Which action best represents proper retesting after defects are fixed?

• A. Ignoring defects
• B. Retesting after defects are fixed
• C. Skipping test cases
• D. Performing only manual tests

Answer: (B)

Retesting after a defect is fixed is the essential step to confirm the fix actually resolves the issue and that nothing nearby was broken. When a defect is corrected, you re-run the original failing test to verify that the behavior now matches expectations. You also typically broaden to related tests to ensure the fix didn’t introduce new problems elsewhere. This validates the fix before moving forward and helps prevent slipping defects into production. Other approaches skip or ignore the defect, skip test cases, or rely solely on one testing style; none of these provide the necessary confirmation that the issue is truly addressed and safe, and they leave risk unassessed.
