Regression Testing is a type of software testing that ensures recent changes have not adversely affected existing functionalities. It focuses on detecting defects introduced into unchanged areas of the software after updates or modifications have been made.
Key Aspects:
- Verifying that previously developed features still work as intended.
- Ensuring that new code changes do not disrupt existing functionality.
- Identifying unintended side effects caused by recent updates.
Regression testing can be performed manually or automated using testing tools. Regular regression testing is essential for maintaining software quality throughout its lifecycle.
