Tracking Defects

When tracking defects in a software development or testing environment, it is essential to understand the different states that a defect can go through during its lifecycle. The following are common defect states:

New – Rejected: When a new defect is reported, it undergoes an initial review process. If the defect is deemed invalid or a duplicate, it is rejected.
Open: Defects that are valid and accepted for resolution are marked as open.
Fixed – Reopened – Open: After a defect is fixed by the development team, it is retested. If the defect reoccurs, it is marked as reopened and goes back to an open state for further investigation.
Closed: Once a defect is verified to be fixed and passes all retesting, it is closed, indicating that the issue has been successfully resolved.

Understanding these defect states is crucial for effectively managing the defect resolution process and ensuring the quality of the software product.
