What action should be taken if a test still passes after a method update?

• A. Rely on the existing results as they are sufficient.
• B. Ignore the results and proceed with the next task.
• C. Verify for false positives and consider new tests.
• D. Remove the tests since they are outdated.

Answer: (C)

When a test passes after a method update, it's crucial to consider the possibility of false positives. This situation suggests that the updated method might still be producing expected results, but it does not guarantee that the logic is correct or that it adequately covers the new functionality. By verifying for false positives, you ensure that the tests are still relevant and effectively validate the changes made in the method. Furthermore, considering new tests or refining existing ones to cover different scenarios or edge cases can help ensure the updated method is robust. It's essential to validate that the changes made haven't inadvertently compromised the functionality or introduced new bugs, so adopting a thorough testing approach ensures software reliability. This mindset fosters confidence in the codebase as it evolves. The other choices present options that overlook necessary diligence in testing. Relying on existing results without scrutiny might lead to undetected issues, while ignoring results could allow defects to slip through. Removing tests entirely would negate any validation of functionality that might still be relevant.
