International Software Testing Qualifications Board (ISTQB) Foundation Level Practice Test

The main goal of confirmation testing, often referred to as re-testing, is to verify that a specific defect or issue that was previously reported has been successfully fixed. When a defect is identified, it undergoes a process where developers implement a fix. Confirmation testing is then carried out to ensure that the specific failure condition no longer exists and that the original issue has been resolved. This process serves to validate the effectiveness of the modification made.

In this context, while confirming that no new defects have been introduced is important in overall testing processes, it is not the primary focus of confirmation testing. Similarly, validating functionality across different platforms and ensuring system performance under various conditions pertains to broader testing objectives, rather than specifically assessing the resolution of a previously identified defect. Hence, the emphasis in confirmation testing is strictly on the rectification of the original issue.
