This Skill prevents broken or flaky API mocking setups by teaching the correct MSW v2 patterns for handler matching, request/response handling, and test isolation so your tests fail loudly instead of silently.
Tell an AI to generate an MSW v2 server setup and a set of REST and GraphQL request handlers that correctly parse request bodies, match URLs, and enforce strict unhandled-request failures for your test suite.
High-intent search queries and answers about installing and using this skill.
Prevent flaky mocks in MSW v2 by structuring request handlers correctly, resetting handlers between tests, and isolating concurrent tests with server.boundary() to eliminate handler leakage and race conditions.
MSW GraphQL mocking requires correct resolver destructuring and explicit validation of GraphQL error and operation-name matching behavior to ensure your handlers intercept the intended queries accurately.
Parse request bodies explicitly in your MSW handlers and use the correct HttpResponse syntax to construct responses, ensuring your HTTP mocks behave consistently across different testing environments.
The best way to handle unhandled requests in MSW test isolation is to enforce strict unhandled-request failures and configure server lifecycle hooks so tests fail loudly instead of silently.
Yes, you can mock streaming responses and simulate real-world REST API behavior using MSW v2 by applying correct handler architecture and response construction patterns for accurate API simulation.
Yes, configuring correct msw/node entrypoints is required for proper server lifecycle management and deterministic test behavior across unit and integration testing workflows.
