Vite Loading Demo [yFiles for HTML]

Vitest Demo

This demo shows how to use Vitest for testing a yFiles for HTML web application. For interaction with the web browser it uses Playwright.

To run the test:

Go to the demo's directory demos-ts/testing/vitest.
Run npm install.
Run the test with npm run test.
Run the test UI with npm run test-ui.

The test is run in Chromium in headless mode.

You can also just start the app and interact with it by running npm run dev.

A simple way to make a yFiles App testable is making the GraphComponent available to the testing framework. In this app, this is achieved by setting the instantiated GraphComponent as a property of the Window object.
