Doublers in Tests. Wiremock vs Mockito
summary
Compares Mockito and WireMock with concrete code examples and setup: WireMock runs as a standalone jar with embedded Jetty controlled by JUnit rules, replaces HTTP services in unit and integration tests, and verifies requests (spies) and responses; default behavior returns default 404 unless configured to fail fast; supports transformation for JWT and advanced features like proxy and failure injection. Demonstrates generating Pact files from WireMock and validating contracts against Swagger, and warns that doubles go stale so pipelines must verify doubles against real provider APIs.
