The Defect Life Cycle outlines the stages a defect goes through from identification to closure. Key stages include:
Identification:
- The defect is discovered and reported by testers or users.
Triage:
- The defect is evaluated for severity and impact on the system.
- Prioritisation occurs to determine which defects need immediate attention.
Analysis:
- Developers analyse the defect to understand its root cause.
- This may involve replicating the issue in a controlled environment.
Fixing:
- Developers implement changes to resolve the defect.
- Code modifications are made based on the analysis findings.
Retesting:
- The modified code is tested again to ensure that the defect has been resolved.
- This may involve re-executing previously failed test cases.
Verification:
- Final checks are done to confirm that the fix works as intended and does not introduce new issues.
Closure:
- Once verified, the defect is marked as closed in the tracking system.
- Documentation of how the defect was resolved is often included.
Understanding the Defect Life Cycle helps teams manage defects effectively and improve overall software quality.
