Playwright best practices for E2E, component, API, visual, and accessibility testing: flaky-test fixes, Page Object Model, CI/CD, mocking, auth/OAuth, axe-core, uploads, WebSockets, mobile, GraphQL, PWA, Electron, and extensions. Use when writing or debugging Playwright tests. NOT for: non-Playwright frameworks (Cypress/Selenium-only) or general CI without Playwright.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

How to install

The exact contents, by fingerprint
mdr add ninjasln-labs/agent-skills/playwright-best-practices@sha256:5337b1d600b95e2e

The line at the top of this page pins the label v1.1.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
