-To run tests in interactive mode, run `npm run cypress:debug` from the root directory of the project. It will open Cypress Test Runner and allow to run tests in interactive mode. [More info about "How to run tests"](../../cypress-e2e/README.md#how-to-run-tests)

-To build app and run test in headless mode, run `yarn e2e:ci`. It will build app and run tests for this workspace in headless mode. If tets failed cypress will create `cypress` directory in sample root folder with screenshots and videos.
+- `pnpm test:e2e`: launches the host and remote servers and runs the Playwright suite headlessly.
+- `pnpm test:e2e:ui`: opens the Playwright test runner UI for local development.
+- `pnpm test:e2e:debug`: starts the suite in headed mode with Playwright's inspector attached.
+- `pnpm e2e:ci`: installs the required browsers (when needed) and executes the suite with a list reporter while collecting failure artifacts (traces, screenshots, videos).
