Test Metric – ISTQB Definition
Last Updated: July 12, 2026 · SoftwareTestPilot QA Team
Official ISTQB Definition
A measure used to quantify a test-related attribute (e.g. pass rate, defect density, coverage).
In simple words
A number you track to know how testing is going — coverage %, defects found, tests passed.
Exam tip
Combine progress, product-quality and process metrics — no single metric tells the full story.
Related terms
- Defect DensityHow many defects per 1,000 lines of code, page of spec, or story point.
- Test CoverageHow much of a chosen coverage target (statements, branches, requirements, risks) your tests actually hit.
- Test Progress ReportA recurring status report during testing — usually weekly or per sprint — showing burn-down and risks.
