Sanity Testing in Software QA: Why It's a Must-Have, Not a Maybe

Testscenario — Wed, 26 Mar 2025 10:35:35 +0000

When you're patching a bug or tweaking a feature, you may not realize it—but you're rolling the dice with your app's stability. Even the tiniest change can introduce bugs elsewhere.

That's why sanity testing exists.

What is Sanity Testing?

Sanity testing is a quick verification process to ensure recent code changes haven’t broken anything important. It’s like saying: “Okay, we made a change. Is it safe to keep testing?”

It’s NOT a full regression test.
It IS a fast check of impacted areas.
It SAVES time when done right.

Why You Shouldn’t Skip It

Imagine this: You fix a bug that broke discount codes in checkout. After the fix, sanity testing would check:

Are discount codes working?
Does checkout still function?
No new issues, right?

If that test fails, why waste time running a full suite? Sanity testing helps avoid that trap.

Sanity vs Smoke Testing

Aspect	Smoke Testing	Sanity Testing
Scope	Broad, system-wide	Focused, change-specific
Goal	Is the build testable?	Is the fix working as expected?
Timing	First test after new build	After minor fixes or patches
Documentation	Scripted	Often informal

Key Traits

Performed after bug fixes or minor changes
Targets only the modified or related areas
Can be manual or automated (especially in CI/CD)
Prevents wasting time on unstable builds

When to Perform It

After bug fixes
After small enhancements or patches
Before full regression testing
As part of Agile sprints or CI/CD checks

Common Mistakes to Avoid

Skipping sanity testing altogether
Over-testing unrelated features
Running it too late in the cycle
Not documenting your sanity checks

TL;DR

Sanity testing is your early warning system.

It’s fast, focused, and fundamental for quality assurance.

Don’t skip it—embrace it.

Black Box Testing: A Developer-Friendly Guide to Methods, Types, and Best Practices

Testscenario — Mon, 24 Mar 2025 08:48:24 +0000

Black Box Testing is a staple of QA and a crucial part of delivering secure, functional, and user-friendly software. But what makes it so widely used — and how should devs and testers approach it efficiently?

Here’s a compact yet thorough guide to help you understand where Black Box Testing fits in your SDLC.

What is Black Box Testing?

Black Box Testing focuses on what the software does, not how it does it. The tester doesn’t need access to the internal code — just the requirements and the inputs/outputs.

Key Highlights:

Tests functionality without inspecting code.
No programming knowledge required.
Best suited for UI, functional, system, and acceptance testing.
Often simulates real-world user behavior.

When Should You Use It?

Use Black Box Testing during:

System & Acceptance Testing
Pre-launch QA cycles
Security & Compliance validation
Testing 3rd-party integrations

Example: For an e-commerce app, test login flows, cart functionality, payment gateway behavior, and error messages — all without needing to look at the code.

How Does It Compare?

Feature	Black Box	White Box	Grey Box
Access to Code	No	Yes	Partial
Performed By	QA/Analysts	Developers/Test Engineers	Technical Testers
Focus	Functionality	Logic & Flow	Mixed
Best For	UI, Functional, UAT	Unit, Security	Integration, APIs

Types of Black Box Testing

Functional Testing – Does it do what it’s supposed to?
Non-Functional Testing – Performance, usability, reliability.
Regression Testing – Did recent changes break something?
UAT – Is it ready for real users?
Security Testing – Can it withstand attacks?

Core Techniques

Here are the tried-and-true techniques Black Box testers swear by:

Equivalence Partitioning

→ Group inputs (valid/invalid) and test one from each.
Boundary Value Analysis

→ Test just inside/outside input limits (e.g., 5, 6, 12, 13 for a 6–12 char password).
Decision Table Testing

→ Model rules and combinations of inputs/outputs.
State Transition Testing

→ Does the system respond correctly to changes in state?
Cause-Effect Graphing

→ Map input conditions to their outcomes.
Error Guessing

→ Use experience to catch edge cases (e.g., blank fields, invalid types).
Syntax Testing

→ Test format-dependent inputs like emails, JSON, etc.
Requirement-Based Testing

→ Ensure each requirement is covered by at least one test case.
Compatibility Testing

→ Confirm behavior across devices, browsers, and OSes.

The Black Box Testing Workflow

Test Planning

Define scope, objectives, tools, and responsibilities.
Test Case Design

Use techniques like BVA and EP to generate data-rich scenarios.
Test Execution

Run tests manually or using tools like Selenium, Appium, etc.
Result Analysis

Compare actual vs expected outcomes. Flag anomalies.
Bug Reporting & Retesting

Log defects, work with devs, retest resolved issues.

Tools That Power Black Box Testing

Functional Testing

Selenium, Appium, Katalon, TestComplete

Security Testing

Burp Suite, OWASP ZAP, Acunetix, Metasploit

Performance Testing

JMeter, LoadRunner, k6, Gatling

UI Testing

Cypress, TestProject, Applitools, Eggplant

Best Practices

Start with clear requirements.
Prioritize critical user flows.
Combine manual + automation.
Use diverse data sets for robust coverage.
Collaborate with devs — especially for edge cases or grey-box needs.

Challenges to Watch Out For

Can't detect internal logic bugs.
High effort for large apps unless automated.
Harder to debug without code access.
Misses hidden edge cases unless carefully planned.

When Not to Use It

Debugging internal code issues.
Unit tests during development.
Deep performance profiling or memory leak detection.

Final Thoughts

Black Box Testing is essential to ship software that works for users, regardless of what’s under the hood. It ensures reliability, functionality, and security — and fits perfectly into agile, CI/CD, and automation-first pipelines.

Key Phases of the Performance Testing Life Cycle

Testscenario — Thu, 20 Feb 2025 11:15:49 +0000

In today’s digital landscape, software performance is a critical factor in determining the success of an application. Slow response times, system crashes, and scalability issues can lead to poor user experience, loss of revenue, and reputational damage. To prevent these problems, organizations implement Performance Testing, a specialized type of testing that evaluates an application’s ability to perform under various conditions.

However, performance testing is not a single-step process—it follows a structured Performance Testing Life Cycle (PTLC) to ensure systematic evaluation and optimization. This life cycle consists of multiple well-defined phases, each contributing to identifying, analyzing, and improving software performance before it reaches production.

This article explores the key phases of the Performance Testing Life Cycle, detailing how each stage plays a vital role in ensuring application reliability, scalability, and efficiency.

1. Requirement Gathering & Performance Benchmarking

The first phase in the PTLC involves gathering performance-related business and technical requirements. This stage is crucial because it sets the foundation for designing realistic test cases and defining measurable success criteria.

Some key aspects considered in this phase include:

Expected number of concurrent users
Peak traffic conditions
Page load time requirements
Transaction response time expectations
Maximum throughput and resource utilization limits

Defining Key Performance Indicators (KPIs)

Performance KPIs help teams establish benchmarks that indicate whether the application meets expected performance standards. Some common KPIs include:

Response Time: The time taken by the system to process a request.
Throughput: The number of transactions processed per second.
CPU & Memory Utilization: The percentage of system resources consumed during load.
Error Rate: The percentage of failed transactions due to system bottlenecks.

At this stage, it’s also important to identify the type of performance testing needed, such as Load Testing, Stress Testing, Scalability Testing, Endurance Testing, and Spike Testing.

2. Test Planning & Strategy Development

Once performance requirements are defined, a comprehensive test plan is developed. The performance test plan outlines:

The scope of performance testing (components to be tested)
Test scenarios (realistic user interactions to simulate)
Testing schedule and timelines
Required test environments (hardware, software, network configurations)
Performance testing tools (JMeter, LoadRunner, Gatling, Locust, etc.)

Designing Test Scenarios

Test scenarios should closely replicate real-world usage patterns to provide accurate performance insights. Some examples include:

Simulating a checkout process on an e-commerce platform.
Testing login attempts with multiple concurrent users.
Measuring API response time under a high load.

The objective is to design scenarios that reflect expected and peak user loads, enabling testers to measure system behavior in normal and extreme conditions.

3. Test Environment Setup

Performance tests must be conducted in an environment that mimics production as closely as possible. Differences in configurations, infrastructure, and database sizes between the testing and production environments can lead to misleading results.

Key elements of a performance test environment include:

Hardware setup: Servers, load balancers, network devices.
Database configurations: Data volume and indexing strategies should match production.
Third-party integrations: Ensuring all external services used in production are available during tests.

Cloud-Based Performance Testing

Many organizations use cloud-based solutions for scalable performance testing. Cloud platforms (AWS, Azure, GCP) allow testers to simulate thousands or even millions of concurrent users without requiring extensive infrastructure investments.

4. Test Script Development

Performance test scripts are designed to simulate user behavior and interactions with the system. Scripts should include:

Dynamic data handling to simulate real-world scenarios.
Parameterization for testing different input values.
Correlation techniques to handle dynamic session variables in web applications.

Choosing the Right Scripting Approach

Some common scripting approaches include:

Protocol-Level Scripting: Simulates network requests without a UI (e.g., REST API tests).
UI-Based Scripting: Interacts with the application through front-end components (e.g., Selenium-based load tests).

Automating scripts ensures repeatability, efficiency, and consistency in performance testing.

5. Test Execution & Monitoring

Once scripts are developed, actual test execution begins. Different types of performance tests focus on various aspects of system behavior:

Load Testing: Measures system performance under expected workloads.
Stress Testing: Pushes the system beyond its capacity to determine its breaking point.
Endurance Testing: Evaluates system stability over an extended period.
Scalability Testing: Determines how the system handles increasing loads.
Spike Testing: Analyzes system response to sudden traffic surges.

Monitoring System Performance in Real-Time

During test execution, real-time monitoring tools like New Relic, Datadog, or Dynatrace help track:

CPU, memory, and disk usage
Database query performance
API response times
Error rates and system crashes

This data provides insights into potential performance bottlenecks and areas for improvement.

6. Performance Bottleneck Analysis

After test execution, collected data is analyzed to identify performance issues. Some common bottlenecks include:

Slow database queries causing response delays.
Memory leaks leading to excessive RAM consumption.
Unoptimized APIs increasing server load.
Poorly managed thread execution causing deadlocks.

Using Application Performance Monitoring (APM) Tools

APM tools help pinpoint specific performance issues by providing detailed logs, heatmaps, and error tracking. The goal of this phase is to identify root causes and develop optimization strategies.

7. Optimization & Re-Testing

Based on the analysis, developers and DevOps teams work on:

Optimizing database queries (e.g., adding indexes, query caching).
Enhancing server-side processing efficiency (e.g., reducing computation overhead).
Refining load balancing strategies (e.g., distributing traffic efficiently across servers).
Improving application caching (e.g., CDN implementation for static assets).

Re-Testing for Validation

After optimizations are made, performance tests are re-run to validate improvements. The process continues iteratively until the application meets performance benchmarks.

Conclusion

The Performance Testing Life Cycle (PTLC) ensures that applications meet performance expectations before reaching users. By following a structured approach—from requirement gathering to test execution, analysis, and optimization—organizations can:

Prevent costly post-release failures.
Ensure a smooth user experience.
Enhance application scalability and reliability.
Improve development efficiency with early performance testing integration.

In today’s fast-paced software development landscape, proactive performance testing is no longer optional—it is a necessity for delivering high-quality applications that meet modern user expectations. By integrating performance testing into Agile, DevOps, and CI/CD workflows, organizations can ensure their software performs optimally under all conditions.

How to Test Applications with External APIs: Strategies and Solutions

Testscenario — Fri, 24 Jan 2025 10:58:22 +0000

Modern app development relies heavily on external APIs for critical functionalities like payments, authentication, and messaging. Services such as Stripe, Auth0, and Twilio simplify app development, but they also come with challenges—especially when it comes to testing.
Third-party integrations can introduce risks, such as unexpected failures or incorrect responses. Without proper testing, these issues could disrupt your app's functionality and user experience.
This guide explores the challenges of testing third-party APIs and provides actionable strategies to ensure your integrations are reliable, secure, and performant.

Why Testing Third-Party APIs Is Essential

Gone are the days when developers had to build everything from scratch. Today, APIs offer ready-made solutions for almost every need. However, relying on services you don’t control means you’re exposed to risks:

Unreliable responses: APIs may fail or behave unpredictably.
Security vulnerabilities: Poor testing may expose sensitive data.
Increased maintenance: API updates can break your integrations.

Testing ensures your app interacts seamlessly with these APIs, even when conditions change. It’s not just about catching bugs—it’s about building confidence in your app’s stability.

What Happens When You Don’t Test APIs?

Skipping API tests or relying on unreliable methods can lead to unexpected issues. Here are three common (and problematic) approaches to testing APIs:

1. Skipping Tests Altogether

Many teams delay API testing, thinking it’s a low-priority task. Some even write tests but abandon them when they become unreliable.

Why This Fails:

Unpredictable behavior: You won’t know if the API suddenly changes or fails.
Missed bugs: Critical issues may slip through and affect production.

2. Testing with Live APIs

Testing against real APIs might sound practical, but it’s fraught with risks. Consider these scenarios:
Unexpected side effects: Making real API calls in testing environments can lead to unintended actions, like sending real messages or modifying live data.
Slow execution: Real API tests depend on network reliability, making them slower.
Security risks: Exposing API keys in testing pipelines can result in data leaks or misuse.

Example Mishap:
A company once embedded a real API key in their test environment. The result? Thousands of unwanted text messages were sent to a random individual, creating a costly and embarrassing situation.

3. Building Mock APIs Manually

Some teams attempt to avoid live API risks by creating mock versions of APIs. While this approach is safer, it’s also time-intensive and hard to maintain.

Challenges with Manual Mocks:

Mocks can quickly become outdated if the API changes.
Writing and maintaining detailed test scripts is tedious and resource-heavy.

Effective Strategies for Testing API Integrations

To ensure reliable and efficient API testing, consider these proven methods:

1. Use Mocking Tools

Mocking tools replicate the behavior of real APIs without making actual network calls. They allow you to simulate responses, test edge cases, and control test conditions.

Benefits of Mocks:

Faster test execution.
No reliance on network availability.
Easy simulation of error scenarios (e.g., 500 server errors).

Popular Tools:

Nock: Ideal for mocking HTTP requests in Node.js projects.
WireMock: A flexible library for stubbing and mocking APIs.

Key Tip: Focus on mocking only the behaviors you need to test. Avoid over-engineering your mock API, as maintaining it can become a burden.

2. Automate API Testing with Specialized Tools

If writing and managing mocks feels overwhelming, automated testing tools can streamline the process. These tools generate and execute test cases based on your app’s API interactions, saving significant time.

Why Use Automated Tools:

Reduced manual effort in creating test cases.
Continuous testing even when APIs evolve.
Coverage for scenarios you might overlook manually.

Example Tool:

Postman: Allows you to automate API testing and monitor responses.
Pact: Supports contract testing, ensuring your app and the API are always in sync.

3. Monitor and Test in Production

For mission-critical APIs, consider implementing monitoring systems to test the integration in production environments. This ensures real-time visibility into API health and response times.

Best Practices for Production Testing:

Use synthetic monitoring to test APIs at regular intervals.
Set up alerts for unexpected responses or failures.

Best Practices for API Testing Success

To maximize your testing efforts, keep these best practices in mind:

Secure your tests: Never expose API keys or sensitive credentials in your test environment.
Test edge cases: Simulate network failures, slow responses, or unexpected data formats.
Stay updated: Regularly review API documentation and changelogs to ensure your tests remain relevant.
Automate where possible: Reduce manual workload by leveraging tools that handle repetitive tasks.

Conclusion: Test Smarter, Not Harder

Testing third-party integrations isn’t just a technical task—it’s a safeguard for your app’s reliability and user satisfaction. Whether you choose mocking tools, automated testing platforms, or a combination of both, the goal is to build confidence in your app’s interactions with external APIs.
By investing in proper API testing strategies, you can deliver robust apps that stand the test of time, no matter how APIs evolve.

The 15 Things You Should Include in Your App Launch

Testscenario — Fri, 03 Jan 2025 09:15:38 +0000

If you are in search of an app launch checklist, this blog is the right one for you.

After building your app, investing all that money or even time, you need to release it in the app store but you are in the dark regarding what to do and where to begin, and what should be done to make sure that your app surfaces when a user is searching for a related query.

Rather than getting a build rejected, or failing in the already competitive app world, it’s always safe to have a look at this checklist.

Here it is,

1) Perform testing and ensure a robust product

Do you think that you have created an impeccable product? If you do, the thought itself is very dangerous before proper assurance.

The way you are using the app or your entire team is using the app might not be the way the user is interacting with it. Next would be the security of the app.

You are dealing with sensitive user data and it has to be safeguarded at any cost.

Performance of the app also has utmost value because at present since app crash serves as one of the major uninstall reasons.

Another one is to evaluate the functionality of the app with respect to the SRS document and ensure that everything is working as per the definition.

You also need to also check the usability of the app to make sure that it offers a high user experience for those who are using it.

Not sure where to start with mobile app testing? Don’t worry; connect with testscenario to ensure you get a high value mobile app testing team.

2) Market research

You have developed an app that can track trains across the country. Good thought!

Even though you are aware of the competition you proceed to release the app. What will happen? There is a high chance that it sinks into the deep abyss of the app world and would max attain a few hundred installs or maybe less, or more.

What do you gain from it? Nothing! All your hard work goes in vain.

So before launch, you need to do extensive market research with these questions in mind,

What’s it that people are asking for the most in the competitor apps review section.
What’s that one or a bunch of features that have made your competition apps successful?
What’s the prime reason for a certain query that makes all the competitor apps visible.
Do you think that your app has some uniqueness compared to the existing competition. If you think that you have answers to all these questions, you have a good product. But. no, it has not yet met the preconditions for release.

3) A landing page for your app

You have released an app in the store, how do you ensure that the right people are using it?

Or, how can you make people understand the app features to their full extent? In short, how can you just rely on the app store to magically present your app in front of users?

This is the reason why you need a kick-ass landing page,

Other benefits include,

Lure users into your landing page using paid ad campaign, social media, or even SEO, BAM! You get conversions just like that.
Increase your trustworthiness! Landing pages will have a positive impact on users’ minds, your authenticity can be expressed and felt by them easily.
Landing pages help greatly in branding. You can bring all the style elements into the landing page and tell the story of your app in detail.
Landing pages provide extensive data such as user demographics, requirements, etc.

4) Push and social notifications

It’s a known fact that most mobiles are ridden with apps that users rarely use. For them to access it has to be either something that they daily use or they have to be reminded through some sort of notification.

Witty notifications about offers or features of the app will surely persuade a majority of the app users to open it and use it.

And also, social media integration and running paid ads will increase the chances of users coming across it.

5) App analytics is a boon

App launch helps is cardinal in measuring the success of the app. Through app analytics, you can evaluate the value of your app and increase it for better ROI. Here are other uses,

Helps in analyzing user behavior and diverse data that can be used to enhance the app through future updates.
The diverse information analytics contain include, which feature engages the most, user base ( daily, weekly and monthly) active devices, retention rate, other KPIs, etc.
Data generated by analytics can be used for personalized experiences.
Helps in forming realistic marketing goal.

6) An auspicious Launch date?

Just kidding! There is no such thing as an auspicious launch date. However, it’s better that you release your app on Wednesday or Thursday.

The reason is simple. It’s not wise to release your app at the end of the week since it can encounter many issues after release. Correcting it at the weekend might be a tough task.

7) Videos. They speak volumes

A demonstration video is very important since it’s the most powerful medium than text.

You can talk about the important features of the app as well as include marketing elements in it.

However, you need to limit the video to minimum duration and ensure that you have incorporated tutorials for the app operation.

8) Use social media

Social media without a doubt is the most engaging type of app in existence. Social media platforms can be used for driving organic traffic and as well for executing paid ads.

However, you need to have an official page for the app a month before the release to ensure proper branding and to build a user base.

Doing paid ads to drive users, is indeed a good thing. You can also use social media and use other forms of content to channel users to your page.

9) Deep linking for a better installation rate

Deep links will lead users directly to the app installation page removing all the boring usual steps ahead.

If you have a new offer or even a promo code you can embed the deep link into any type of promotional notification or page and lead users directly to the app installation page of the respective app store.

Deep links play a crucial role in the conversion rate and the best part is that they can be tracked using analytics.

Also, a single deep link will be enough for both iOS and Android phones.

10) ASO and SEO is the way

ASO is a content optimization activity performed to make sure that your app is surfacing when the user is searching for a certain query in app stores. On the other hand, SEO will ensure that your app gets indexed and rank higher when a user searches for it in the search engine.

Some of the techniques you can use are that

Selecting the keyword wisely, if you are going for a keyword that has high competition it’s better to look for others and incorporate them into your content. Make sure that the keyword is added inside the description of your app.
Do not just focus on one keyword. Incorporate related keywords as well use deep-linking.
Use long-tail keywords.
Incorporate keywords into the meta-description itself.
Optimize your screenshot and videos before uploading.

Checklist to make sure that your app is not getting rejected

Make sure that your app content does not have anything sensitive in it.
Make sure that your app is not an exact copy of similar ones.
Ensure that the layout of your app is optimized and it wil run smoothly on both the platforms. Using an adaptive layout is the best way.
Explaining your privacy policy in detail is a must.
Explain in detail regarding data protection and usage policy.
Unravel potential bugs and performance issues through third-party beta testing.
Check the loading time of the apps and ensure a fast-loading app.
Make sure that there are no broken links.
Do not put dummy content.
The metadata of the app should be complete.

Some crucial extra points

You can optimize the code of your app using tools such as proguard, guardsquare, dirask, etc.
Optimize your image using tools like optiPNG, PNGcrush, etc.
Avoid using too many .Jar libraries.
Use vector image as it is lesser in size.
Try to optimize your layouts.
Try to design a better preference window rather than the usual boring one.
User test the app.
Go for a keyword-based app name.
Include a help section in your app that can explain all the functionality and features.
Create a simple yet creative icon.
Try to improve your ASO after a lot of research.
Incorporate rating suggestions a particular sections of the app.
Use emulators to test your app.

Conclusion

Technical knowledge would not suffice in a successful app. You need to make sure that you are releasing a robust product in the app store that’s technically good and with all the optimization and marketing strategies implemented into it.

Hope the points listed above can help you in achieving such a good product capable of superb market penetration.

If you need someone who has done this a lot to test your app, you can contact us for testing. We will ensure that your hard work will not go in vain.

What is Regression Testing?

Testscenario — Tue, 20 Aug 2024 11:05:22 +0000

In the ever-evolving landscape of software development, maintaining the stability and functionality of applications is crucial. As new features are added, or bugs are fixed, it's essential to ensure that these changes don't inadvertently introduce new issues. This is where regression testing comes into play. In this blog, we’ll delve deep into the world of regression testing, its importance, methodologies, and how it can help you maintain the quality of your software. We'll also explore how our company, Testscenario, can assist you in implementing effective regression testing strategies.

Understanding Regression Testing

What is regression testing?

Simply put, regression testing is a type of software testing that ensures that recent code changes have not adversely affected existing features. The goal is to confirm that the software continues to perform as expected after modifications like bug fixes, enhancements, or configuration changes.

In the context of Agile and DevOps, where continuous integration and continuous delivery (CI/CD) are prevalent, regression testing becomes even more critical. It allows teams to ensure that the frequent updates and iterative changes do not compromise the software’s quality.

Why is Regression Testing Important?

Regression testing is vital for several reasons:

Maintains Software Stability: With each new update, there's a risk that existing features might break or malfunction. Regression testing helps identify such issues early, maintaining the overall stability of the software.

Enhances Customer Satisfaction: High-quality software leads to satisfied customers. By preventing bugs from reaching production, regression testing helps in delivering a product that meets customer expectations.

Cost-Effective: Detecting and fixing bugs early in the development cycle is far more cost-effective than addressing them post-release. Regression testing helps in identifying issues before they escalate.
Supports Agile Development: In an Agile environment, where development is iterative, and changes are frequent, regression testing ensures that new code integrates well with the existing codebase without introducing new defects.

Types of Regression Testing

There are several types of regression testing, each suited to different scenarios:

Corrective Regression Testing: This is used when there are no changes in the product's code, but the testing process is repeated. The objective is to ensure that the previously fixed issues have not reappeared.

Retest-all Regression Testing: In this approach, all the tests in the test suite are re-executed to ensure that no functionality is broken. Although thorough, this method is time-consuming and resource-intensive.

Selective Regression Testing: Instead of retesting the entire application, only a subset of the test cases is executed. These test cases are selected based on the impact of the code changes, making it a more efficient approach.

Progressive Regression Testing: This type of testing is conducted when there are significant changes in the code. It helps to ensure that the new changes do not impact the existing functionality.

Complete Regression Testing: This involves testing the entire product from scratch. It is usually performed after significant changes, such as a major version upgrade, to ensure that the product works as expected.

Regression Testing Process

The regression testing process typically follows these steps:
Identify Changes: Start by identifying the parts of the code that have been modified. This helps in determining which tests need to be executed.

Select Test Cases: Based on the changes, select relevant test cases that need to be executed. This selection can be automated using tools that track code changes and suggest corresponding test cases.
Prioritise Test Cases: Not all test cases are equally important. Prioritise test cases based on the criticality of the features they test and the likelihood of defects.
