Service virtualisation in test environments is used to
AEncrypt data flowing between two services
BDiscover new services in a service registry
CSimulate dependencies that are unavailable
DReplace all production services permanently
Answer & Solution
Correct answer: C. Simulate dependencies that are unavailable
Service virtualisation (WireMock, Mountebank, Hoverfly, Mockoon) lets a test target a 'virtual' dependency with scripted responses, useful when the real dependency is unavailable, costly, slow, or not yet built.
