Regression Testing is a software testing process that verifies if recent code changes have not adversely affected existing functionality. It ensures that modifications or enhancements to the software do not unintentionally introduce new bugs or issues into previously working features.
The primary purpose of Regression Testing is to maintain the integrity and stability of the software application after code changes. It aims to identify and fix defects that may have been inadvertently introduced during development, ensuring that the software continues to perform as expected across different versions and updates.
Regression Testing works by re-executing test cases that cover critical areas of the software impacted by recent code changes. Testers systematically validate whether all existing functionalities still work correctly and that no new bugs have emerged. It involves running automated tests or manually testing specific scenarios to detect regressions.
Regression Testing offers several benefits:
In software development, Regression Testing plays a crucial role in maintaining software quality and reliability by verifying the continued functionality of existing features after changes are made. By conducting thorough Regression Testing, teams can mitigate risks, deliver more stable software releases, and enhance user satisfaction.
