Retesting in software testing is the process of re-executing previously failed test cases after a defect has been fixed. Its main purpose is to confirm that the specific issue has been resolved and no longer exists in the application. Unlike other testing types, retesting is focused only on defect verification and is performed on the exact scenarios where the bug originally occurred.
This step is critical because fixing a bug does not automatically guarantee that the issue is resolved correctly. Retesting ensures that the fix works under the same conditions and that the expected behavior is achieved. Without proper retesting, teams risk releasing software with unresolved or partially fixed defects, which can impact reliability and user experience.
Retesting is often confused with regression testing, but they serve different purposes. Retesting focuses on verifying a specific defect fix, while regression testing ensures that recent changes have not broken existing functionality across the system. In practice, retesting is usually performed first to validate the fix, followed by regression testing to check overall system stability.
Modern development requires faster and more efficient retesting processes. Tools like Keploy help simplify this by capturing real API interactions and automatically generating test cases that can be replayed after fixes. This reduces manual effort, speeds up validation, and ensures that bug fixes are verified quickly in real-world scenarios.
