Which of the following best describes retesting?

Retesting specifically refers to the process of executing the same test cases after a defect has been fixed to confirm that the identified issue has been successfully resolved. The primary goal of retesting is to verify the effectiveness of the bug fix, ensuring that the initial problems no longer occur in the software after modifications have been made.

This process is critical because verifying bug fixes helps maintain software quality and ensures that changes made to resolve issues do not introduce new defects or affect existing functionality. Retesting typically involves using the same test conditions, data, and expected results as were used in the initial testing that uncovered the defect.

In contrast, running tests to ensure no new errors are introduced aligns more closely with regression testing, which is distinct from the focused nature of retesting. Re-running the same test to reproduce the problem usually describes how a bug was initially found rather than addressing the verification phase post-fix. Conducting wide tests without focusing on any criteria does not align with the specific aims of either retesting or regression testing but rather suggests a lack of targeted assessment.
