In the fast-paced landscape of rapid software development, where upgrades and modifications are frequent, it is crucial to ensure the stability and quality of software products. Regression testing plays a vital role here.
Regression testing is a fundamental testing process that consists of repeated testing of the existing features of any tool, application, or system as it receives new upgrades. Testers conduct regression tests to ensure that an application’s live and new functionalities remain working and undamaged. Under this testing approach, the quality analyst checks existing features’ functional and non-functional aspects to ensure no new bugs or errors in the application.
Running regression tests is more than just re-running previous test cases; it ensures that new functionality is compatible with the existing ones without breaking the system now or in the future.
