--- name: e2e-panther-playwright description: Write end-to-end tests with Symfony Panther 2.4 for browser automation or Playwright for complex scenarios capabilities: [read, search] tags: [testing] # projected by `bun run build` — do not edit by hand allowed-tools: - Read - Glob - Grep --- # E2e Panther Playwright (Symfony) ## Use when - A flow needs a real browser: JavaScript, multi-page journeys such as login, checkout or signup. - `WebTestCase` cannot see the behavior because it depends on client-side rendering. - Cross-browser needs (WebKit, tracing, video) that WebDriver does not cover: run Playwright separately. - Debugging a browser test that fails only in CI. ## Default workflow 1. Pick the client: `static::createPantherClient()` for a real browser, `static::createClient()` when no JavaScript is needed. 2. Install `symfony/panther` and `dbrekelmans/bdi`, run `vendor/bin/bdi detect drivers`, and register `ServerExtension` in `phpunit.dist.xml`. 3. Extend `PantherTestCase` and drive the flow with explicit waits: `waitFor()`, `waitForVisibility()`, `waitForElementToContain()`. 4. Assert future state with `assertSelectorWillExist()` or `assertSelectorWillContain()`, current state with `assertSelectorIsVisible()`. 5. Keep the suite in `tests/E2E` and reset the database between tests (DAMADoctrineTestBundle or Foundry). 6. Debug with `PANTHER_NO_HEADLESS=1` and `--debug`; set `PANTHER_NO_SANDBOX=1` in CI. ## Guardrails - Never rely on implicit timing: every async step gets a `waitFor*` or an `assertSelectorWill*`. - Target `data-testid` attributes, not styling classes. - Delete the PNGs written by `takeScreenshot()` or `PANTHER_ERROR_SCREENSHOT_DIR`; never commit them. - E2E is slow: cover critical paths only and keep it apart from unit tests. ## Progressive disclosure - Use this file for execution posture and risk controls. - Open references when deep implementation details are needed. ## Output contract - E2E test files, with the client type and the wait strategy used. - Driver setup, `ServerExtension` registration and the `PANTHER_*` variables needed locally and in CI. - Confirmation that screenshots were cleaned up. ## References - `reference.md`
