Last Updated: July 12, 2026 · SoftwareTestPilot QA Team
Official ISTQB Definition
The percentage of condition outcomes that have been exercised by a test suite.
In simple words
Percent of individual boolean sub-conditions that have been evaluated true and false.
Exam tip
In an if (A && B), condition coverage cares about A and B separately, not the overall decision.
