What problem does it solve?

Java services often struggle to reliably test integration points with external HTTP systems. This skill provides a guided approach to set up, review, or improve Java integration tests using WireMock stubs, and generates a reusable BaseIntegrationTest scaffold.

Core Features & Use Cases

• Detects outbound HTTP dependencies in code (HttpClient, RestTemplate, Feign, Retrofit, OkHttp) and proposes a REST-testing topology based on WireMock.
• Generates a tailored BaseIntegrationTest.java with WireMockExtension, @RegisterExtension, and a @BeforeAll block that propagates coordinates via System.setProperty().
• Creates starter WireMock mappings under src/test/resources/wiremock/mappings per identified service.
• Encourages per-test stub registration and verification of HTTP interactions to keep tests isolated and deterministic.
• Documents anti-patterns to avoid (e.g., global stubs, mocked HTTP clients) to preserve real HTTP-pipeline testing.

Quick Start

Use a clean Maven build to validate compilation and trigger the scaffolding workflow.
