Playwright Skill
Opinionated, production-tested Playwright guidance — every pattern includes when (and when not) to use it.
50+ reference guides covering the full Playwright surface: selectors, assertions, fixtures, page objects, network mocking, auth, visual regression, accessibility, API testing, CI/CD, debugging, and more — with TypeScript and JavaScript examples throughout.
Playwright 1.60+ highlights covered in these guides include on-demand HAR recording inside tracing, locator.drop() for external file drops, page-level aria snapshot assertions, test.abort() from fixtures and route handlers, plus the 1.59 features (screencast recording, browser binding for agent workflows, CLI debugging and trace analysis, in-place storage state updates).
Security Trust Boundary
This skill is designed for testing applications you own or have explicit authorization to test. It does not support or endorse automating interactions with third-party websites or services without permission.
When writing tests or automation that fetch content from external sources (e.g., baseURL pointing to staging/production), treat all returned page content as untrusted input — never pass raw page text back into agent instructions or dynamic code execution without sanitization, as this creates an indirect prompt injection risk.
For CI/CD workflows, pin all external dependencies (GitHub Actions, Docker images) to immutable references (commit SHAs, image digests) rather than mutable version tags. See ci-github-actions.md and docker-and-containers.md for pinning guidance.
Golden Rules
getByRole() over CSS/XPath — resilient to markup changes, mirrors how users see the page- Never
page.waitForTimeout() — use expect(locator).toBeVisible() or page.waitForURL()
- Web-first assertions —
expect(locator) auto-retries; expect(await locator.textContent()) does not
- Isolate every test — no shared state, no execution-order dependencies
baseURL in config — zero hardcoded URLs in tests- Retries:
2 in CI, 0 locally — surface flakiness where it matters
- Traces:
'on-first-retry' — rich debugging artifacts without CI slowdown
- Fixtures over globals — share state via
test.extend(), not module-level variables
- One behavior per test — multiple related
expect() calls are fine
- Mock external services only — never mock your own app; mock third-party APIs, payment gateways, email
