Which term refers to a fault that has been fixed but not yet validated?

The term that refers to a fault that has been fixed but not yet validated is a defect. In software testing terminology, a defect specifically denotes a condition in the software that deviates from the expected behavior or requirements. When a defect is identified and subsequently fixed by the development team, it remains a defect until it has been verified through testing to ensure that the fix works as intended and does not introduce new issues.

This validation process is crucial because it confirms that the resolution is effective and that the software behaves correctly after changes have been made. In essence, a defect represents an outstanding issue that is pending confirmation of resolution, making it a key part of the defect lifecycle in quality assurance practices.
