Service Virtualization – ISTQB Definition
Last Updated: July 12, 2026 · SoftwareTestPilot QA Team
Official ISTQB Definition
A method to emulate the behavior of specific components in heterogeneous, component-based applications such as API-driven applications, cloud-based applications and SOA.
In simple words
Fake entire services (payments, third-party APIs) so tests aren't blocked by them.
Exam tip
Service virtualization scales beyond unit-test mocks and covers whole systems (WireMock, Mountebank).
