When a defect is detected and fixed, what is the process called to confirm that the original defect has been successfully removed?

When a defect is detected and subsequently fixed, the process to verify that the original defect has been successfully removed is known as confirmation testing. This type of testing involves checking the specific area of the software where the defect was identified to ensure that the fix works as intended and that the defect has been effectively addressed.

Confirmation testing focuses on validating that the issue has been resolved without introducing new defects. It is often conducted immediately following the implementation of a defect fix, ensuring that the original problem does not persist in the software.

While regression testing examines the application as a whole, ensuring that recent changes have not negatively affected existing functionality, confirmation testing is specifically targeted at confirming that a particular defect has been eliminated. Maintenance testing, on the other hand, refers to ongoing testing activities after software has been released, which may include fixing defects, but does not specifically address the proof of removal of a single defect as confirmation testing does.
