Which of the following best describes confirmation testing?

Confirmation testing is specifically focused on validating that a defect has been successfully fixed. After a defect is identified and addressed by the development team, confirmation testing is performed to ensure that the reported issue is no longer present and that the fix functions as intended. This type of testing is crucial to confirm that the corrective actions taken have resolved the specific issues that were initially reported.

This process doesn't evaluate compliance with broader specifications, which would involve a different type of testing focused more on the overall feature set rather than a specific defect. It also differs from tests that validate new features, which would be aimed at checking functionalities that have been newly introduced, rather than correcting previously identified bugs. Lastly, confirmation testing takes place at various phases of the testing process and is not confined to the end of development; it specifically targets tested fixes rather than the overall completion of the development stage.
