Regression testing is a critical part of software maintenance. It tests software application to ensure that its function hasn’t changed after a code has been changed or added to the application. Its purpose is to ensure that application works fine with the new functionality, error fixes or any updates made to the existing feature of the application. Previously executed test cases are re-executed to validate the impact of the change.
Regression testing can be used not only for testing the accurateness of a program, but also to track the quality of its output. Regression tests are broadly categorized as functional tests or unit tests. Functional testing tests the complete application with its various outputs. Unit tests exercise individual functions or object methods.
