Hi! My name is [Artem](https://kettanaito.com), and in this course I will teach you how to mock WebSocket APIs with [Mock Service Worker](https://mswjs.io). You and I are going to build a chat application mock-first, and you will learn how to intercept WebSocket connections, handle client and server events, and also test the code that relies on WebSocket in Vitest and Playwright. Let's go!
