A guide to Vitest automated testing with Vue components

Vitest is a fast and efficient testing framework developed by the Vue and Vite teams, designed to facilitate automated testing for Vue components. It offers seamless integration with Vue applications due to its shared configuration file with Vite and is compatible with most Jest APIs, making it an appealing alternative for projects transitioning from Jest. The framework supports hot module reloading (HMR), which reflects changes in the server when test files are modified, and it accommodates snapshot testing to track UI changes. Furthermore, Vitest allows for mocking HTTP requests using tools like Mock Service Worker (MSW) and provides native code coverage support via c8 and Istanbul. Migrating from Jest to Vitest is straightforward due to their similar APIs, enabling developers to maintain testing efficiency and reliability in Vue projects.
