Regression testing is a type of software testing that ensures an application continues to function as expected after any code changes, updates, or improvements. Regression testing is in charge of ensuring the overall stability and functionality of existing features.

Regression testing is a critical component of any software development process because it confirms the complete functionality after the newly added feature has been verified to be stable. It ensures that the functionality of the software continues to function as it did before the changes were made.

At Appsierra, we perform regression testing services for every code or functionality change. We create regression test suites based on business requirements, priority modules, important features, and so on, and run them during each test cycle to ensure that the system is functioning properly. We prioritise the regression test cases based on the importance of the functionalities, the frequency with which they fail, the complexity of the test cases, the test cases that cover the most recent code changes, and so on
