Test Condition – ISTQB Definition
Last Updated: July 12, 2026 · SoftwareTestPilot QA Team
Official ISTQB Definition
An aspect of the test basis that is relevant in order to achieve specific test objectives.
In simple words
A ‘what to test’ statement — one idea, one risk, or one requirement — that later becomes one or more test cases.
Exam tip
Test conditions are the bridge between the test basis (‘why’) and test cases (‘how’).
