Unit test external REST API integrations with WireMock HTTP mocking and request verification. Patterns for testing external REST API integrations with WireMock: stubbing responses, verifying requests, error scenarios, and fast tests without network dependencies. If stub not matching : Check URL encoding, header names, use urlEqualTo for query params. If tests hanging : Configure connection timeouts in HTTP client; use withFixedDelay() for timeout simulation. If port conflicts : Always use wireMockConfig().dynamicPort() . See references/advanced-examples.md for error scenarios, body verification, timeout simulation, and stateful testing. - Stub HTTP responses with configurable status codes, headers, and JSON bodies; verify request details including headers, query parameters, and request bodies - Test error scenarios (4xx/5xx responses, timeouts, malformed responses) without calling real APIs or hitting rate limits - Use dynamic port allocation to avoid conflicts in parallel test execution; automatic cleanup between tests via JUnit 5 extension registration - Supports request matching by URL, HTTP method, headers, and JSON path expressions for precise stub targeting - Testing services calling external REST APIs - Stubbing HTTP responses for predictable test behavior - Testing error scenarios (timeouts, 5xx errors, malformed responses) - Verifying request details (headers, query...
