+# E2E tests (Playwright)
+
+End-to-end tests for the Interledger.org Drupal site using Playwright.
+
+## Prerequisites
+
+- Node.js 18+ (20+ recommended)
+- Browsers for Playwright (`npm run install:browsers`)
+- The target site running locally or accessible via URL
+having the website running means:
+- files/ folder from production website in /web/sites/default/files
+- mysql production database correctly imported locally
+
+## Quick start (local)
+
+1) Start the local Drupal stack (optional — the test runner will also start it automatically if targeting localhost):
+
+```bash
+make -C local up
+# or:
+cd e2e && npm run local:up
+```
+
+This exposes the site at <http://localhost:8080> by default.
+
+2) In this `e2e/` folder, install deps and browsers:
+
+```bash
+npm install
+npm run install:browsers
+```
+
+3) Run the tests:
+
+```bash
+npm test
+# or explicitly against localhost (equivalent):
+npm run test:local
+```
+
+Tests default to `BASE_URL=http://localhost:8080`. To target a different environment:
+
+```bash
+BASE_URL=https://your-env.example.org npm test
+```
+
+Note: When `BASE_URL` is the default `http://localhost:8080` (and not in CI), the test runner will run `make -C ../local up` automatically and wait for the port to be ready before starting tests. If the stack is already running, it will reuse it.
+
+## Useful commands
+
+- Run headed: `npm run test:headed`
+- Debug mode: `npm run test:debug`
+- Show last report: `npm run show-report`
+- Codegen against current BASE_URL: `npm run codegen`
+
+## Running individual tests
+
+To run a specific test file:
+
+```bash
+npx playwright test tests/seo.spec.ts
+npx playwright test tests/performance.spec.ts
+npx playwright test tests/accessibility.spec.ts
+# etc.
+```
+
+To run a specific test within a file (by test name):
+
+```bash
+npx playwright test tests/seo.spec.ts -g "homepage has title"
+```
+
+To run tests matching a pattern:
+
+```bash
+npx playwright test --grep "homepage"
+```
+
+To run tests in a specific browser:
+
+```bash
+npx playwright test tests/seo.spec.ts --project=chromium
+npx playwright test tests/seo.spec.ts --project=firefox
+npx playwright test tests/seo.spec.ts --project=webkit
+```
+
+You can combine options with the npm scripts:
+
+```bash
+BASE_URL=http://localhost:8080 npx playwright test tests/seo.spec.ts --headed
+```
+
+Available test files:
+
+- `tests/seo.spec.ts` - SEO and meta tags
+- `tests/performance.spec.ts` - Performance budgets
+- `tests/accessibility.spec.ts` - Accessibility checks
+- `tests/navigation.spec.ts` - Navigation tests
+- `tests/images.spec.ts` - Image optimization
+- `tests/error-pages.spec.ts` - Error page handling
+- `tests/console-errors.spec.ts` - Console error checks
+- `tests/smoke.spec.ts` - Basic smoke tests
+
+# Managing the local Docker stack from here
+
+- Start: `npm run local:up`
+- Stop: `npm run local:down`
+
+## CI
+
+There is a GitHub Actions workflow (`.github/workflows/e2e.yml`) that runs tests when manually dispatched and requires a `base_url` input. It does not start Drupal; point it to a running environment (e.g., staging).
