The directory structure and commands for tests are the same as the projects created by @vue/cli.

This repository uses Cypress as an example to illustrate how to setup end-to-end tests with Vite.

To try it out, run:

yarn test:e2e

Running end-to-end tests with Vite is no different from other bundlers:

• Bundle the app for production;
• Start a static HTTP server;
• Run the command from the test framework.

Vite provides a built-in static HTTP server to preview the build results. We can start it by running vite preview (or yarn serve). The default URL of this preview server is http://localhost:5000/. So we also set the baseUrl option in cypress.json to this URL.

vite preview serves the dist folder's content, which results from the vite build command. So we add a preserve hook to the script section of package.json to run this command. Therefore, whenever you run npm run serve, vite build will be executed first.

yarn test:unit

This repository uses @web/test-runner and vite-web-test-runner-plugin to execute unit tests.

The test framework is Mocha and the assertion library is Chai.
