+# E2E / Responsive tests
+
+These tests use Playwright and require a test Spotify account to be available via env variables.
+
+Required env variables:
+- TEST_SPOTIFY_ACCESS_TOKEN — a valid Spotify access token for a test account
+- TEST_SPOTIFY_ME_JSON — the JSON-stringified Spotify `me` object (example: `{"id":"user123","display_name":"Test"}`)
+
+Install and run locally:
+
+1) Install Playwright test runner:
+   npm i -D @playwright/test
+
+2) Install the browsers (recommended):
+   npx playwright install --with-deps
+
+3) Run tests:
+   TEST_SPOTIFY_ACCESS_TOKEN="<token>" TEST_SPOTIFY_ME_JSON='{"id":"...","display_name":"..."}' npm run test:e2e
+
+Notes:
+- Tests set the Pinia persisted auth store (`beardify-auth`) via localStorage before the app is loaded.
+- Prefer using a short-lived test access token and do not commit secrets to the repo.
+
+CI / GitHub Actions
+- A workflow has been added at `.github/workflows/playwright-e2e.yml` to run Playwright on pull requests and pushes to `master`.
+- The workflow expects two repository **secrets** to be configured in Settings → Secrets:
+  - `TEST_SPOTIFY_ACCESS_TOKEN` — a Spotify access token for a test account
+  - `TEST_SPOTIFY_ME_JSON` — JSON string of the Spotify `me` object (e.g. `{"id":"...","display_name":"..."}`)
+- If the secrets are not present, authenticated route tests will be skipped; public responsiveness and snapshot tests will still run.
