Test Coverage – ISTQB Definition
Last Updated: July 12, 2026 · SoftwareTestPilot QA Team
Official ISTQB Definition
The degree to which specified coverage items have been determined or have been exercised by a test suite, expressed as a percentage.
In simple words
How much of a chosen coverage target (statements, branches, requirements, risks) your tests actually hit.
Exam tip
Coverage is meaningful only relative to the item you're measuring — always name the item.

- Code CoverageThe percentage of code your tests actually run — measured at statement, branch or condition level.
- Requirements CoverageHow many requirements have at least one test linked to them.
- Branch CoverageExecuted branches ÷ total branches × 100 — covers both true and false outcomes of each decision.
