Confirmation Testing, also known as re-testing, is the process of verifying that previously identified defects have been successfully fixed by executing the same test cases that initially detected the issues. Key aspects include:
Purpose:
- Ensure the defect is resolved
- Verify fix doesn’t introduce new issues
Process:
- Re-run failed test case
- Check related functionality
- Verify in different environments
Timing:
- Performed after defect fix
- Before releasing the fix
Benefits:
- Confirms issue resolution
- Maintains software quality
- Prevents regression
Challenges:
- Ensuring comprehensive retesting
- Balancing thoroughness with time constraints
Confirmation testing ensures effective defect resolution.
