Code changes or improvements or updates are common practices performed for web, desktop, and mobile applications. Every time the application undergoes changes, the better it becomes and also requires the regression testing. 

Regression testing is the testing process that helps to verify if the code changes in the software have not resulted in any impact on the existing features and functionalities of the product. This process effectively helps in ensuring a proper workflow of the software system. Thus, to ensure this testing process is more efficient, teams have to select the right regression test cases by following certain guidelines.

Enterprises often plan to advance the application in order to improve the app quality and enhance user satisfaction. When a new update or change is made to the application, there is a major need for the testing teams to perform regression testing. 

Yes, regression testing is one of the functional testing types that helps in verifying if the changes made to the code have not impacted on the already existing functionalities of the application.

Regression testing is a very essential testing process to ensure the app is working fine even after changes made. If this testing process is neglected, then this can terminate the complete workflow of the system and affect the goodwill of the organization. Thus, it is vital for the QA teams to perform regression testing by following certain crucial tips in selecting the test cases for regression testing.

<h1><b>What is Regression Testing?</b></h1>

Regression testing is one of the software testing processes that helps to validate if any changes or modifications made to the software have not affected the already existing features and functionalities of the application.

This testing process has crucial importance in the software development lifecycle (SDLC) as it helps in ensuring that the core functionalities of the application are unaffected when there is addition of new features.

<b><h2>What are the 5 major Tips for Selecting Test cases for Regression Testing?</h2></b>

<b>Choose Test cases with Frequent Bugs and Defects: </b>

While planning to perform <a href="https://www.testingxperts.com/blog/regression-testing">regression testing</a>, test engineers have to choose the test cases where are there are more frequent defects or bugs. Even a small change in the code can affect the software and result in multiple issues, thus make sure to select the test cases that are having frequent bugs.

<b>Select the Test cases with recent changes: </b>

Regression testing comes into action only when there is a change made. Hence, always choose the test cases with modifications made in the code or application functionality. Also, while choosing, ensure to select the test cases even with small changes because even the minute can affect the complete system functionality.

<b>Choose the test cases based on the impact of the bugs: </b>

When the impact of fixing the bugs is low, then testers can select the high priority test cases for the impacted functionalities. But, if the criticality for the bug fixes is very high, then it is essential for the teams to choose all the test cases including high, medium, and low.

<b>Select the test cases validating the core functionalities: </b>

Before planning for test cases, the most important step is identifying the core functionalities of the application. The core functionality test cases must include all the functionalities as stated in the requirement document. Also, make use of the traceability matrix so that it helps in assuring all the main requirements are tested.

<b>Consider all integration test cases: </b>

Though integration testing is a different testing process from regression testing, it is important to include integration test cases in the regression test suite. This will help in eliminating the integration issues in the interfaces, i.e. data transferring issues from one module to another module.

<b>Conclusion:</b>

Regression testing is a crucial testing process in SDLC, especially for agile approaches. Almost every enterprise around the globe is now shifting towards agile development methodology and this is ultimately driving more importance to regression testing. Considering regression testing in agile helps the development teams in validating every new functionality and assures the software is continuously tested after every modification. 

Thus, to make this <a href="https://www.testingxperts.com/blog/regression-testing">regression testing process</a> more efficient, it is vital to consider certain tips as mentioned above. Leverage regression testing services from next-gen QA testing services provider to ensure the changes made in the code are not affecting the system.
