What is a retest?

Retest is the process of testing a specific defect or functionality again after the developer has fixed the identified issue. The goal of retesting is to ensure that the bug is truly resolved and that the fix works correctly.

The retesting process includes:

• Re-executing test cases that identified the defect.
• Checking that the fix did not cause new problems.

For example, if there was an error when uploading a file in the application, a retest of the upload is performed after the fix to confirm that the issue has been resolved.
