Multiple Condition Testing – ISTQB Definition
Last Updated: July 12, 2026 · SoftwareTestPilot QA Team
Official ISTQB Definition
A white-box test design technique in which test cases are designed to execute combinations of single condition outcomes within one statement.
In simple words
Cover every combination of true/false values of the sub-conditions inside a compound decision.
Exam tip
For N conditions you get up to 2^N combinations — expensive; MC/DC is a cheaper alternative.
