+##### End-to-End tests

+To run the end-to-end tests for Studio-Web, please check the following:
+
+- Ensure that you have built the `web-component` (run `npx nx build web-component`)
+- Check that `studio-cli` is installed and running (run `npx nx serve-web-api studio-web`)
+- Confirm that `studio-web` is up and running (run `npx nx run-many --targets=serve,serve-fr,serve-es --projects=studio-web --parallel 3`). Your browser must be able to load `http://localhost:4200/` before you proceed.
+- Verify that `playwright` is installed and configured (run `npx playwright install --with-deps firefox chromium webkit`)

+    npx playwright install --with-deps firefox chromium webkit &&  npx nx run-many --targets=serve-test-data,serve-web-api,serve,serve-fr,serve-es --projects=web-component,studio-web --parallel 6

+Once you have confirmed that everything is online and working run:
+`npx nx e2e studio-web` and wait for the report.
+
+**PS**: If you want to run a spec interactively you can run `npx nx e2e-ui studio-web` to get playwright interactive user interface.
