# WireMock Standalone Docker Skill ## Overview Provides patterns for running WireMock as a standalone Docker container to mock external APIs during integration and end-to-end testing. Runs WireMock as a separate service that simulates real API behavior for testing HTTP clients, retry logic, and error handling. ## When to Use Use when you need to: - Mock external APIs during integration or end-to-end testing - Simulate error conditions (timeouts, 5xx, rate limiting) without real services - Test HTTP client configurations, retry logic, and error handling - Create portable, reproducible test environments - Validate API contracts before implementing the real service ## Instructions ### Step 1: Set Up Docker Compose Create a `docker-compose.yml` with WireMock 3.5.2, port mapping, and volume mounts for mappings and files: ```yaml version: "3.8" services: wiremock: image: wiremock/wiremock:3.5.2 ports: - "8080:8080" volumes: - ./wiremock:/home/wiremock command: ["--global-response-templating"] ``` ### Step 2: Create Directory Structure Create the WireMock configuration directories: ``` wiremock/ ├── mappings/ # JSON stub definitions └── __files/ # Response body files ``` ### Step 3: Define API Mappings Create JSON stub files in `wiremock/mappings/` for each scenario: - **Success**: Return 200 with JSON body - **Not Found**: Return 404 - **Server Error**: Return 500 - **Timeout**: Use `fixedDelayMilliseconds` - **Rate Limit**: Return 42...
