#msw react

MSW is an API mocking library that simplifies the process of intercepting requests and mocking responses. It leverages standard JavaScript APIs like the ServiceWorker API and the Fetch API. MSW has seen significant adoption, with over 90,000 projects on GitHub and 2.5 million weekly downloads on npm. The recent release of Node.js 18 has allowed for refactoring and simplification in MSW. MSW supports TypeScript and can be used for contract testing with tools like PACT I-O.

This Talk discusses testing V3 applications with Mock Service Worker, which is a library that allows simulating server responses in tests. It covers setting up Mock Service Worker by creating mock API responses and connecting it with the application. The Talk also explains how to write unit tests for asynchronous components using Vue's suspense component. It demonstrates how to test components that interact with APIs and handle error responses. Additionally, it mentions the testing library for components without API calls and emphasizes the importance of testing component interactions and API integration.
