Testing produces a lot of raw data. Reporting and metrics turn that data into clear, honest information that helps stakeholders decide whether to release — and where to focus next.
Useful test metrics
- Test case pass rate — proportion of tests passing.
- Defect density — defects per area or per size of code.
- Defect severity breakdown — how serious the open issues are.
- Test coverage — how much of the requirements or code is exercised.
- Defect trend — are new defects rising or falling over time?
| Metric | Tells you | Watch out for |
|---|---|---|
| Pass rate | Current stability | Can hide weak coverage |
| Defect density | Risky areas | Depends on test depth |
| Coverage | What is tested | High % ≠ good tests |
Honesty over vanity: metrics should inform decisions, not flatter the team. A green dashboard built on shallow tests is worse than an honest amber one.
Conclusion
Reporting and metrics give testing a voice in decision-making. Chosen well and reported honestly, they turn test results into the clear risk picture that stakeholders need to release with confidence.
