API mocking intercepts network requests to return deterministic responses, eliminating flaky tests. It supports both browser and Node environments by simulating real-world REST and GraphQL interactions without hitting actual endpoints.
Yes, you can use Mock Service Worker to simulate both GraphQL and REST API calls. It provides centralized, declarative mocks with fine-grained control over responses, allowing you to model success, errors, and edge cases seamlessly.
Yes, MSW API mocking integrates seamlessly with common test runners like Jest and Vitest. This integration allows you to model success, errors, delays, and edge cases directly within your UI and backend test suites.
To set up MSW v2 for HTTP mocking, define declarative request handlers to intercept network calls. The process enforces strict URL matching and explicit body parsing, utilizing lifecycle events for debugging.
The best way to debug intercepted network requests is by utilizing MSW lifecycle events. These events provide visibility into request matching and response resolution, ensuring your mocked HTTP and GraphQL calls behave as expected.
