What is the focus of confirmation testing?

Confirmation testing primarily focuses on rerunning test cases that previously indicated a failure to verify if the issues have been resolved. This practice is crucial in the testing lifecycle as it ensures that the fixes implemented by the development team have successfully addressed the defects, confirming the application's correct functionality. The goal is not just to identify faults but to ensure that previous problems do not persist after code changes or bug fixes have been made.

This testing type is often associated with regression testing, but it specifically aims at the particular areas where defects were recorded. By confirming that a fix works under the original failure conditions, it builds confidence in the quality and reliability of the software application.
