-To run e2e cypress tests, execute `npm run cypress`.
+### 📷 Running Playwright tests
+The end-to-end tests use [Playwright](https://playwright.dev/) and a disposable Nextcloud Docker container.
 
-The `visual-regression` tests require additional care as they depend on installation of fonts in the application. To achieve repeatable results run the tests using `npm run cypress:visual-regression`. This will build the app with the required fonts and run the tests.

+npm run test:e2e
