionality of software applications after facing an increased load. Since real-world situations often involve such scenarios, measuring and testing the software application’s behavior under these conditions is valuable.

Spike testing: In this test, software application is tested with extreme increases and decreases in traffic load. The primary goal of spike testing is to understand how the software application behaves when faced with sudden increases or decreases in user load and to figure out the recovery time after a spike in user load.

Stability testing: This checks the quality and behavior of the software in different environmental parameters, evaluating the software application’s ability to continue functioning over time without failure.
Endurance testing: This type of software testing evaluates the system’s ability to handle a sustained workload over an extended period.

Usability testing: Usability testing, also referred to as user experience (UX) testing, involves evaluating the functionality of a website or web app by observing actual users as they engage with it to accomplish tasks.

Typically, in this testing approach, a select group of target end-users actively engages with the software application to uncover potential usability defects. Here, the primary focus of usability testing is evaluating the user interface and the overall user experience of a software application. Consequently, the testing process involves real users interacting with the software application to measure its ease of use, efficiency, and overall user satisfaction.

It is recommended to perform this type of software testing during the initial design phase of the Software Development Life Cycle (SDLC), offering greater insight into user expectations.

Here are the types of usability testing:

Exploratory testing: **Exploratory testing, also called ad-hoc testing, is a form of software testing where the tester can choose any available methodology to test the software. It represents an unscripted approach to software testing.
In this type of software testing, developers utilize their learning, knowledge, skills, and abilities to evaluate their developed software applications. This testing method checks the functionality and operations of the software while identifying functional and technical faults.
User Interface (UI) testing: UI testing, or user interface testing, is a type of software testing that concentrates on verifying the appearance, functionality, and usability of various user interfaces, including graphical user interface (GUI), command line interface (CLI), and voice user interface (VUI).
Accessibility testing: Accessibility testing is described as a type of software testing carried out to ensure that the software application being tested is user-friendly for people with disabilities, such as those with hearing impairments, color blindness, elderly individuals, and other disadvantaged groups.
Compatibility testing: It is one of the crucial non-functional tests that ensure your software application can operate seamlessly across diverse hardware, operating systems, applications, network environments, or mobile devices.

There are two categories of version checking in compatibility testing:

1.** Backward compatibility testing**: It involves verifying the behavior and compatibility of the developed hardware or software with its older versions. This type of testing is more predictable since all the changes from the previous versions are known.
2. Forward compatibility testing: This is a process to validate the behavior and compatibility of the developed hardware or software with the newer versions. This type of testing is somewhat challenging to predict as the specific changes in the newer versions are not known in advance.

The following types of compatibility testing:

Cross-browser testing: Cross-browser testing verifies the functioning of websites across various browsers, operating systems, and devices. It includes testing the website’s functionality, performance, and user interface on various web browsers like Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and Opera. You can perform cross-browser testing in the cloud because it provides convenient software application testing across various browsers and versions without any worry about local infrastructure.

One of the most used cloud-based platforms is LambdaTest – it is a test orchestration and test execution cloud platform that enables you to perform manual and automation testing for web and mobile applications across on-demand real browsers, devices, and operating systems on its scalable cloud grid. It is recognized as one of the top cloud-based testing platforms, offering support for automating test scripts with various testing frameworks like Selenium, Playwright, Cypress, Appium, Espresso, XCUITest, and more.

Cross-platform testing: Cross-platform testing is a testing type that ensures that an application or software application works correctly across diverse platforms, operating systems, and devices. It includes testing the application’s functionality, performance, and user interface on different platforms such as Windows, macOS, Linux, Android, iOS, and others.
Responsive testing: Responsive testing enables the evaluation of design across various screen widths, providing a genuine test of adaptivity beyond predefined screen sizes. Testing for responsiveness allows you to modify the screen’s width after entering the website’s URL, observing how the user interface adjusts in real-time.
Visual testing: Visual testing verifies if every user perceives the software application’s interface (UI) correctly. This type of testing checks that each element on a web page has the correct shape, size, and placement. Visual testing evaluates software application’s visible output against the expected design outcomes, helping identify “visual bugs” separate from strictly functional bugs in the appearance of a page or screen.

Security testing: It is a type of software testing that checks the vulnerability of the software application against cyber threats. This is done by evaluating its susceptibility to attacks and the impact of malicious or unexpected inputs on its functionality.

It offers assurance regarding the safety and reliability of software applications and their resistance to unauthorized inputs. The primary focus of security testing lies in uncovering potential weaknesses and loopholes within software applications that could lead to loss of information or hamper the organization’s reputation.

The following are the types of security testing.

Penetration testing: Penetration testing is one of the types of software testing that involves simulating attacks on software applications to obtain access to sensitive data, aiming to ascertain the software applications’ security status. These attacks can be executed internally or externally, giving information on the target system, pinpointing vulnerabilities, and revealing potential exploits that might impact the software applications. It acts as a crucial health check for software applications, providing insights to testers about the necessity for remediation and additional security measures.
Fuzz testing: This process includes sending numerous unexpected or malformed input data to the software applications to uncover potential input validation and handling vulnerabilities. A fuzzing tool sends these inputs into the software applications and observes for exceptions like crashes or information leakage. In simpler terms, fuzzing introduces unforeseen inputs into software applications and observes for any adverse reactions that could indicate security, performance, or quality gaps or issues.
Access control testing: This includes testing the access control mechanisms of the software applications to ensure that access to sensitive data is granted only to authorized users. It enables the configuration of access rules and executes a comprehensive attack to assist in identifying sections of software applications that may be accessible by unauthorized clients.
Application security testing: Application security testing (AST) aims to enhance the resistance of software applications against security threats by pinpointing weaknesses and vulnerabilities in the source code. These approaches involve testing, analyzing, and reporting on the security status of a software application throughout the Software Development Life Cycle (SDLC). There are two primary approaches:
Static Application Security Testing (SAST): It uses a white box testing approach, where testers evaluate the inner workings of software applications. It inspects static source code and provides reports on security weaknesses.
Dynamic Application Security Testing (DAST): It adopts a black box testing approach, executing code and inspecting it in runtime to detect potential security vulnerabilities. This includes validating issues related to query strings, requests and responses, script usage, memory leakage, cookie and session handling, authentication, execution of third-party components, data injection, and DOM injection.
API security testing: This is one of the types of software testing that has a crucial role in uncovering vulnerabilities within software application programming interfaces (APIs) and web services. This helps the developers address and fix these vulnerabilities. We know that APIs grant access to sensitive data and can serve as potential entry points for attackers into internal systems. Thus, exhaustive and consistent testing of APIs acts as a protective measure against unauthorized access and misuse.

OVERVIEW

Test scripts are a set of instructions or procedures written in a scripting language that are used to execute a series of test cases on a software application or system. In other words, test scripts are line-by-line descriptions that include related information and must be performed to validate the application under test. It lists the steps that need to be taken to meet the expected results.

In the Software Development Life Cycle (SDLC), testing is the phase that ensures the fixation of any bug or error. However, software applications have diverse components and functionalities that must be tested. It is essential to include all such aspects in software testing to ensure the quality of the software applications. A well-written test script allows the QA team to test each software application component on various environments.

This comprehensive guide aims to provide a detailed understanding of testing scripts, their significance, and how to create effective test scripts for successful testing.

What are Test Scripts?

Testing scripts are detailed, step-by-step instructions used to test a test case, encompassing individual steps to check and verify each functionality. These scripts are programs that execute tests on software products or applications. Testers must write and run these scripts to confirm if the application meets the business requirements.

We all know that test cases are the foundation for creating test scripts. There can be multiple scripts and different testing environments in a single test case. While most scripts are associated with automation testing, they can also be part of manual testing. However, testers write automated scripts to generate data for testing various functionalities.

Typically, these scripts run automatically, checking each test case with different input data. Python, Ruby, Perl, Java, VB Script, etc., are some scripting languages used for writing test scripts. Once written, a test script can execute multiple test instances to assess a single application function. Due to their detailed and extensive nature, writing scripts in a reusable format is an excellent practice that simplifies the tester's work.

Why Use Test Script?

Using test scripts in the software testing process offers several advantages, which is why they are commonly employed in testing activities. They contain information regarding the function of the software applications, which needs to be performed to validate and verify the working of the software application. Here are some of the key reasons why to use test scripts.

Comprehensive Testing: Provides a dependable means of ensuring that no steps are overlooked during testing, leading to accurate and desired testing outcomes.
Specific User Requirements: Scripts are particularly valuable when user requirements are clear, helping to meet precise criteria.
Controlled User Performance: It allows for controlled and structured user interactions, ensuring consistent and reliable testing.
Unambiguous Execution: When testers navigate software freely and assume expected outcomes, test scripts prevent ambiguities and provide clear directions for each test scenario.
Reduced Errors: A well-prepared test script minimizes the likelihood of errors during the testing process, enhancing overall testing efficiency and effectiveness.

How to Write a Test Script

Creating a test script can be approached in several ways, each with its unique methodology and requirements.

Record/Playback Method:

In this approach, instead of writing code from scratch, testers record the user's actions. This method doesn't require initial coding but may need coding later to rectify errors or refine the automation process.
It's simpler than crafting an entire test script manually, as it provides a complete code base to start with. This method is often utilized with user-friendly programming languages like VBScript.
Keyword/Data-Driven Scripting:

This technique establishes a distinct division between testers and developers. In data-driven scripting, testers define tests using keywords, without needing to understand the underlying code.
The responsibility of developers is to create and maintain the test script code corresponding to these keywords. Testers, therefore, do not have to be concerned with the system's intricacies but are dependent on development resources for testing any new features automatically.
Writing Code Using a Programming Language:

For those preferring to script tests using programming languages, there's usually the option to record/playback and generate a basic script.
As a tester, you'll eventually need to move beyond simple record/playback and learn to code straightforward scripts. It's crucial to recognize that the choice of programming language for test scripting is independent of the language used in the application's development. For instance, even if the application is developed in Java, it doesn't necessitate writing test scripts in Java, which might be challenging to learn. Instead, you can opt for simpler languages like JavaScript or Ruby, or any other language you're comfortable with.

Type of Test Scripts

Typically, scripts are divided into two types aligned with manual and automated testing approaches. Here are some of those:

Manual Test Scripts

Manual test scripts are mainly written and executed by human testers without assistance from automation tools. They only adhere to a predetermined set of steps and instructions to manually assess the software applications. This approach proves valuable for exploratory testing, usability testing, ad-hoc testing, and scenarios that evade automation. Despite its resource-intensive nature, manual testing offers a unique advantage in detecting specific issues that may bypass the automated testing approach.

Automated Test Scripts

On the other hand, automated scripts are particularly written in a programming language and run with the help of automation testing tools. These scripts use automation testing frameworks to mimic user interactions, interact with the application, and automatically verify expected outcomes. Within the category of automated scripts, there are further subtypes contingent on the level of testing and the extent of automation.

testing
Unit Testing Scripts: These concentrate on assessing individual units or components of the software applications, typically composed by developers during the development phase.
Integration Testing Scripts: These ascertain the seamless interaction between multiple components, ensuring maintained operations.
Functional Testing Scripts: These validate that the software application functions impeccably per the specified requirements.
Regression Testing Scripts: These affirm that existing functionalities remain unaffected following new changes or updates done in the software applications.
Performance Testing Scripts: These help the application performance under diverse load conditions.
End-to-End (E2E) Testing Scripts These simulate real-world scenarios to comprehensively evaluate the entire application flow from inception to completion.
Smoke Testing Scripts: These are swift assessments aimed at verifying the basic functionality of the software application after significant updates.
Security Testing Scripts: These assess the software application's resilience against security threats.
The choice between manual and automated testing depends on the specific software project requirements, complexity, and the available resources. Manual and automation testing is often deployed to ensure exhaustive test coverage and detect any vulnerabilities or discrepancies within the application.

Understanding Test Script Template

Writing test scripts involves a template, which eases this process in software testing. It is a standardized document with pre-selected and essential information for creating good-quality scripts. Such documents can be reused whenever there is a need to develop scripts for any test. These scripts serve as testers' guidelines, ensuring consistency and uniformity in structure and content.

The test script template outlines the required format and specifies what information should be incorporated into each test case. Generally, a test script template has sections on the test case name, test objective, test environment, expected result, and others. Its detailed information is as follows.

The test case name: It is a unique identifier or name of the test cases to differentiate it from others.
Test objective: It highlights the objective of the test cases.
Test steps: It gives detailed steps to run during the test.
Expected result: It includes information on the specific outcomes expected when test steps are run accurately.
Test data: It has specific data or inputs needed for test cases. It includes values, parameters, or variables that the test case needs to process during its execution.
Test environment: It has information on hardware, software, operation systems, and configurations.
Test preconditions: These are the starting points or prerequisites necessary for the test to be valid and accurate.
Test execution steps: It has the instruction to run a test case with particular information on setup and configuration.
Actual result: The real outcomes observed when the test is executed.
Pass and fail criteria: These criteria show test cases that have passed or failed based on expected and actual results.
Notes and comments: Any additional notes, comments, or observations related to the test case or its execution.
Utilizing a standardized template within the team helps save time and reduce errors in software testing. It also promotes consistent script creation and fosters effective communication among team members.

Information in Test Script

What makes test scripts beneficial? A well-written test script always includes valuable information. This information serves the purpose or aim of the script, outlining the actions to be performed during software testing.

The key components of potential information are as follows.

Inputs and Expected Results: The test script contains the raw content, including inputs and sometimes the expected results.
User Information: This section outlines the user-related details, such as the data to be provided to the script, the required software state during script execution, and the software's condition after the test.
Usage Information: Testers may include additional useful information, such as explanations of specific usage scenarios or references to related tests that might require modifications.
Annotation: Comments embedded within the script explain the logical steps and actions performed with the software being tested.
Including this essential information ensures the test script is clear, comprehensive, and effective in validating the software's functionality.

When to Use the Test Script Approach?

There are various scenarios where the test script approach is employed. While the approaches mentioned earlier are prevalent in software testing, there are instances in the testing process where they are essential.

Testing scripts come in handy for automating repetitive or manual tests, saving time and effort.
In regression testing, they enable the execution of multiple test cases to check for changes in new code.
For large and complex software applications, scripts simplify the management of numerous test cases.
In data-driven testing, they execute multiple test data sets efficiently.
They are also valuable in load and performance testing, simulating multiple users, and test scenarios.
Hence, using the test script approach in these scenarios enhances the testing process's efficiency, accuracy, and reliability, leading to better software quality.

Now, let us understand in detail test scripts with examples in the next section.

Test Scripting Tools

The software applications, which possess user-friendly interfaces, are designed to facilitate the seamless creation, editing, and execution of scripts. These tools empower testers and developers alike to write scripts without requiring extensive programming knowledge. Some test scripting tools include the following:

Selenium: It is one of the most used automation testing tools, which is open source. A fantastic feature of Selenium is that it supports multiple programming languages like Java, Python, and C#. It helps testers to interact with web elements that mimic user actions and verify the expected outcome.

Cypress: Cypress is a modern JavaScript-based test automation tool focusing on front-end testing. Cypress offers a developer-friendly environment replete with real-time reloading and advanced debugging capabilities.

Test Scripting Frameworks

Test automation frameworks provide a structured approach to effectively organize and manage test automation scripts, ensuring their reusability and scalability and simplifying the long-term maintenance of test automation projects. Various test automation scripting frameworks encompass these aspects. Mentioned below are some of the major categorizations of the frameworks.

Data-driven Framework: This framework divides test data from test scripts and helps the software testers set up and execute the tests with diverse datasets. It will, in turn, enrich test coverage and mitigate redundancy.

Keyword-driven Framework: It is the framework where the test cases adopt a tabular format, and the inclusion of keywords represents various test actions. With the help of the framework, testers can quickly write scripts without going deep into programming and using predefined keywords.

Behavior-driven Development (BDDFramework: BDD frameworks, like the Cucumber framework, develop collaboration between technical and non-technical team members. These scripts are written in a human-readable format using the Gherkin language. It eventually leads to creating better communication and understanding.

Hybrid Framework: Hybrid frameworks combine the strengths of multiple frameworks used to write scripts. It gives the testers the flexibility to leverage the advantages of each approach. It provides adaptability to meet diverse testing needs.

Page Object Model (POM): POM, a design pattern, creates a logical representation of web pages, effectively separating page elements from test logic, thus enhancing test script maintainability and reusability.

Selecting the appropriate test scripting tools and frameworks mainly depends on various factors, including requirement analysis, application type, team expertise, and the scalability of the automation effort. The rightly chosen tools and frameworks streamline the automation process, expand test coverage, and ultimately contribute to the overall success of software testing endeavors.

Now, let us understand how to write a test script.

Test Script Development Process

Writing test scripts follow a set of processes to address all the required testing needs. Some primary phases of test script development allow for writing quality scripts.

test-script-development
Requirement Gathering and Analysis
Before indulging in writing testing scripts, the testing team collaborates with stakeholders like product owners, developers, and business analysts to have information on the software requirements for the tested application. The main aim of this phase is to understand the function, performance, and behavior of the software applications so that the script includes all the related test cases that require testing.

Here, the software testers carefully evaluate the requirement so that they can identify the testable scenarios, any underlying risks, or specific conditions that need to be covered by the test scripts.

Test Design and Planning
In this phase, the software testers develop a comprehensive testing strategy based on the requirements and evaluation performed in the first phase. Here, they outline the test objective, testing scope, different testing approaches, and related factors. Based on this, the test case includes diverse types of functionality, edge cases, and test scenarios.

Test Script Implementation
When software testers develop test cases, they proceed with the implementation phase, which includes composing scripts using scripting languages and software testing tools. These scripts contain various commands that simulate interactions with the software application, such as clicking buttons, inputting data, and validating test outcomes.

Test Data Preparation
There is a requirement to have essential data that includes various test scenarios and conditions like boundary values, valid and invalid inputs, and diverse user roles to execute the test scripts. These are important for the successful execution of tests.

Test Script Execution
In the test script execution phase, the scripts are run against the software application being tested. On the different test environments and configurations, the scripts are executed so that it is easy to assess the behavior and functionality of the software application. Here, the application's responses and checks are carefully made for discrepancies between expected and actual outcomes.

Test Script Closure
A test closure report is a summary paper describing all the tests done while making software. It includes what tests were finished, the results, and a chart showing which tests are complete.

Throughout the Test Script Development Process, documentation is crucial to maintain traceability, track progress, and facilitate collaboration among team members.

Test Script Example
Below is an example of a test script that will help you understand its key concepts.

While testing login functionality on the LambdaTest website, the test script will perform the following steps.

Identification of Test Script Failures

In automation testing, failure of test scripts is a common occurrence that may create hurdles in completing the test process. Knowing about those failures and their reasons will help you overcome such issues while performing software testing. Here are some of the reasons for test script failure.

Element not found: This test script fails when it cannot locate the elements on the user interface it needs to interact with.
Synchronization issues: When a software application's response time is slower than expected, there can be timing issues. For example, some scripts involve navigating from one page to another. If the application takes longer to load the new page, the test script might fail as it cannot find the expected elements on the new page.
Incorrect data: Test data is crucial for the execution of a test script, which may include inputs and datasets to simulate real-world scenarios. However, when test data is incorrect, it may cause unexpected results or errors during the execution of the test. It may eventually lead to failure.
Environment-related issues: Lead to failures in software testing when tests are executed in different environments due to varying configurations and dependencies.
Flaky tests: This may happen in the test process where the test fails without any known or actual reasons. This makes it challenging to find any root cause of the failure. The occurrence of flaky tests in software testing also leads to the failure of the test scripts.
Code defects: Errors in the test script's implementation can lead to incorrect interactions with the application.
Now, let’s learn some debugging methods that the testers can use to address the above test script failure.

Debugging Techniques for Test Scripts

Debugging techniques in case of test case failures is one of the most crucial skills for testers. Some methods that can be used to identify and fix issues may include the following:

You may implement an approach of logging and reporting in the test scripts that allows easy tracking of the test execution flow and errors. When you analyze the logs, you can pinpoint the location of the failure.
You may comment or remove parts of the scripts to find any specific features or code snippets leading to failure. With this, you can narrow down the issue and identify the root cause more effectively.
You may leverage browser developers' tools and testing frameworks to learn more about specific elements of the software applications during the execution of the test to validate their correct identification.
Debugging features of the integrated development environments can also help the software testers step through the code and evaluate the test execution flow.

Best Practices for Writing a Test Script

To improve the writing of test scripts, here are some of the standard best practices:

The test script should be clear and requires communication with the project in charge to provide details on the software applications. However, to avoid this, consistently verify that each step in the test script is clear, concise, and coherent, facilitating a smooth testing process.
To create a test script, you should contain one specific action for testers. It helps ensure that each function is tested accurately and does not lead to skipping any software testing steps.
You should always define a clear objective for the test script to know what you want to achieve from the test and the functionality that requires testing.
To the test cases, give descriptive names, as it will help you identify the main aim of the test without going through the entire script.
Clearly define each test case's test data, input values, and expected results.
You should ensure that each test case is independent and does not rely on the results of previous tests. It allows for easier debugging and isolation of issues.
An excellent practice is to create reusable code that can be applied across multiple testing scenarios.

Future Advancements in Test Scripting

Consequently, test script generation attains swiftness, enhanced efficiency, and reduced error propensity.

Moreover, AI and ML are indispensable allies in test script maintenance. When the application undergoes changes or updates, AI-based tools demonstrate their intelligence by updating the testing procedures to accommodate the modifications, thereby minimizing the effort required for regression testing. This adaptive prowess ensures that the testing procedures remain relevant and practical throughout the software development lifecycle.

Shift-Left Testing and its Impact on Test Scripts

Another critical future trend with a significant impact on test scripting and the entire testing process is Shift-Left Testing. Traditionally, software testing was a phase that transpired toward the culmination of the development cycle. However, with the emergence of Agile and DevOps methodologies, testing has been integrated earlier in the development process.

Shift-Left Testing

Shift-Left Testing advocates for the active involvement of testers right from the project's inception, enabling a close alignment with developers and other stakeholders. This paradigm shift emphasizes the early detection of defects and issues, ultimately reducing the cost and time involved in rectifying them later in the development cycle.

In software testing, Shift-Left Testing promotes the early creation of testing procedures right at the beginning of the development process, even before the actual coding begins. This proactive approach aids in defining precise testing requirements, identifying potential risks, and establishing a solid testing strategy from the outset.

By engaging testers in the early phases, Shift-Left Testing facilitates seamless collaboration between developers and testers, leading to swift feedback loops and improved software quality. Test scripts created with the Shift-Left approach serve as guiding beacons throughout the development journey, ensuring that the application adheres to the desired functionality and performance requirements from the outset.

Furthermore, testing scripts evolve into dynamic and adaptive assets as testers and developers embrace close collaboration. Feedback from the early testing phases continually improves the test scripts, rendering them more potent in detecting defects and preempting issues before propagating to later stages of development.

Now that you have learned about testing scripts, you must have analyzed how they differ from the test case. Let us get brief on this in the below section.

Conclusion

Test Scripts refer to detailed descriptions that outline the system transactions necessary for validating the application or system under test, guiding testers through the testing process. On the other hand, a Test Case is a step-by-step procedure used to test an application, while a Test Script provides instructions for automated application testing. There are three methods to create test scripts: record/playback, keyword/data-driven scripting, and writing code using a programming language.

Ensure your test script is clear and focuses on a specific action for testers to execute. Using a test script is the most reliable approach to ensure comprehensive testing, leaving no space for omissions and guaranteeing accurate results per the desired testing plan. A Test Script Template is a reusable, formatted document containing essential information for creating a practical test script.

What is Acceptance Testing

Nazneen Ahmad — Mon, 01 Jul 2024 12:41:45 +0000

Acceptance testing involves validating an acceptance of the software application from the user's perspective. The software application is evaluated for compliance with business requirements to determine whether it is acceptable for release.

Performing tests in the Software Development Life Cycle (SDLC) is crucial to verify the software application for any bugs and quality. Throughout the SDLC process, multiple tests are performed to ensure the application meets the Software Requirement Specifications (SRS) before its release. Among those tests, acceptance testing is performed at the end of the Software Development Life Cycle after system testing. With this, you can verify whether the developed software application is ready for acceptance by the end user.

Acceptance testing focuses on verifying the application’s functionality from the end-user perspective without knowing the application's internal structure or implementation details. Due to this, acceptance testing is regarded as a type of black box testing. This approach helps ensure that the application meets user requirements and expectations.

What is Acceptance Testing?

Acceptance testing is a formal process that assesses whether a system meets user needs, requirements, and business processes, enabling users and customers to determine system acceptance.

Acceptance testing, or pre-production testing, checks whether the software application satisfies the acceptance criteria. It enables the end user and customer to decide whether or not it should be accepted by conducting formal testing of user needs, requirements, and business processes

The end-users and the QA team run acceptance tests at the last phase of the Software Testing Life Cycle (STLC). However, business analysts, support teams, users of applications, and others can also be involved in acceptance testing to provide feedback. They perform acceptance tests on two different conditions. First, after completion of system testing, and second, before the application is made available for actual use.

The primary purpose of the acceptance tests is to determine whether the developed software application is appropriate for its release. To accomplish this, the testing team releases the software application to the users after performing system testing. The user checks the application's function for acceptance in the controlled environment that simulates real-world usage scenarios. The software application is released on the market after fulfilling the acceptance criteria.

Acceptance tests intend to engage end-users of the developed software applications in the testing process to seek feedback and improvise them. However, the purpose of the acceptance tests is not limited to this. Below are some crucial purposes of acceptance tests that signify their importance.

Why Acceptance Testing?

In the Software Testing Life Cycle, at first, unit testing is performed, followed by integration testing and system testing. On their completion, we finally perform acceptance testing.

You may have a common question: when a software application undergoes several tests (unit, integration, and then system testing) before its final release, why do we need an acceptance test? This is because, at a later stage of the development process of an application, the end user should check for its functionality and work to ensure it meets their expectation.

Here are a few other reasons why the end-user and testers should conduct acceptance tests:

To ensure the reliability of the software application that meets user requirements.
To verify that the software application meets the quality standards and is ready for the software release.
To test the software application to identify defects and issues before software release to end-users. Thus, it lowers the risk of any extra cost in testing the application after its release by timely fixing the errors and bugs.
Verifies that software applications work as expected, giving a positive user experience.
Ensures that the software application gets easily integrated with the other third-party tools and works appropriately in different browsers, devices, and OS.
Seek feedback and insight to identify areas of improvement in requirement gathering and testing.
Ensures that developed software application meets crucial compliance and security standards.

Example of Acceptance Testing

Now that you know the importance of acceptance testing, let us understand its practical application by stating examples. It will give you a clear idea of what and how exactly the acceptance test works.

Suppose a software application requires adding new functionality to generate random numbers. Before the application is released to the market, an acceptance test will be performed. Here, the application's end-user will test the features in a controlled testing environment.

The application will go live on passing the test, and beta testers will test those on real devices. If the feedback gives quality assurance to the application, it will then be available to all the software application users.

Benefits of Acceptance Testing

This section will look at the benefit of acceptance tests, making it a critical step in software testing. Some of those are:

You can find errors and bugs in the software applications during the functional testing phase.
You can check how well the software applications are developed and find any scope for improvement.
It is possible to seek instant feedback from the end-user on the software application. Considering the feedback, quick changes or modifications can be made.
Performing acceptance tests, there will be no risk of getting any issues or bugs post-release.
It gives assurance that the developed software application is user-friendly and thus improves end-user satisfaction.

Types of Acceptance Testing

Acceptance testing is categorized into multiple types to verify that software applications are tested for each crucial area of acceptance. To understand this, we need to know its different types well.

Below are the following types of acceptance tests:

User Acceptance Testing (UAT)

User Acceptance Testing is the test performed on software applications to determine their functionality according to the user's requirements and perspective. The defined specifications by the end users are used to perform UAT to check whether the application fulfills it. UAT is done to check the software application's usability and whether it meets the business objective and is ready for release.

End-users or a group of representative users can be asked to test the software applications to verify the desired outcome related to their functionality. For this, you must create test scenarios and test cases that the end users will use to ensure their expected functionalities.

Business Acceptance Testing (BAT)

Business Acceptance Testing is performed to verify the developed software application against the business needs. If you perform BAT, focus on the user stories and end-user views related to the functionality of the software application. This test should not be skipped because applications passing the UAT may fail BAT. Therefore, addressing the business benefits (finances) and purposes is ensured through BAT.

To perform BAT, the testing team needs to understand the domain and end-user business well. However, this may be quite challenging due to the changing market scenario and technological advancement.

Therefore, you can use change in requirements as the test scenario that needs to be executed into the software application. Hence, BAT should not be outweighed in the development process of software applications.

Contract Acceptance Testing (CAT)

Contract Acceptance Testing is performed in the software application to test it against the pre-defined and agreed-upon criteria in a contract. Here, the contract means that when the software application is ready for release, the acceptance tests should be conducted within a specific time and address all acceptance use cases.

Service Level Agreement (SLA) is the contract specifying that payment will be made after the application meets all requirements and shows whether the contract is fulfilled. Further, it will also define the testing period, testing area, and conditions for error if encountered in the future. Such a contract can be signed before the software application is released.

Regulations Acceptance Testing (RAT)

Regulations Acceptance Testing (RAT) is performed to ensure that developed software applications align with the set rules and regulations by the country's government where the application will be released. Such tests should be performed for all applications because rules and regulations defined by their governing authorities may vary according to the country.

For example, you can perform RAT to check the compliance of the software application having a payment page with the Payment Card Industry Data Security Standard (PCI DSS) requirements. Some of those could be access controls, secure credit card data storage, and data encryption in transit.

Operational Acceptance Testing (OAT)

Operational Acceptance Testing (OAT), part of non-functional testing, is performed to verify and check the operational readiness of the software application before it gets released in the market. In other words, OAT is performed to verify that the application meets the operational requirements, user expectations, and performance standards.

Some aspects of operational requirements like recovery, maintainability, reliability, and compatibility are tested in OAT. Addressing such operational requirements, you can verify and validate software applications' effectiveness in a real-world environment in which they will be used. Thus, the stability of software applications can be checked by performing OAT.

Alpha Testing

Alpha testing is performed by the alpha tester, where the software applications are tested in their development or test environment. Based on the feedback and suggestion by the alpha testers, the application is enhanced for its usage by fixing specific bugs. Alpha testing's primary purpose is to evaluate the software's overall performance, functionality, and usability in a controlled environment.

Once the software application successfully passes alpha testing by addressing any issue and bug, it may move on to beta testing, which is tested by a larger group of users or testers in a more real-world environment.

Beta Testing

Beta testing is performed by end-users outside the development team to find any remaining bugs before applications are released to the market. In other words, beta testing validates the functionality of the software application in more real-world environments considering comprehensive usage scenarios.

With beta testing, it is possible to identify any issues or bugs not found in alpha testing. This basically checks the quality of the developed software application. Based on this, feedback is given to the development team to improvise the application before its release.

Acceptance Testing Criteria

When we run acceptance tests, several sets of predefined requirements are crucial to be addressed for the application without any missing. It helps to have reliable and highly functional software applications. Let us learn those in this section.

To run acceptance tests, it is imperative to address the set of prerequisites against which the software application will be tested. Those sets of prerequisites and conditions are termed acceptance criteria. They are the set of accepted conditions or features required in the developed software application to get accepted by end-users.

The acceptance criteria function as the checklist which verifies the application and ensures its functions as intended without any bugs. Here is the acceptance criterion list, which should be prepared before the software application development.

Functional requirement:The application should be able to function and perform specific intended tasks as directed by the users.
Performance requirement:The application should meet all the performance requirements specified by the users, like response time, availability (represents the percentage of time the application is operational and accessible to users), and throughput (a measure of the amount of work an application can perform within a given time frame).
Usability requirement:The application should meet the usability requirements like user interface design and navigation.
Security requirement:The application should meet data privacy and integrity requirements.
Compatibility requirement:The application should be compatible with different browsers, platforms, and operating systems.
Regulatory requirement:The application should have regulatory requirements like compliance with rules and regulations set by the governing body of a country.
However, specific criteria should be considered before and after acceptance testing, termed entry and exit criteria. Let us learn this from the below-given section.

Entry and Exit Criteria of Acceptance Tests

Similar to other phases of software testing, acceptance tests have entry and exit criteria. The entry and exit criteria are crucial elements of the acceptance tests that help measure the testing process to be well-defined, effective, and controlled.

Entry criteria

Before performing acceptance testing, one needs to verify the following criteria:

Was system testing completed or not?
Are all major bugs or errors fixed or not?
Are user stories present and understandable?
Is the Requirement Traceability Matrix (RTM) updated or not?
Is the acceptance testbed present or not?
Is the test environment ready for an acceptance test, including hardware, software, and network configurations?

Exit criteria

Before completing the acceptance tests, it’s essential to verify the following criteria:

All acceptance tests are successfully executed and passed.
Major bugs and errors are fixed and retested.
All acceptance criteria were met.
The end-user gave a sign-off on the acceptance test results, indicating that they approved the application for production deployment.
Acceptance Test Tools
To address the criteria mentioned above, there are certain software testing tools through which they can run acceptance tests. It not only eases the work and saves time but also ensures the reliability of the software application.

Below are some acceptance test tools you can choose depending on your requirements.

Steps to perform Acceptance Testing

Acceptance testing is a crucial part of the software development process. Being the final stage of testing, it is crucial to perform it accurately to ensure that the software application meets the Software Requirement Specifications (SRS) of the users.

Therefore, following a structured approach that covers all possible scenarios and simulates real-world usage of the software application is crucial.

acceptance-testing-requirement-analysis
Here, we will explain the steps to run an acceptance test:

Requirement Analysis
In the first step, the testing team gathers the required documentation for the software application from the end-users through direct communication or other means like workshops. Some of the required documentation includes Software Requirement Specifications, Business Requirement Documents, use cases, workflow diagrams, and a designed data matrix. It will give a clear scenario for testing the software application.

In this phase, the testing team evaluates the required documents based on the software application's objective. The team analyzes and breaks the information into smaller, manageable units. At this point, you have to ensure that requirement is clear and concise.

When the requirements are defined, you have to validate them in the next step. This could be done by reviewing the requirement with the end users to ensure they are correct and appropriate. Based on this, acceptance criteria are created by addressing that it is measurable and clearly defined. Next, we move forward to create a test plan.

Create a Test Plan
Test plan is crucial as it ensures the testing process is well-structured, organized, and comprehensive. To create a test plan, you must outline the attributes of an acceptance test plan, which are as follows:

Introduction
Acceptance Test Category
Operation Environment
Test Case ID
Test Case Title
Test Case Objective
Test Procedure
Test Schedule

Resources
This will provide a roadmap for the testing process, ensuring that all aspects of the software are thoroughly tested and that the acceptance criteria are met.

Test Case Design
Based on the test plan, the next step is to write a test case. Test cases are written by the testers that cover all the requirements and acceptance criteria. It should also simulate the real-world scenario and address all software functionality.

You have to prioritize the test case based on their importance to the acceptance criteria defined in the test plan. This will ensure that the most critical functionality is tested first. Following this, test cases should be reviewed and validated to ensure they are accurate and complete. One can document the test case in a test case repository, which is a centralized location for all test cases.

Test Case Execution
After the test case is written, you have to execute those test cases in a controlled environment like a test lab. You should set up a test environment that mimics the real environment in which the software application runs and serves its intended users. You should also ensure the availability of all test data and the required software and hardware components installed.

During this phase, all the acceptance test cases must be executed individually, along with recording the result for each test case. If the test case fails, report the result to the developers to get it resolved. You should include the following attributes in the acceptance test reports:

Report ID
Results summary of every test non-conformity
Results summary of every test failure
Test logs location
Testers name and the time the tests were performed
To-do list summary
Approval decision

Review Test Result
Once all the test cases are executed and defects are resolved, you must review the test result. You should verify the error reported in previous test cycles for its fixation by the developers. Further, for the failed test cases, you should retest them after their fix. It is a crucial step in acceptance tests as it helps to ensure that the defect is resolved and the test case passed successfully.

You have to document the result of the test case execution by including all test case details. It should then be reviewed to determine if the developed software application meets the acceptance criteria. The software application is ready for release if it meets the acceptance criteria.

Get Sign-off
When software applications successfully pass the acceptance tests, it is important to seek sign-off from the end user. This will confirm that the end user is satisfied with the software application and meets the acceptance criteria.

The best approach for acceptance tests is to perform in a cloud-based platform. It offers agility to the process and simulates real-world usage scenarios. You can test the application's performance under varying conditions, ensuring it meets end users' expectations. Testing on the cloud helps eliminate challenges concerning maintaining in-house device labs, scalability, etc.

Let us learn this in detail from the below section.

How to run Acceptance Tests on the Cloud?

The steps mentioned above to run acceptance tests can be best executed in the cloud-based platform, which offers scalability, flexibility, security, and reliability. It can lower the infrastructure cost and ensure fast test execution.

Acceptance Testing Challenges and Solutions

While performing acceptance testing, certain challenges are encountered, which can create hurdles in the software release process. The testers should address such bottlenecks to eliminate any risk involved.

Lack of clear requirements

Acceptance tests are performed based on the SRS to ensure that the developed software application functions as per user expectations.

However, one of the major challenges in acceptance tests is the lack of clear requirements from the end user. Without any clear requirements, it is difficult to define acceptance criteria that must be met by the software application to be acceptable to the users.

Due to a lack of clear requirements, confusion, delays, and reworks may arise, which can delay software release and increase the cost of software development. This also may not give a positive user experience.

Solution: You must gather and document clear, specific, and measurable requirements before initiating the acceptance tests.

Time and resource constraints

Acceptance tests could be time-consuming if the application has specific high-impact issues. Further, this may also require significant software and hardware resources. However, in situations where you have to release the software application with a tight deadline, time and resource constraints can be significant challenges.

You have to work under pressure to complete testing on a tight schedule and budget. This can cause shortcuts, errors, and poor test coverage.

Solution: Therefore, planning and allocating sufficient time and resources for acceptance tests is essential to ensure it is performed thoroughly and effectively.

Communication gaps between teams

Acceptance tests are executed not only by the testers, but end-users, project managers, and others. They can have different priorities, expectations, and communication styles. Hence, a communication gap in the acceptance tests can prevail, which may create issues in completing the timely release of software applications.

Solution: Establishing effective communication channels and processes is crucial to ensure all team members are informed, engaged, and aligned. You may have regular meetings, status updates, and documentation to establish team communication and collaboration.

Acceptance Testing Best Practices

Effective acceptance testing is critical for a successful software release to meet user requirements. Even though there are some challenges with the acceptance tests, as explained below, we can incorporate its best practices to improve it.

Below are some best practices for acceptance tests, providing guidance and strategies to the team to ensure the success of their testing process.

The testers, developers, end-users, project managers, and others should be involved in the early stage of the software development life cycle. It will help to get defined requirements beforehand, and followed to this; the software could be developed accordingly with fulfilling the SRS.
Acceptance test cases should be well-defined, measurable, and specific. This will help to ensure that acceptance criteria are clear and the testing process is focused.
The test environment should mimic the real-world conditions in which the software application will be used. This can help to identify and resolve issues that may not be apparent in a simulated environment.
You should have proper documentation of the acceptance testing, which must have information on the test plan, test case, and defect reports. Such documentation is important as it ensures accountability, traceability, and transparency.
Regular communication and progress reporting, including test results, defect reports, and other metrics, should be established. This can help build trust, promote collaboration, and promptly address issues.

Mobile App Development: A Complete Guide With Best Practices

Nazneen Ahmad — Mon, 10 Jun 2024 11:23:07 +0000

OVERVIEW

Mobile app development is the process of developing applications for devices such as smartphones and tablets. This field has significantly surged in recent years, primarily due to the increasing prevalence of mobile devices and the demand for mobile apps in everyday life.

According to Statista, between 2024 and 2029, the worldwide smartphone user count is projected to grow steadily, adding 1.5 billion users, marking a 30.6 percent increase. By 2029, after fifteen years of consecutive growth, the smartphone user base is expected to reach a new high of 6.4 billion users.

worldwide smartphone user count

Corresponding to the increase in mobile devices, mobile app development is also reaching a high peak to meet the high demand for mobile applications. Organizations invest in developing highly featured applications as they offer an opportunity to connect with users, perform crucial tasks, and gain good revenue. Thus, having a good understanding of mobile app development is one of the most demanding web developer skills. It will help you build engaging mobile apps.

This tutorial is dedicated to explaining what mobile apps are, their types, mobile app development, testing, and more. We will also learn the common mobile app development platforms, approaches, and best practices.

So, let’s get started.

What are Mobile Apps?
A mobile application, commonly known as a mobile app, is a type of software designed to operate on mobile devices like smartphones or tablets. These apps often offer users services similar to those available on personal computers but in a more compact form. They are typically small, standalone software programs with specific functions. This concept of using app software became widespread through platforms like the Google Play Store or Apple App Store, where users can download apps for their devices. Additionally, some apps can be accessed through online marketplaces or web browsers.

Types of Mobile Appss
Different types of mobile apps offer unique features and functionality. Understanding these types can help developers choose the right approach for developing a mobile app.

Below are common mobile app types.

Native Apps: They are designed for a particular mobile device's operating system, such as Android or iOS. This means there are native Android and iOS apps, each designed for its respective platform. Due to their platform-specific nature, you can't use an Android app on an iOS device or vice versa, nor can you use an iOS app on a Windows phone or a Blackberry app on an Android phone.
Web Apps: They function similarly to native apps but are accessed through a web browser on your mobile device. Unlike standalone native apps that require downloading and installing, web apps are responsive websites that adjust their user interface based on the device used. When prompted to "install" a web app, it typically just bookmarks the website URL on your device.

Web application testing is an approach to ensure the correct functioning and performance of the web application by following a structured process.

With web application testing, detection of bugs or errors is done, and ensure that all such are removed before the web application goes live.

The primary purpose of web application testing is to fix any issues and vulnerabilities in the web application before it is released on the market. With this test, you can ensure the web application meets all the end-user requirements and provide a high-quality experience. However, it is important to conduct web application testing with accuracy.

Understanding Web Application
Web applications are application programs with interconnected modules which are loaded on the client side and delivered over the Internet through the browser interface. Developers build web applications for different uses, and their users vary from organization to individual. The commonly used web applications are webmail, online calculators, and eCommerce shops.

Which web technologies are used in building web applications? They are mainly HTML (HyperText Markup Language), CSS (Cascading Style Sheets), and JavaScript. HTML uses tags to find different elements and their interaction.

On loading a web page, HTML is compiled into a Document Object Model (DOM) that shows its structure. CSS is a style description framework mainly used to style and format visual elements of web applications. Further, JavaScript is a high-level scripting language upon which all dynamic behavior of web applications is scripted and executed.

In addition to the above technologies, JavaScript frameworks like Angular, React, and Vue are used as they give ready-to-use tools and libraries. This simplifies the process of making a complex user interface.

CSS Preprocessors like LESS and SASS allow writing and organizing CSS code efficiently. It gives features like variables, mixins, and nesting, allowing developers to maintain a reusable style across web applications. Also, the HTML templating simplifies generating dynamic HTML content.

In addition, web applications also have a backend or server-side layer, which comprises APIs built using databases. It abstracts the relevant information into contracts that can be accessed by the front end through HTTP methods using appropriate requests and credentials.

By combining these various technologies, web applications can deliver a seamless user experience with rich functionality and interactivity. The front-end technologies handle the visual presentation and user interaction, while the back-end technologies manage the data and business logic. The collaboration of these technologies enables the creation of powerful and dynamic web applications.

Updated metrics are better than outdated ones. When you test a software application, considering outdated metrics does not give an accurate estimation of its functioning. Therefore, good QA metrics are those which are regularly updated.

Relevancy
The QA metrics should be relevant to the organization’s goal and meet the Software Requirements Specification of the software application.

Measurability
The QA metric should be easily measurable to track the QA process and identify areas for improvement.

Extensive
The QA metrics should be comprehensive and extensive. This means they should be able to cover all aspects of the software application crucial to measure its quality.

How does QA Metrics improve the Test Process?
QA metrics in software testing allow tracking the status of the QA activities, assessing team effectiveness, and measuring software quality. The test analyst also uses QA metrics to determine the team's productivity and prepare for future improvement in the QA process in software development. Let's see how?

Quality assurance metrics estimate the time required by regression testing by tracking the number of tests introduced to the new update of the software application. This will help estimate the time required in testing and find the software application component that needs improvement. This help makes the QA process more efficient by ensuring the quality of the software application
Quality assurance metrics give information on the behavior and function of the software application. Due to this, QA analysts can identify and fix defects quickly.
Software testing methodologies and strategies can be better planned with QA metrics. As an outcome, the testing team can be better equipped for the new Software Development Life Cycle.
However, it is important to note that QA metrics are measurements and indicators signifying the quality of the software application. To accurately analyze the QA process and team performance, you should consider the software project’s specifications, estimate the release date and workflow of the organization, etc. However, this process can be optimized if testers follow the stages of the metric life cycle strictly.

Stages of Metrics Life Cycle
QA metrics life cycle is the process of analyzing, measuring, and reporting the software testing metrics over time. In other words, gathering data on the test, analyzing it, and reporting to estimate the success of the software application. It begins by selecting the right QA metrics to indicate progress in software application development and what must be fixed.

Based on this, you collect data from test logs, performance tests, and bug-tracking systems. All the collected data are reviewed and reported to check the functioning of the software application. Based on the information, you can make changes to the software application.

stages-of-metrics-life-cycle
Thus, tracking the QA metrics throughout the Software Development Life Cycle helps ensure that software applications are developed as per the requirement and end-user expectations. Let us see the phases of the QA metrics life cycle.

Analysis: This involves recognizing the appropriate QA metrics for testing and defining the adopted QA standards. The testing team must identify the most relevant metrics for measuring the software's effectiveness and quality. This is followed by defining QA standards which include guidelines on how to measure and report on the identified metrics, as well as guidelines on the overall testing process.
Communicate: Here, the testing team and other stakeholders are informed about the QA metrics. Further, the testing team is also trained on data points like its collection and measurement that must be addressed to process the testing metrics.
Evaluation: This involves collecting and verifying the data to ensure it is complete, accurate, and error-free. Using such data, an evaluation of the value of QA metrics is done. This includes evaluating the data to find whether the QA metrics align with the testing process's objectives and give meaningful insights into the software's quality and performance.
Report: In this phase, the testing team creates sound and compelling inferences for the data. Based on this report is created with an effective conclusion and distributed to the stakeholders and others for feedback.
Type of QA Metrics
Considering the availability of many QA metrics in software testing, they are divided into three groups for better understanding. Those three groups are as follows:

Process Metrics
The process metrics define the features and performance of the software application. It is used to improve the process efficiency of the Software Development Life Cycle. Examples of process metrics include test cycle time, defect density, and test case execution rate.

Product Metrics
It delineates software applications’ design, quality, size, performance, and complexity. Examples of product metrics include code complexity, code coverage, and defect severity.

Project Metrics
It measures the efficiency of the software testing, development team, or test tools they use to test the software application. In other words, project metrics measure the generic quality of the projects. You can estimate the team's productivity, testing costs, and any possible flaws. Examples of project metrics include cost variance, defect density, code coverage, and requirements coverage.

Type of Manual QA Metrics
Manual QA metrics is used to assess the quality and effectiveness of manual software testing efforts. You can use it to evaluate different aspects of the software testing process, like test case design, test execution, and defect management.

The two main types of manual QA metrics are as follows:

Base or Absolute Metrics
Calculated or Derivative Metrics
Base or Absolute Metrics
During the test case development and execution, the raw information/data (number of test cases executed, number of test cases) collected by the QA analyst helps to derive base metrics. Such information/data is tracked throughout the Software Testing Life Cycle in the form of the number of test cases that need to be executed, the number of test cases developed for software projects, the number of test cases passed/failed/blocked, etc.

The base metric is also called an absolute metric which is a quantitative measure based on the actual data obtained during the test case development and execution and tracked throughout the Software Testing Life Cycle. Base or absolute metrics give information that can be counted or measure specific aspects of the quality of software applications. In simple terms, they provide basic information about the testing process, such as the number of test cases written or the time to complete a testing cycle.

For example, defect density is an absolute metric because it measures the number of defects per code unit. Similarly, the number of test cases executed or the percentage of defects found are absolute metrics. These directly measure the progress of the software testing process and how close it is to completion.

There are different types of base QA metrics:

Total Number of Test Cases
It is the measure of the total number of test cases developed for testing various software application functionality.

Formula:

Total number of test cases = (number of functional requirements) x (number of test cases per requirement).
Number of Passed Test Cases
It is the measure of the number of test cases developed that have successfully passed during the software testing process.

Formula:

Number of test cases passed = (number of test cases executed) - (number of test cases failed) - (number of test cases blocked).
Number of Failed Test Cases
It measures the number of test cases that failed during the software testing process.

Formula:

Number of test cases failed = (number of test cases executed) - (number of test cases passed) - (number of test cases blocked).
Number of Blocked Test Cases
It measures the number of test cases that could not be executed due to some issue or blockers. For example, the test environment may not be correctly set up or have the required hardware or software resources to run the test case. There also might be test case design issues that lead to test case blocks.

Formula:

Number of test cases blocked = (Number of test cases designed) - (Number of test cases executed).
Number of Identified Bugs
It measures the number of bugs found, including critical and non-critical bugs. Such bugs need to be addressed and fixed by the development team.

Formula:

Number of defects found = (Number of defects accepted) + (Number of defects rejected) + (Number of defects deferred).
Number of Accepted Bugs
It measures the number of bugs identified during testing marked as valid issues leading to the non-functionality of the software application.

Formula:

Number of defects accepted = (Number of defects found) - (Number of defects rejected) - (Number of defects deferred).
Number of Rejected Bugs
It measures the number of bugs identified during testing but is not considered valid issues that could impact the functioning of the software application.

Formula:

Number of defects rejected = (Number of defects found) - (Number of defects accepted) - (Number of defects deferred).
Number of Deferred Bugs
It measures the number of bugs found but not addressed during the testing process and later deferred to the next phase.

Formula:

Number of defects deferred = (Number of defects found) - (Number of defects accepted) - (Number of defects rejected).
Number of Critical Bugs
It measures the number of critical bugs found during software testing and could lead to severe issues or non-functioning of the software application.

Formula:

Number of critical defects = (Number of defects found with severity level = Critical).
Number of determined Test Hours
It measures the total number of hours allocated or given for software testing according to the test plan.

Formula:

Number of planned test hours = (Total number of test cases) x (Average time per test case).
Number of Actual Test Hours
It measures the actual number of hours spent on the software testing process.

Formula:

Number of actual test hours = (Time started testing) - (Time ended testing)
Number of bugs detected after release
It measures the number of bugs detected in the software application after its release into the market.

Formula:

Number of bugs found after shipping = Total number of bugs reported after shipping - Number of bugs fixed after release
Calculated or Derivative Metrics
It is derived from the data gathered in the base metrics through mathematical calculations or other analytical methods. You can track calculated metrics by measuring test case execution rate, defect density, and test case effectiveness.

For example, a derivative metric could be the percentage of defects found per test case derived from the total number of defects found and the total number of test cases executed. This will help you provide more detailed and great insights into the testing process, such as identifying trends, correlations, or areas for improvement.

However, choosing the right combination of metrics is important to ensure that the derivative metric accurately reflects the intended aspect of the software application or process being measured. For this, learning about different types of calculated QA metrics is important.

Below are the various categories that help differentiate different types of QA metrics.

Test Planning
The metrics are derived to facilitate test planning which is an approach of defining test strategy, the objective of the test, resources used in software testing, and the release of software application. Using these metrics, you can have good insight into the efficiency of the testing process and further help you make informed decisions on the effective release of software applications.

Following are the metrics that help to facilitate test planning:

Passed Test Case Percentage
It measures the total percentage of passed test cases from the total executed test cases. This shows the overall effectiveness of the test cases that have succeeded in detecting bugs and indicates the quality of the software application.

Formula:

Total number of passed test cases / Total number of test cases x 100%
Failed Test Case Percentage
It measures the total percentage of failed test cases from the total executed test cases. This gives an idea of the components of software applications requiring improvements and further testing.

Formula:

Total number of failed test cases / Total number of test cases x 100%.
Blocked Test Case Percentage
It measures the blocked test cases percentage out of the total number of test cases executed. It indicates the issues and dependencies which require resolution or fixation before the continuation of the test.

Formula:

Total number of blocked test cases / Total number of test cases x 100%.
Fixed Defects Percentage
It measures the total percentage of fixed defects out of the total number of reported defects. This mainly shows the effectiveness of the development team in addressing the reported issue.

Formula:

Total number of defects fixed / Total number of defects reported x 100%.
Accepted Defects Percentage
It measures the total percentage of accepted defects out of the total number of defects reported and which are marked as valid and require fixation. This shows the accuracy and consistency of the defect-reporting process.

Formula:

Total number of defects accepted as valid / Total number of defects reported x 100%.
Defects Rejected Percentage
It measures the total percentage of rejected defects out of the total number of defects reported, which are marked as invalid and do not require any further fixation. You can get an idea of the quality of the defect reports and help build collaboration between the testing and development teams.

Formula:

Total number of defects rejected as invalid / Total number of defects reported x 100%
Defects Deferred Percentage
It measures the percentage of the defects marked as deferred for future release. When the defect is deferred, the development team has to postpone the fixes to a future release due to time constraints. This means that the testing team should decide which defects should be fixed first and assign the appropriate resources to address them effectively.

Formula:

Total number of defects deferred for future / Total number of defects reported x 100%
Critical Defects Percentage
It measures the percentage of defects marked as critical out of the total number of defects. Such metrics indicate the severity of the reported issue on the software application's functionality, usability, and safety.

Formula:

Total number of critical defects / Total number of defects reported x 100%
Average Time to Repair Defects
It measures the average time taken to fix the reported defects during software testing ranging from its first reporting to its resolution. With the less average time to repair defects, the development team's performance in resolving the reported issue is high.

Formula:

Total time taken for fixing the bugs / Total number of bugs found
Test Efforts
The test effort metrics allow us to measure the time, resources, and effort required to complete the testing. You can easily answer the question of “how long or how many or how much? With this, you will establish a baseline for test planning and help you plan and allocate your software testing resources effectively.

However, it is important to note that such metrics measurements are just average estimations, where half of the values fall over the average and half of them under.

Tests Run Per Period
It gives the measurement of the number of tests run on a particular period of time, like days or weeks

Formula:

Tests run per period = Total number of tests run / Total time taken
Test Design Efficiency
It gives an estimation of the efficiency of the test design process by measuring a number of test cases designed per unit of time.

Formula:

Test design efficiency = Total number of tests designed / Total time taken
Test Review Efficiency
It gives an estimation of the efficiency of the test review process. It measures the number of test cases reviewed per unit of time.

Formula:

Test review efficiency = Total number of tests reviewed / Total time taken
Defects Per Test Hour
It gives an estimation of the average number of defects found during a particular period of testing time.

Formula:

Defects per test hour = Total number of defects / Total number of test hours
Bugs Per Test
It gives an estimation of the average number of bugs found per test case in the software testing.

Formula:

Bugs per test = Total number of bugs found / Total number of tests
Time To Test A Bug
It gives an estimation of the average time required to retest a defect after its fixation.

Formula:

Time to test a bug = Total time taken between defect fix to retest for all defects / Total number of bugs found
Test Effectiveness
It measures software testing in terms of its ability to fix and find bugs. Test effectiveness metrics are the percentage of the total detected defects and the overall reported defect.

For example, suppose a testing team found 80 defects in a software application; the total number of defects was 100, and the test effectiveness would be 80%. This will show that the testing teams found 80% of the defects in the software application.

With such estimation and measurement, you can easily answer questions like how good the tests were or whether there is a high value of test cases. Further, test effectiveness metrics help to evaluate the quality of the individual test cases and test suites.

You can measure test effectiveness metrics by the following two means:

Metrics Based: Test Effectiveness using Defect Containment Efficiency
Test effectiveness is the ratio of the total number of defects detected before the release of the software application to the total number of defects found before and after the software application release.

You can calculate the test effectiveness percentage using the formula given below.

Formula:

(Bugs detected in 1 test / Total number of bugs found in tests + bug found after release)
When you get a high test effectiveness percentage, the test set will be better, and test case maintenance efforts will be lowered in the long term. For example, if the test effectiveness is 60%, 40% of the defects are eliminated from the software testing. You should know that test effectiveness cannot be 100%, so you should always aim to get high value and be worried if it is not 100%.

Context-Based: Test Effectiveness using Team Assessment.
Following are the cases when defect containment efficiency metrics may not be helpful:

When a software application is completely developed.
When a software application is unstable with many bugs.
When software application development has less time and resources in executing tests.
In the above cases, the QA team should focus on testing the critical features of the software application reported to have the most issues or have been modified. A context-based approach is recommended to measure the test effectiveness in such cases. This involves tailoring the software testing approach based on the specific needs and risks of a particular software application development project.

Test Coverage
Test coverage measures the extent to which a software application is tested by identifying the code or functionality included by a set of test cases. Some examples of these metrics are test case by requirement, defects per requirement, and a number of requirements.

Using the test coverage metric, you can estimate whether testing activities are completed and thus use it as the criterion to conclude software testing. Such measures signify the quality of the software applications under the testing process.

Below are the key test coverage metrics:

Test Coverage Percentage= (Number of tests runs/Number of tests to be run) X 100
Requirements Coverage= (Number of requirements coverage/Total number of requirements) X 100
Test Coverage = Number of detected faults/number of predicted defects.
Some other crucial test coverage benchmarks are explained below

Test Design Coverage
It is similar to test coverage; however, it measures the test case coverage percentage against the number of requirements. With these metrics, you can analyze the functional test design coverage, improving the test coverage. You can calculate this during the test design stage, which is measured using the formula below.

Formula:

Test Design Coverage = (Total number of requirements mapped to test cases / Total number of requirements) x 100
Test Execution Coverage
It measures the total number of test cases executed and the number of test cases pending to be executed. You can measure test execution coverage during test execution with the use of the below formula:

Formula:

Test Execution Coverage = (Total number of executed test cases or scripts / Total number of test cases or scripts planned to be executed) x 100
Test Economics
In software application testing, the cost involved depends on several factors like the number of people involved in the process, the requirement of different automation testing tools and resources for testing, and the infrastructure (servers, storage system, hardware devices) required to support the software testing activities.

Considering the factors involved, organizations must compare the planned cost of testing software applications with the actual cost. This is to ensure that the cost of the software testing process remains within budget. Here comes test economics metrics, which measure the return on investment (ROI) on testing. The key test economic metrics which help in the above are as follows:

Total Allocated Costs for Testing
It refers to the total projected costs for all the testing activities for a single software application project for an entire year. It involves both indirect and direct costs associated with software testing, like human resource costs (salary of testers), equipment costs (real devices and hardware), software costs (automation tools), and many others.

Formula:

Total allocated costs for testing = Direct costs + Indirect costs
Actual Cost of Testing
It refers to the actual amount spent on testing rather than the projected cost. You can calculate this based on cost per requirement, test case, or hour of testing.

Formula:

Actual cost of testing = Total direct costs + Total indirect costs
Budget Variance
It is the difference between the budgeted cost and the actual cost of the software application testing. It helps to measure whether the testing activities were completed within budget.

Formula:

Budget variance = Total allocated costs for testing - Actual cost of testing
Schedule Variance
It is the difference between the planned and actual testing schedules. The value will indicate whether or not the testing activities were completed on time.

Formula:

Schedule variance = Planned testing schedule - Actual testing schedule
Cost per Bug Fix
It is the cost involved in identifying and fixing a single bug during the software application testing. Such value helps you to get an idea of the efficiency and effectiveness of the testing process.

Formula:

Cost per bug fix = Total testing costs / Number of bugs found and fixed
Cost of not Testing
It is the cost involved in identifying the defects after the software application is released to the end-users. Here the cost of not testing consists of the cost of fixing the defects, customer support, and loss or damage to the organization’s reputation.

However, its calculation does not depend on any specific formula but varies with particular situations, resulting in the cost of not testing.

Test Team Metrics
This metric indicates that the allocation of work to each member of the software testing team is uniform. Test team metrics also help to check whether any team member requires a software testing process or software application project knowledge to proceed with the underlying activities. However, it is important to note that test team metrics should be used as learning measures rather than blame.

Following are the test team metrics.

The Number of Defects returned per Team Members
It is the measure that signifies the number of defects found by each team member during software testing activities. Such a metric will inform which team member has successfully identified more defects than others and those who require more training.

The Number of Open Bugs to be Retested by Each Team Member
It is the measure that indicates the number of defects found during software testing which are still open and require retesting to fix it. Such a metric will give information that identifies the team members skilled at retesting and those who require training in finding and fixing bugs.

The Number of Test Cases Allocated to Each Team Member
It is the measure that shows the number of test cases assigned to the distinct team members to execute the test. With this metric, you can easily identify which team member is allocated with how many test cases, and the basis of that workload can be adjusted.

The Number of Test Cases Executed by Each Team Member
It is the measure that shows the number of test cases executed by distinct team members involved in software testing. This will help understand which team member is efficient in executing test cases and the team members require additional support.

Test Execution Status
This metric gives insight into how many tests are executed. It also indicates how many are still pending to be executed. Using test execution status, you can evaluate the extent to which the test is covered during the software testing.

Test Execution/Defect Find Rate Tracking
This metric measures the percentage of failed tests during software application testing to the total number of tests executed. The value can be a sign for changing or modifying the software testing approach to get more passed tests by comparing the cumulative number of defects and test execution rates.

Formula:

Test Execution/Defect Find Rate = (Number of Failed Tests / Total Number of Tests) x 100%
Defect Distribution
QA metrics must also be used to track the defects found during the software testing. However, it is impossible to debug each defect in a single sprint, and bugs need to be categorized by priority, severity, and other parameters. To do this, defect distribution metrics are helpful for the teams to prioritize which defects to address first and how to allocate resources efficiently.

The following are the type of defect distribution metrics:

Defect Distribution by Cause
The defects found during the software testing are classified based on the cause of the issues, like coding errors, design flaws, or system configuration issues.

Defect Distribution by Feature/Functional Area
The defects found during the software testing are classified based on the specific feature or any functional component of the software application where they occur. This helps the team find the component of software applications more prone to error. Thus, you can prioritize testing and development accordingly.

Defect Distribution by Severity
The defects found during software testing are classified based on the severity or criticality of the issues (high, medium, and low) found in software applications. This allows the team to focus on critical errors promptly.

Defect Distribution by Priority
The defects found during software testing are classified based on the priority level (high, medium, and low). Such prioritization is based on factors like the impact of defects on end users, the probability of defects occurring, etc.

Defect Distribution by Type
The defects found are classified based on the type of issue, like functionality issues, usability issues, or performance issues. This allows the team to track the defect in the software applications by the types through which identification of an area of software application that more testing can be made.

Defect Distribution by Tester
The defects found are classified based on the tester or testing type that identified the issue, like development testers, QA testers, UAT testers, or end-users.

Defect Distribution by Test Type
The defects identified are classified based on the specific testing activity that identified the issue, like code review, walkthrough, test execution, exploratory testing, and others. With this, the team can get great insight into the effectiveness of testing activities, and based on this, they are easily adjusting their software testing strategy.

Effectiveness of Change Metrics
In software application development, changes in features or functioning are common and need to be incorporated into the software application. However, it is important to monitor the impact of such changes on the stability of the software application. The reason is that new changes or updates can induce new defects and lower the stability of the software application. Here comes the effectiveness of change metrics which measure how successful software changes are in terms of their impact on the stability and quality of the software application.

Two effectiveness change metrics are as follows:

Effect of Testing Changes
This measures the total number of defects found during the software application testing corresponding to the new changes done. For example, if the development team obtained 50 defect reports, and after classifying them, 30 were related to changes made to the software application, then the total number of defects attributable to changes would be 30.

Defect Injection Rate
It measures the average rate that new changes made in the software application are causing defects or errors. For example, if there were 20 changes made in the software application, and 60 defects were due to such changes, then the defect injection rate would be three defects per change.

Formula:

Defect Injection Rate = (Total number of problems attributable to the changes) / (Number of tested changes)
Defect Distribution Over Time Charts
It determines the increase and decrease in the total number of defects over time. Basically, it is a graphical representation that shows a number of defects reported and resolved over a period of time, for example, at the end of the Software Testing Life Cycle. You can seek information from the graph on the number of defects reported each day or week, along with the number of defects resolved or closed during the same period of time.

The defect distribution over time graph is also classified as per different categories as mentioned below:

Defect Distribution Over Time By Cause
This shows a number of defects reported over time classified by the main cause of the defects, like causes related to design, development, testing, or documentation errors.

Defect Distribution Over Time By Module
This shows the number of defects classified by the software application's module or component that had reported defects over time.

Defect Distribution Over Time By Severity
This indicates a number of defects that are classified by the severity of the defects as critical, medium, and low. Knowing this, you can prioritize defects and ensure critical issues are addressed promptly.

Defect Distribution Over Time By Platform
This shows the number of defects classified by the platform or environment where the defects were found. Here, the environment and platforms may include operating systems like Windows, macOS, Linux, Android, or iOS, as well as web browsers, databases, and other software components that the application depends on. For example, defects may be found on operating systems or web browsers.

Other Defect Metrics
Here are some other defect metrics:

Defect Removal Efficiency /Defect Gap Analysis
It is the measures that indicate the ability and extent to which the development team can manage and fix valid defects reported by the testing team. You can calculate the defect gap by taking the total number of defects submitted to the development team and a total number of defects fixed by the end of the Software Development Life Cycle.

Formula:

Defect Gap % = (Total number of defects fixed/Total number of valid defects reported) X 100
Defect Density
It is the measure that indicates the presence of the total number of defects in a software application per unit of sizes like components, lines of code function points, etc. For example, if a software application has 10,0000 lines of code, and 1000 defects were identified during testing, then the defect density would be Defect Density = 1000 / 10,0000 = 0.01 or 1%

Formula:

Defect Density = Total number of defects / Size of the software or application area
Defect Age
It measures the average time required to fix any defect by the development team. Mainly, you can measure defect age in unit days; however, for the testing team working as per rapid deployment models where they have to release weekly or daily projects, it should be measured in hours. Knowing the defect age, you can track the time from bug fixing until its complete resolution.

Formula:

Defect Age= Difference in Time created and Time-resolved
How to Calculate QA metrics?
Considering the presence of a high number of QA metrics in software testing “what is the common approach to calculating them? In this section, we will discuss common steps for calculating quality assurance metrics.

Identify the process to measure
At the first stage, you have to prepare a test plan by reviewing the Software Requirement Specification (SRS) of the software application. Then you are required to develop manual test case scenarios for testing different aspects of the application like components, user behavior, and performance. Following this, also prepare a list of testing procedures you want to optimize.

For example, the project head assigns the QA team to identify and fix application bugs and track the software testing budget.

Define baseline
On defining the QA metrics, you need to share the details with other team members, including management, for its approval. For each of the defined QA metrics, you should set baseline numbers that help to evaluate the efficiency of the testing process in each iteration.

For example, the QA team set goals to document various aspects of software testing. This may involve several test cases executed, bugs found, the cost of fixing those bugs, and the overall cost of the software testing. Here, the project head wants to limit the testing budget to 4 lakhs; this will become the baseline for the testing metrics.

Calculate the actual value
After setting the baseline, you need to perform extensive tests to find defects in the software application and make the required changes. You should document the details that you wish to track and evaluate. It is important to note that using large data sets for the analysis makes the QA metrics effective.

For example, the QA team has documented all the steps required to run software tests and estimated a total cost of 6 lakhs. This will be the actual cost of software testing. The budget variance is 2 lakhs, obtained by the difference between the actual and budget costs.

Identify areas of improvement
Now, you have to compare the actual value of the baseline number to find the area of software application to optimize. For this, continue to execute the same steps in each iteration and document the result. Based on it, prepare a detailed report on the metrics like formulas, experiments, and results.

Knowing about various QA metrics, choosing the right one for your software development projects, and using it accurately are key to planning and executing the QA process. However, QA metrics in the Agile development process are essential, and the QA team should be closely monitored to track the software testing approach and know the exact number they have to hit. When you fail to meet those QA metrics, it is important to reorient the software testing strategy.

However, when you plan the QA process, ensure to include testing on real-world environments in your testing strategy. This is because, with real device testing, it is possible to identify all possible bugs or defects in the software application being tested.

Digital experience testing platforms like LambdaTest offer a scalable cloud of 3000+ real browsers. devices, and OS combinations to automate web testing and mobile app testing. You can test on LambdaTest real device cloud to find every possible bug in software applications and get accurate results.

Further, without having accurate information on the bugs, QA metrics cannot be used to set the baseline and measure the success of the software application testing.

Key Considerations when using QA Metrics
When you use QA metrics, use them accurately. For this, you should consider certain points while using QA metrics:

You should use QA metrics as indicators, not absolutes.
You should not depend on single QA metrics to analyze the quality of the software applications.
Every team member involved in developing and testing the software application should understand what QA metric means and how they are calculated.
It is possible that QA metrics get misinterpreted. For example, a high defect count might indicate poor quality of software applications. Still, it could also mean that the testing team is doing thorough work of finding and reporting issues.
Conclusion
QA metrics are the objective and subjective measurements that QA analysts collect throughout the software development and testing process. You can understand this as the absolute count or measure of the quality of the software applications.

In this tutorial, we discussed QA metrics and their different types to track and monitor the effectiveness of software application tests. Knowing about different types and use of QA metrics, you will be able to ensure the accuracy of the various tests executed and the software application’s functionality and performance.

Grey Box Testing Tutorial: A Comprehensive Guide With Examples And Best Practices

Nazneen Ahmad — Sun, 07 May 2023 06:39:16 +0000

Grey box testing is the technique to debug and evaluate the vulnerabilities of software applications. In such a method, the testers have only limited knowledge of the internal structure or components of the software applications under test.
In the Software Development Life Cycle (SDLC), testing is the crucial phase that verifies the quality of the software application. In this development cycle, different software testing techniques like a black box and white box testing are used to evaluate the performance and function of software applications and ensure their quality.
Black box testing involves validating the software without knowledge of its internal workings. In contrast, white box testing involves validating software with a full understanding of its internal workings.
However, in some cases, having full knowledge of the internal workings of the software is impractical or impossible. This is where grey box testing comes in, combining white and black box testing elements to help debug and verify the functionality and behavior of software applications, such as code execution, database access, and server configuration.
It allows testers to identify defects that may not be visible in black box testing while providing an external perspective on the software application under test.

What is Grey Box Testing?

Grey box testing involves verifying the functionality of the software application and identifying vulnerabilities. Here, the tester is partially aware of the application's internal workings and components. However, they perform the grey box test based on their access to design documents, internal coding, database, and information about the requirements. Grey box testing evaluates web applications, performs integration and penetrating testing, tests business domains, conducts security assessments, etc.
QA creates test cases and efficiently executes them using partial information on the data structures and algorithm. This allows finding context-specific errors in web applications using the test cases, as it has all the steps presented before the test initiation. Such errors only occur under specific conditions or in a particular context. For example, an error might occur when an end-user tries to submit a form with a specific input type, but the error does not occur with other input types.
Grey box testing can be implemented in many ways, including penetration and integration testing. Such tests are non-obtrusive for the testers, meaning they do not disrupt the software application's normal functioning while testing occurs. Its primary focus is testing the interactions between different software application modules and finding any vulnerabilities attackers could exploit.
For example, if a tester finds any defects in the software application and makes code modifications to fix it, they perform retesting in real time. In this process, all levels of software applications, like the user interface or display layer, the business logic layer, the data storage layer, and the core code structure of the software, are tested. Like real-time testing, grey box testing focuses on testing all levels of any complicated software application to enhance test coverage.

Why Grey Box Testing?
Grey box testing is an integral part of the Software Testing Life Cycle (STLC) and is performed during the testing phase. In this phase, when the team executes test cases, the grey box test technique is needed to understand the internal workings and verify the functionality and performance of the software application. It is also performed to find errors that are not easily identified by performing black box testing.
While testing the software application, grey box testing helps to identify the component or part of the software application with major performance issues. However, testing done in real-world scenarios gives accurate information on the test. You can simulate real-world scenarios like data interaction or network connectivity with a grey box test.
Grey box tests also identify security vulnerabilities within the software application, like SQL injection attacks. This can be done by analyzing the code (the software application's source code) and logs (records generated by the software application that provide information about its behavior and operations).
Thus, grey box testing is required in the testing phase to ensure the software application's quality and lower the risk of bugs post-software application release.

Objectives of Grey Box Testing

The main purpose of grey box testing is to find and verify defects due to incorrect code structure and its use in the application. Some of its other associated objectives are mentioned below:
To improve the quality of the software application that covers functional testing and non-functional testing.
To save time and effort required to test the software application.
To test the software applications from the end-user's perspective

Grey Box Testing Example

To understand grey box testing, you must know its practical use that will help you analyze where and when to implement it in the Software Development Life Cycle.
Here are some examples of grey box tests.
Example 1: Suppose you are testing a website. There is an error when you click on a link. Here, grey box testers make changes in the HTML code to fix the error. In such a scenario, you are performing both white and black box testing. For example, the white box test is done while changing the code. This is because testers have access to the internal workings of the website and are making changes to the code based on that knowledge.
However, the black box test is done when the QA validates the change at the front end to test the behavior of the website without knowledge of its internal workings. Thus, its combination overall results in grey box testing. The tester has only partial knowledge of the internal workings of the website under test.
Example 2: Grey box testers analyze the error codes found in the software applications. As they have access to the error code tables, they provide the cause for the error code. For example, while testing a website, if it gets an error code "internal server error 500", and the cause of this error showing in the table is a "server error," the tester uses this information to analyze the issue further. It gives the developer details to fix rather than just raising the issue.
Example 3: Grey box testers also evaluate the log files that contain a record of events within a software application, such as errors, exceptions, and warnings. This helps them to find the root cause of the errors and gain insight into the behavior of the software application.

Advantages of Grey Box Testing

Grey box testing helps verify the quality of the software application in many different ways. You should consider its significance in testing to get started. Here are some advantages of grey box tests that give insights into how it benefits software application development.
It is possible to review the software application's code, where you can easily detect hidden bugs. In addition, it also provides a way to evaluate software applications' functionality from the end user's perspective. Thus, with grey box tests, you can detect bugs early in the software application development process.
With early detection of bugs, developers can fix them quickly. This will help avoid situations where software applications might get complicated and the fixation of bugs becomes costly.
Optimization of software applications' performance becomes easy. You can identify performance-related issues and inefficiencies in the software application. This can be done by analyzing the application's log and internal data.
Grey box tests validate software applications with both a user interface and a backend. You can test the software application from the user's perspective with some knowledge of its internal workings. This will help you to test the software application more comprehensively and find defects that may not be detected from the user interface alone
Compared with black box testing, grey box testing is a more cost-effective method. This is because it does not require specialized skills and knowledge of the testers. As grey box testers do not need to know the application's source code deeply, an organization can hire testers with a broader range of skills and lower experience levels.

Disadvantages of Grey Box Testing

Gray box testing can be very useful in testing the functionality of software applications, but it can also have some drawbacks. The following are some drawbacks associated with it.
In distributed software applications with components at different locations, grey box testing cannot trace a defect back to its source. It is because testers do not have complete knowledge of the internal working of the components of software applications. For example, any defect in one component could cause defects in other components. As the tester cannot access the first component's internal work, finding the main cause of the issues may be difficult.
Grey box testers have limited access to the internal structure of the software applications. It makes it difficult for them to transverse all possible code paths. Thus, certain defects may go undetected.
It is unsuitable for algorithm testing; instead, it focuses on functional testing.
Creating grey box test cases are complex because testers have limited knowledge of the internal interaction of components of the software application.

White Box vs. Black Box vs. Grey Box Testing

Grey box testing differs from white and black box testing. In white box testing and black box testing, testers have end-to-end knowledge of the internal structure of applications. However, in black box testing, testers are unknown of the internal structure and components of the application.
Compared with grey box testing, testers are typically known only for the internal components of applications but unaware of their interaction and associated function. Thus, grey box tests are a hybrid of black and white box testing, also called translucent box testing.
The table below defines the difference between white box, black box, and white box testing.

When to perform Grey Box Testing?

The use of grey box testing varies depending on the software application's requirements, testing goals, level, scope, objective, and tools. For example, it can be performed at stages like acceptance testing and system testing.
Let us see a different scenario where you can run grey box tests.
You can use grey box tests when testing the interaction between the different components of the software application. It only requires having limited knowledge of how components interact.
Whenever software applications undergo specific changes in features or updates, a grey box test should be used to verify its functionality corresponding to the changes.
You can run a grey box test when testing the security of the software applications. It is done by simulating attacks from hackers with limited knowledge of the internal working of the software applications.
Grey box tests are run to validate the functionality of the database by verifying data schema, data flow, and constraints.
You can run grey box tests in API testing. It is needed to check the functionality of the APIs and their interaction with the software applications that use them.

What to test in Grey Box Testing?

When running grey box tests, you should know about the software application's different aspects. It will help you understand the key areas that require a grey box test and give a clear path to start with it.
Here are some important aspects that you should analyze while running grey box tests:
The flow of specific inputs through the software application: Grey box testers identify and test the different inputs, such as user inputs, system inputs, or external inputs, and their source in the software application. The path through which such inputs are entered into the software application to the point they are processed and stored is traced.
Potential vulnerabilities within an application's security system: Grey box tests validates restricted actions, including accessing sensitive data, manipulating URL and input parameters, injecting code, and brute force attacks.
Testing expected output for a given set of inputs in software application: Grey box testing validates the output of a software application to ensure its alignment with the Software Requirements Specification. In other words, the tester verifies the actual output of the application with the expected output to find if there are any errors or defects. It will help ensure the software application provides the correct result, meets the end-user requirement, and functions bug-free.
Identifies poorly structured and broken code paths of software applications: QA tests the applications for the code path intended to handle errors. For this, they create test cases that cause errors to ensure that the error-handling code path is functioning as expected. Correspondingly, a tester in grey box tests checks for the complex conditional statement in an application and creates test cases that perform all possible combinations of inputs and ensure that the code path is functional in all test scenarios.
The behavior of the conditional loops: You can understand a conditional loop as a programming construct where a block of code is executed repeatedly until a specified condition becomes true. In grey box testing, you can test the behavior of the conditional loop by verifying the code to ensure the condition causing the loops and related action taken within the loop.
Test access validation: In grey box tests, verify that the user with the correct access can only perform the action for the functions or activity of the software application. For example, the grey box testers test the endpoint to ensure only admin users can make inventory changes.

Techniques of Grey Box Testing

Grey box testing can be performed during the testing phase of software application development. There are different techniques you can use to ensure all defects are addressed. Some of those techniques are as follows:

Matrix Testing

It involves creating a risk matrix to prioritize test cases depending on their severity and consequence. A score is assigned to each element or all possible combinations of inputs and parameters of the software application being tested.
Here, "element" refers to the software application's specific features, components, and aspects. For example, you can understand elements as particular functions or modules of software applications or specific user interface elements like a menu option.
The term "combinations" are a specific set of values for any input or parameters of a software application. For example, if the software application has a login function, the password and username fields are input parameters or variables, and different combinations of values are entered for these inputs.
Each element and possible combinations are evaluated based on its severity and consequence and assigned a score in the risk matrix. For this, matrix are created in the form of tables, with each row showing a unique combination of input values/elements and each column showing different parameters/elements.
The score given shows the level of risk associated with elements/combinations and allows testers to prioritize their testing efforts by emphasizing elements with high scores. With this, you can address the most critical issue first and lower the risk to the software applications. This shows different possible combinations/elements and test cases designed for each to ensure all test scenarios are covered.

Regression Testing

It is the technique where any changes or update made to the software application does not impact its existing functionality. It is utilized in grey box tests because it allows testers to identify any potential defects due to the changes done in part of their software application.
You can use the following testing strategies to perform regression testing in a grey box test:
Retest All.
Retest Risky Use Cases.
Retest By Profile.
Retest Change Segment.
Retest Within Firewall.

When you perform regression testing, you ensure the stability and reliability of software applications after the changes in the features or updates. This technique makes identifying early bugs possible in a grey box test before they cause any challenges in software application development.
You can run regression tests in automation frameworks like Selenium for your web applications. It supports different browsers and platforms for web testing.

Orthogonal Array Testing

It is a statistical testing technique utilized for selecting the number of test cases that covers a large number of combinations of input parameters/variables of software applications. The techniques of grey box tests combine statistical and exhaustive testing to give comprehensive test coverage with a minimum number of test cases.
This testing technique also covers all possible combinations of input parameters and variables by designing corresponding test cases. It is done using an orthogonal array to identify the variables/input parameters that have more impact on the function of software applications. Then you can create test cases that include all possible combinations of such variables/input parameters.
Here an orthogonal array is a set of columns. Each column has a set of values for the variables/ input parameters. When you choose a value, it should be statistically independent of each other. With this, you can ensure that each combination is covered at least once, lowering the required test cases.
Hence, you can design test cases that consider all variable/ input parameters without running many tests. Thus, this maximizes testing coverage and lowers the time and effort to run tests.

Pattern Testing

It can be performed in software applications that are developed based on a similar programming pattern or structure to previous software application projects. Some examples of patterns this test focuses on include loops, conditionals, function calls, and data structures.
The software applications are likely to have some defects that might have occurred in the previous software applications. With pattern testing, you can quickly identify the flaws in the current software applications.
This technique is used in the grey box tests to improve the efficiency of the test. Here, you can use the knowledge of the internal workings of software applications to design test cases that focus on specific patterns or structures in the code. It helps quickly identify defects related to such patterns as logical inconsistencies and coding errors.

How to perform Grey Box Testing?

There are specific steps to be followed to run grey box tests. Let us explore those steps:
Make a list of all inputs from the black and white box testing method: You need to identify all the inputs obtained from the white box and black box test. Here the inputs are the command or data given to the software application being tested. It can come from different sources like user inputs, network inputs, or automated test scripts.
Make a list of all outputs from these inputs: Once you have identified the inputs, you need to identify all the expected outputs from such inputs. For example, if the input is a user request to execute an action in a software application, the expected outputs could include completing the action, an error message if the action is not performed, or an abrupt function if the bug is present. This will help you to get the expected behavior of the software application based on its architecture, design, and specifications and give a baseline for the testing process.
Make a list of all the key routes: This involves identifying the key path or route that the software application will take during the test. You can determine this path by analyzing software applications' architecture and design or their expected functions. Here the key route may involve interaction between different software application components, such as the user interface, database, and application logic.
Identify sub-functions for deep-level testing: In this step, you need to identify the software application's sub-functions (specific parts or components of the software application) that must be tested in detail. You have to break down the software application into smaller components and test them individually to ensure their proper function. You can prioritize these sub-functions based on their importance and criticality to the software application's overall functionality.
Make a list of inputs for sub-function: On identifying the sub-function of the software application, you need to make a list of all inputs that can be used to test each sub-functions. You can get those inputs from black and white box testing.
Make a list of all expected outputs from the sub-function: For each of the inputs for the sub-function, you now need to determine its expected outputs. This will allow the expected behavior of the sub-functions of software applications.
Run the sub-function test case: In this step, you are required to create a test case or to test each sub-function individually. Each test case should be run according to specified input values and verify that the actual output matches the expected output.
Repeat steps 4–8 for each additional subfunction: Steps 4–8 are repeated for all the sub-functions identified in step 4.
Check the reliability of the sub-function result: After executing the test cases, you need to analyze the result. This is required to check whether the sub-function is working accurately or find any defects that require it to be addressed.
Perform steps 7 and 8 for other remaining sub-function: Steps 7 and 8 are repeated for all the sub-functions tested in step 9 to ensure that they meet the expected results.

Grey Box Testing Tools

Grey box testing can be performed by both manual and automated approaches. In the manual approach, testers use their partial knowledge of the design and architecture of the application to find any issues. Testers perform manual tests to overcome challenges aroused by the issue. Even though it is a time-consuming process, it is an effective approach to identifying hard-to-find bugs.
To reduce the time and effort in grey box tests, automated testing is crucial for specific repetitive tasks and components of applications accessible through APIs, SDKs, and other documentation. It uses automation testing frameworks and tools that make testing more efficient than manual testing.
Let us learn some test tools for grey box tests.
Selenium: UI test planSelenium is an open-source automation testing framework that tests web applications in browsers. You can use Selenium for cross browser testing to check the application's working across various browsers and versions.
Appium: Appium is an open-source test automation framework to test native, hybrid, and mobile web applications. You can perform automated tests with Appium on Android, iOS, and Windows platforms.
Rational Functional Tester: It is an automated functional testing tool that helps create, manage, and execute grey box tests for software applications. It also supports other testing needs like regression and data-driven testing.
Cucumber: It is an open-source testing tool supporting Behavior Driven Development (BDD). You can write tests in natural language and use a plain-text format called Gherkin to define tests. This can be done in different programming languages like Java, Ruby, Python, and JavaScript.

The tools mentioned above effectively run grey box tests, which helps ensure the quality of the software application. However, cloud-based testing platforms can leverage the use and true capability of such automation testing frameworks and tools. It offers integration of automation testing frameworks like Selenium, Cypress, Playwright, Cucumber, Appium, etc., through which you can enable organizations to deploy and manage the software applications and their infrastructure in the cloud.
For automation testing, Selenium is one of the most used frameworks for grey box testing. If you don't have to waste time and effort setting up an in-house test infrastructure, go for a cloud-based digital experience testing platform like LambdaTest.
Cloud testing platforms like LambdaTest enable testers to execute automated and manual tests of web and mobile applications across 3000+ browsers, devices, and OS. It integrates different testing frameworks which allow users to run tests on Selenium, Cucumber, and Appium on cloud infrastructure. It comes with immense capabilities and features that facilitate grey box testing.
For example, it provides an online browser farm with access to a wide range of real browsers, operating systems, and real devices. This can help devs and QA gain insight into how the website or mobile application performs across different platforms and environments.
You can also leverage LambdaTest Analytics to monitor performance and analyze test results to identify issues and improve the overall software quality.

Challenges of Grey Box Testing

Grey box testing is an important part of developing software applications that ensure their functionality. However, it has some challenges that the testers and developers should know to overcome.
When software application components under test fail due to errors or bugs, the continuing operation has to be terminated.
Grey box tests can be performed by having limited knowledge of the internal functions of the component of the software application being tested. Therefore, this may create difficulty in finding all potential defects.
Creating and executing grey box test cases is one of the great challenges. The reason is that testers need to understand the interaction between the software application's back-end and front-end components.
Maintenance efforts by the testers are often required. The reason is a change in the software application's architecture or design, which directly impacts the test cases and execution of the test.
Grey box tests require access to the source code or specialized testing tools for their success. However, such access may not be available to all testers.

Best Practices of Grey Box Testing

To overcome the challenges in grey box testing and optimize its execution in software application development, it is important to follow its best practices.
You should strive to gain a deep understanding of the software application under test, like its data flow, architecture, and back-end and front-end components. Such knowledge will help to create effective test cases and identify potential defects.
You should leverage automation tools in performing grey box tests. It will save time in testing by executing repetitive test cases.
It is always recommended to combine testing techniques like functional testing, regression testing, and exploratory testing in grey box tests. It will ensure a comprehensive test of the software application with early detection of bugs.

Conclusion

Grey box testing is one of the most beneficial software testing types that combines white and black box testing. With this, testers can access the software applications' internal workings without becoming overly biased or subjective in their testing approach.
In a nutshell, it should be noted that grey box tests are one of the most effective testing techniques that help ensure the quality and reliability of software applications. It gives a complete view of a software application's functionality and performance. This allows us to identify and fix any potential issues before releasing the software application in the market.

39 Top Python Frameworks To Look For In 2023

Nazneen Ahmad — Tue, 02 May 2023 14:59:49 +0000

When building software applications, developers typically use programming languages that align with their needs and preferences, such as Java, Python, C#, and others.

Among various programming languages, Python is becoming the popular programming language in web development and testing due to its versatility, simplicity, and readability.

According to the Stack Overflow Developer Survey 2022, Python is the fourth most used programming language by developers behind JavaScript, HTML/CSS, and SQL. This signifies 43.51% of developers use Python.

Stack Overflow Developer Survey 2022

What is the primary reason for such growing popularity? If you have used Python for web development and testing, you would have come across its vast ecosystem of frameworks built around it.

This has helped you with a set of tools and libraries that made it easier to build complex applications efficiently and quickly. Python frameworks allow developers to provide an automatic implementation of redundant tasks to lower development time.

You can focus and give more time to application logic without considering low-level details like protocols, sockets, and process management. These are the major reasons that made it highly preferable among developers. Python is likely to remain a popular language in the years to come.

When we think of Python frameworks, many names come to our minds. This often confuses us regarding which is most appropriate for software projects. However, if we look ahead to the future, what will the popular Python frameworks be in 2023?

To clear this up, I have curated a detailed list of the most popular Python frameworks for software development and software testing. You will get information on the features and benefits of these frameworks, which you should keep in mind when looking for Python frameworks.

What are Python Frameworks?
In Python, the framework is a collection of pre-written codes that gives developers a set of tools and structures to build applications efficiently. In other words, you can understand this as a collection of modules or packages that help developers build web applications. Mainly, the Python framework is a set of tools that lay the foundations for building applications, so you don’t have to start from scratch every time.

Python framework can help developers by providing the following aspects:

Standardized structure for an application that allows easy development and maintenance.
Pre-built libraries and tools help simplify common tasks like database management, form validation, and user authentication.
Security and performance, as many frameworks are designed with security and scalability in mind.
A Python framework can be either full stack, asynchronous or micro. However, before digging into the Python framework in detail, I will briefly introduce them in the below section.

Type of Python Frameworks
Python frameworks are divided into three main categories that define its specification. Here are those three Python frameworks explained.

Full Stack Framework
It comprises all web development requirements and offers all-in-one solutions. This indicates that a full-stack framework provides all features and tools needed to build web applications from start to finish. For example, it includes form generators, form validation, template layouts, and many more. Basically, this provides everything required to develop a web application, like a template engine, ORM, and admin interface.

Some popular Full-Stack Python frameworks include Django, Web2py, CubicWeb, Giotto, FastAPI, Pylons framework, TurboGears, BlueBream, and Websauna.

Micro Framework
It is a lightweight framework used for minimalistic web application development because it provides only the bare essentials needed to build them. For example, routing, request and response handling, and HTTP protocol support. Hence, this provides developers with only a minimum set of functionalities, allowing them to build lightweight and fast web applications.

Unlike a Full-Stack framework, it does not provide additional features like database abstraction, form validation, etc. However, it requires more manual work from developers. This includes manually adding other code and requirements or using third-party libraries and tools to implement the desired functionality. If you take this in a different sense, using microframework, you get more flexibility and customization options because of more control over their code.

Some popular Micro Python frameworks include Flask, Dash, Falcon, MorePath, Pycnic, and Hug.

Asynchronous Framework
Asynchronous Python frameworks allow developers to write asynchronous code, meaning the code can execute multiple tasks simultaneously without blocking other tasks. It is designed to handle a large set of concurrent connections and processes, which means managing multiple requests simultaneously without blocking the program’s execution. Using this framework, developers write codes that can be run concurrently, enabling faster and more efficient data processing.

It utilizes the asyncio library in Python, which provides a way to write asynchronous code using coroutines and event loops. Some popular Asynchronous Python frameworks include Sanic, AIOHTTP, Growler, and Tornado.

Why use Python Frameworks?
When you develop web applications or mobile apps, there are the majority of redundant operations like handling HTTP requests and responses, routing, database interactions, user authentication and authorization, input validation, and others. You always want a framework that can save time and effort in software application development. This is possible by leveraging pre-built tools and components of Python frameworks.

Python frameworks allow developers to reuse code for different tasks like HTTP operations, etc. Hence, you don’t have to re-write the code from scratch, making the development process quick and efficient.

It is easy to use Python frameworks to build and maintain software applications because it is structured in a way that allows modularity and code organization. Some standard structure features include MVC architecture, middleware, and configuration. This makes it easier for developers to understand and maintain the codebase, even as the application scales.

Below, I have curated an exhaustive list of the best Python frameworks for web development and automation testing so that you get all information in one place.

Python Frameworks for Automation Testing
Python testing frameworks are a crucial part of the web application development process that helps in testing your code to ensure it gives correct functionality. With the increase in the popularity of Python, the demand for its automation frameworks is also increasing to ensure the quality of code by automating testing tasks. This indicates that you have to choose from a huge number of Python testing frameworks where each offers automated, script-based testing that allows easy creation of test cases.

When it comes to choosing Python frameworks for testing, you have to consider the key information that defines its specificity. For example, you should look for its ability, script quality, simplicity of test cases, and other factors.

To this, I have created a list of Python frameworks for test automation in one place and explained their key features that will help to choose the right framework for your web development projects.

Robot
Robot Framework is an open-source test automation framework that simplifies writing test cases and makes them more readable and clear based on the keyword-driven approach. The thing that makes it one of the most popular Python frameworks is its specificity for acceptance testing, acceptance test-driven development, behavior-driven development, and robotic process automation.

Choosing the Right Python Framework
Development of web applications based on Python gives you various options in terms of the frameworks using which you can structure high-quality applications. However, deciding the right framework that aligns with the web project’s needs may be challenging. This is because of the availability of several Python frameworks for web development and testing with similar features.

Choosing the right Python framework requires considering factors that help you make better decisions. First, you need to be familiar with the requirements of web development projects. For example, you may ask

Are you building a small web application or a complex system that requires a lot of scalability and performance?
Do you need a highly secure framework or one that is easy to use?
If you understand the right requirement, it is easy to narrow down the list of possible Python frameworks, and among those, you can select the most appropriate one.

Another factor you should consider is around community and support offered by the Python framework. For example, is the framework widely used and well-established? Is there an active community of developers contributing to the framework and providing support? Answering such questions will give you an idea of a well-supported framework that ensures you access resources while developing and testing web applications.

You should address the Python framework’s learning curve and ease of use. Always be inclined to select a Python framework that is easy to learn and helps you get started with the testing and development process.

However, no single factor should be considered when choosing the right Python framework. Therefore, the appropriate framework will entirely depend on associated factors and the specific needs and requirements of your web development and testing projects.

Conclusion
Python will progress to remain popular among developers and testers for the release of quality web applications in 2023. The demand for web and mobile applications increases with new software technologies and methodologies. Therefore, the requirement for an efficient Python framework will increase more than ever in the coming year.
