Microservices Testing – ISTQB Definition
Last Updated: July 12, 2026 · SoftwareTestPilot QA Team
Official ISTQB Definition
Testing strategies specific to systems built as independently deployable services communicating over the network.
In simple words
Testing a system where dozens of small services talk over HTTP or messaging.
Exam tip
Rely on contract tests + service virtualization; end-to-end tests do not scale.
Related terms
- Contract TestingProducer and consumer each publish and verify a shared contract so integrations don't silently break.
- Service VirtualizationFake entire services (payments, third-party APIs) so tests aren't blocked by them.
- API TestingTesting at the service boundary — sending requests to endpoints and asserting responses — without a UI.
