What is Acceptance Testing? Types and Examples

kirankumarpaita — Wed, 25 Nov 2020 07:14:45 +0000

Acceptance Testing
Acceptance Testing is the final level of software testing. The main aim of this testing is to determine the working process of the system by satisfying the required specifications and it is acceptable for delivery. It is also known as End-User Testing. It also works under the Black Box Testing Method.
User Acceptance Testing (UAT)
The name itself says that it is from the user point of view. It helps to determine whether the system is working for the user with the given specific requirements. Here, the user refers to whom the system is going to handle after completion of all the testing levels. Usually, customers or customer’s customers will perform this testing.

Business Acceptance Testing (BAT)
It helps to check whether the system satisfies the business requirements and specifications. The main aim of this testing is to help in increasing business profits by considering market strategies and technologies.

Contract Acceptance Testing (CAT)
The name itself says that it helps to test the product with all acceptance test cases within the contract period of time. The contract may be like payment will be done before the product goes live or after the product goes live.

Regulation Acceptance Testing (RAT)
If testing undergoes all the rules and regulations that are released by the government then it is said to be RAT. Not even a single violation has not to be found while performing this testing if any occurs then the whole product will be going under failure. So, it is the most important and complicated testing type.

Operational Acceptance Testing (OAT)
This testing mainly used to determine the product’s compatibility, reliability, stability, etc., before it is going to live.

Alpha Testing
Specialized Testers will perform this testing to check any bugs have occurred. Also, they help to give suggestions to improve product usability in a controlled manner.

Beta Testing
Beta Testing helps to grab the bugs or any issues of a product. End-Users will perform this testing with an uncontrolled manner.

Best Example to understand this testing
During the process of manufacturing a mobile phone, there are so many parts like a camera, speakers, flashlight, buttons, display, headset, charger, etc., will be produced separately by different manufacturers.
All these parts will first go under unit testing
After unit testing, they go for integration testing.
Later, system testing will be performed
Finally, acceptance testing will be performed before it is out for delivery.
Types of Acceptance Testing
The most important seven types of this testing are

What is Unit Testing? Unit Testing Tools and Types |

kirankumarpaita — Fri, 20 Nov 2020 07:44:56 +0000

Unit Testing
The process of testing the individual units of software is called Unit Testing. It will be done during the development of a software application. According to the programming procedure, a unit may be an individual function of the software.

Unit Testing is one of the levels of software testing and usually done by the developer. It is the first level of testing. Developers or QA Engineers will handle this testing.

Working Process of Unit Testing
With the help of this testing, we can fix bugs or errors during the development cycle
It enables developers to make changes quickly and saves cost
It helps to get a good quality software product
Unit Testing Types
It is of two types namely Manual or Automated.

Most probably performed by manually but developers always prefer to do automation testing. It is a white box testing technique comes under following test coverage techniques

Branch Coverage
Condition Coverage
Decision Coverage
Statement Coverage
Using White box testing methods
Test cases can be derived that all independent paths within a module have been exercised at least once.
Exercise all logical decisions on their true and false sides.
Executes all loops at their boundaries.
Exercise internal data structures to assure their validity.
Unit Testing Tools
JTest
JUnit
NUnit
JMockit
EMMA
PHPUnit
xUnit.net
TestNG
QuiltHTTP
HTMLUnit
EmbUnit
SimpleTest
ABAPUnit
TypeMock

Karma
Jasmine
Mocha
Parasoft
Advantages
Developers will be able to understand the functionality of the Unit API
It helps the developers to rewrite and modify the code anytime and ensure the unit works as usual
It helps to test each and every unit of the software application so that named as Unit Testing
Disadvantages
It is very complicated to test each and every unit in large scale programs as it takes a lot of time
There may be a chance of missing units or paths of code in trivial programs
It allows testing only certain units or paths of code so that we are unable to grab the integration errors

What is Integration Testing? Types, Tools and Strategies

kirankumarpaita — Thu, 12 Nov 2020 09:06:12 +0000

Integration Testing
The process of testing the combination of units or integrated units of a system or product is called Integration Testing. It is the second level of software testing and helps to test the multiple modules of software written by different level of programmers. It is also said to be String Testing or Thread Testing. Also one of the levels of testing usually performed by developers or software testers.

Working Process of Integration Testing
The initial step is to prepare the tests plan
To design the test cases, test scenarios and test scripts
To execute the test cases
Optimize the test cases
To perform re-testing to ensure that the system is defect-free
Integration Testing Types/Strategies/Approaches
There are 4 different testing approaches namely

Big Bang Approach
Top-Down Approach
Bottom-Up Approach
Hybrid/Sandwich Approach
Big Bang Approach:
Big Bang Approach is nothing but testing by combining all the functional units at the group. This approach will take place after receiving the software at once.

Top Down Approach
Here top-level units are going to be tested first later lower level units will be tested one by one. This approach takes help of Test Stubs to perform testing on lower level units

Bottom Up Approach
It is quite opposite to the Top-Down Approach. This approach takes help of Test Drivers to perform testing on top level units

Hybrid/Sandwich Approach
This approach is the combination of both Top-Down and Bottom-Up Approaches. Here top-level units and lower level units are tested. It takes the help of both test stubs and test drivers

kirankumarpaita — Tue, 03 Nov 2020 05:07:46 +0000

System Testing

The process of testing the complete and integrated software product to meet specified requirements is said to be System Testing. The main aim of this testing is to test the whole software product which is already integrated. It is the third level of software testing. Independent software testers will perform this testing.

Working Process of System Testing

Initially, it will perform testing on fully integrated applications to verify that the interaction is made perfect with the application.
To Optimize each and every input of the application or product to get the expected output
Finally, make sure that the application got the desired output which will be ready for the final level of testing
Types of System Testing
It is broadly divided into two types namely Functional Testing and Non-Functional Testing

Again Functional Testing is divided into many types

Acceptance Testing
Beta Testing
Integration Testing
Interface Testing
Regression Testing
System Testing
Sanity Testing
Smoke Testing
Unit Testing
Non-Functional Testing is also divided into many types

Methods of System Testing
According to software testing, there are 3 methods of testing available namely

Black Box Testing
White Box Testing
Grey Box Testing
Among these three methods, this testing will come under the Black Box Testing Technique

Advantages

It performs testing on end-to-end scenarios of the system
This testing helps to determine the errors or bugs before the product goes live
It helps in testing both application and business requirements

Disadvantages

As it needs to test the whole system it requires a lot of time
Depending on the business requirements and application architecture cost may also increase

Top 5 Major Benefits of Cloud Testing

kirankumarpaita — Mon, 26 Oct 2020 07:04:58 +0000

Here is the list of top 5 major benefits of cloud testing and their performance showcase on our business growth which allow testers to increase computing resources according to their needs.

24 Hour Access to the Resources
The resources are promptly accessible for testing round the clock for numerous groups. The groups are often present in numerous time zones or in numerous corners of the globe and might still access the information that was established within the cloud-based resources. 24-hour access would mean that the testing cycle of associate degree application can ensue endlessly with none interruption

Cost Effective
The ownership in the cloud is based on automation tools and resources. The tools and resources that are used in the cloud are not very expensive. Less expenditure on the tools denotes that less capital expenditure. The tools once bought are reusable. The organization pays for the tools as and when they are required. No extra cost is paid if the tool is not being used in a given testing application.

Consistent Development Tools Setup for Existing and New Staff
With cloud-based testing, it is easy to share the data and tools. Every time a new member joins the team, one does not have to reinstall everything for him since everything would be readily available and all have to do is join the team and contribute his work.
Benefits of Virtualization
Cloud uses such tools that help bring in benefits of virtualization. It helps the firms to make use of their resources in the most efficient and optimized manner. The applications are becoming complex day by day and hence virtualization helps to reduce the costs.

Reduced IT Management Effort
Since cloud-based tools are better compared to manual testing, the cloud tools reduce the efforts and time of IT management like installation, upgrades for software globally, licensing. Since the management has minimal work to do, they can concentrate on other activities and give in their best in other fields too.

Difference Between iOS and Android Testing

kirankumarpaita — Tue, 13 Oct 2020 07:32:35 +0000

Even though there are different types of operating systems are there, iOS and Android are the most used operating systems in the world. The major differences between iOS and Android testing along with some important mobile app testing tools are shown below.

iOS Mobile App Testing Features

iOS apps can be downloaded from apple’s digital platform i.e. App Store only
As there are very less number of iOS devices are there, the testing process will take very less time
The iOS is developed by Apple and they understand their design. So, testing is as there is only one manufacturer
The iOS capacity planning is not complex but necessary
iOS is a closed-source operating system and uses the XNU kernel
iOS users can install the updates on all iOS devices at once as there is only one manufacturer
There are only a few numbers of devices with resolutions compared to Android devices

Android Mobile App Testing Features

Android apps are able to download from the Google Play Store and from some other websites too
There are a large variety of Android devices available. Hence, the testing process will take a long time
Android devices are available from various manufacturers that have different design and functionalities to test all of them is crucial
The capacity planning is crucial for Android as there are many Android devices
Android is Google’s open-source operating system and uses mostly Linux OS
The updates for Android take a long time to be available depending on various devices and their manufacturers
Due to a large number of screen sizes and layouts, screen resolutions are also different which increases the chances for bugs and errors

Mobile App Testing Parameters for both iOS and Android

System Type

Ios is a closed-source operating system developed by Apple. It uses XNU kernel built-in C/C++ and Objective C. Whereas Android is an open-source operating system developed by Google with the help of Linux OS built-in C/C++. Hence mobile app testing process is easy for iOS devices while compared to Android.

Types of Devices

As there are a large variety of Android devices are there, so the mobile testing process will go under longer deployment process, whereas iOS consists of only one manufacturer the deployment process will be done within a short period of time

Software Upgrade

For Android devices, manufacturers will be different depending on the type of device. Hence whenever a software update got released there is no chance of upgrade for all Android devices at once. Whereas iOS has only one manufacturer all iOS users can upgrade their devices at once. Here testing is easy for iOS devices as there is only one manufacturer and one design coming to Android it is difficult to test all functionalities and design as it contains a different type of manufacturers.

Screen Resolution

As there are plenty of varieties in screen sizes and layouts for Android devices the testing process will be difficult whereas most of the iOS devices screen resolution and functionalities will be similar so that testing will be very easy

App Stores

As iOS contains only one manufacturer called Apple, iOS apps are able to download only on the App Store. Whereas Android apps are available from Google Play Store and some external websites too. In this case, it is crucial to test Android mobile apps compared to iOS apps.
