Real-Time Testing – ISTQB Definition
Last Updated: July 12, 2026 · SoftwareTestPilot QA Team
Official ISTQB Definition
Verification that a system meets strict timing deadlines under load, common in embedded, avionics, and control systems.
In simple words
Making sure a system responds within a guaranteed time — every time, no exceptions.
Exam tip
Real-time systems fail when a deadline is missed, not just when output is wrong. Timing is part of correctness.
