Overview
Jest is a JavaScript testing framework with snapshots, mocking and code-coverage reporting. Tests run in separate processes, and the getting-started guide demonstrates adding a test file and running the package test script. Check bundler compatibility: the current guide explicitly states that Jest is not supported by Vite.12
What you can do
Get started
- Install Jest with the project’s package manager, create an example test file and run the configured test script.2
