Contract Testing & Service Virtualization

Effective practitioners need to know what to do, why it matters and how to recognise a weak result. Contract Testing & Service Virtualization develops that judgement by helping learners verify consumer-provider expectations early and simulate unavailable, costly or unreliable dependencies for focused integration testing. The programme integrates integration risk, consumer-driven contracts and contract-by-example and consumer tests rather than teaching them as isolated topics. Participants model interactions, create consumer contracts, verify provider states, design stubs for success and fault cases and place contract verification in a delivery pipeline. They learn where contracts prevent breaking changes, where mocks can mislead and how virtual services support deterministic testing without replacing essential integration evidence.

Learning Outcomes

  • Distinguish schema, contract, functional and integration testing.
  • Create consumer expectations from concrete request-response examples.
  • Verify provider behaviour against published contracts.
  • Design virtual services for unavailable and failure scenarios.
