In this week's lesson, we explore Defect Management—a critical process in software testing. A bug, defect, or issue can derail a project if not managed properly. Defect management ensures that issues are identified, logged, prioritized, and resolved in a systematic manner.
Key components of a well-written bug report include:
- Title: A concise summary
- Description: Detailed explanation of the bug
- Steps to Reproduce: Clear instructions to replicate the issue
- Expected vs. Actual Results: Highlighting the discrepancy
- Environment Details: Information about the software, hardware, and configuration
Severity Levels:
Bugs are categorized by their impact on functionality, ranging from P1 (Critical) to P5 (Trivial). These labels help prioritize issues based on urgency.
- P1 (Critical): Severe bugs that need immediate attention.
- P2 (High): Major bugs that significantly impact functionality.
- P3 (Medium): Moderate bugs that affect some functionality but have workarounds.
- P4 (Low): Minor bugs that have little impact on functionality.
- P5 (Trivial): Very minor issues that are mostly cosmetic.
Defect Management Process:
- Defect Discovery: Identifying and reproducing the issue.
- Defect Logging: Recording the defect in a tracking tool.
- Defect Triage: Prioritizing based on severity.
- Defect Fixing: Developers address the issue.
- Defect Verification: Testers verify the fix.
- Defect Closure: The issue is marked as resolved.
Defect Clustering:
A key insight in testing is that most defects tend to cluster in a small number of modules, allowing testers to focus their efforts where it's most needed.
By mastering defect management, you'll significantly improve the quality and reliability of your software, making it more robust and stable.
