Software Quality Assurance Practice Exam

What should be done with error corrections in software?

1. They should be tested only if they are major errors.

2. All errors should be temporarily ignored.

3. Corrections must undergo significant testing in the original program.

4. Documentation should always come before fixing the errors.

The correct answer is: Corrections must undergo significant testing in the original program.

The focus on significant testing of corrections in the original program is essential because it ensures that the fixes do not introduce new issues while resolving existing ones. When any error is corrected, it often modifies the behavior of the software, which could potentially affect other areas of the application. By thoroughly testing the corrections within the context of the original program, it ensures that the fix is effective and does not compromise other functionalities or introduce regression errors. Testing after corrections also validates that the root cause of the error has been addressed adequately. Without this testing, one might mistakenly believe the software is functioning correctly when it may still have underlying problems. This is a key principle in software quality assurance as it maintains the integrity and reliability of the software product. In contrast, only testing major errors fails to recognize the significance of minor errors, which can also affect user experience or system performance. Ignoring errors entirely undermines the quality of the software and can lead to larger issues down the line. Similarly, prioritizing documentation before corrections can lead to delays in resolving critical errors and does not address the importance of ensuring that those corrections work effectively in practice.
