What is the difference between regression testing and retesting

Question

Accepted Answer

Regression testing is testing the entire application after changes, while retesting is testing a specific bug fix.

Regression testing involves testing the entire application to ensure that new code changes have not affected existing functionality.
Retesting involves testing a specific bug fix to ensure that the issue has been resolved.
Regression testing is typically done after every code change, while retesting is done after a bug fix.
Regression testing helps ensure that new features do not break existing functionality, while retesting ensures that a specific issue has been fixed.
Example: After adding a new feature to a website, regression testing would be done to ensure that all existing features still work. If a bug is found in the new feature and fixed, retesting would be done to confirm the fix.
