Difference between Retesting and regression testing?

Question

Accepted Answer

Retesting is testing the same functionality again to ensure the defect is fixed, while regression testing is testing the unchanged parts of the application to ensure new changes do not impact existing functionality.

Retesting focuses on the specific defect that was found and fixed, while regression testing focuses on ensuring that new changes do not introduce new defects.
Retesting is usually performed by the same tester who found the defect, while regression testing can be performed by any tester.
Retesting is a subset of regression testing, as it only focuses on the specific defect, while regression testing covers the entire application.
Example: If a bug was found in the login functionality and fixed, retesting would involve testing the login functionality again to ensure the bug is fixed. Regression testing would involve testing other parts of the application to ensure the fix did not introduce new bugs.
