Add E2E Tests (Playwright)

Use this skill when the user asks to add end-to-end tests, browser tests, integration tests, or set up Playwright.

Steps

1. Install Playwright

   npm init playwright@latest
   

   This creates playwright.config.ts, a tests/ directory, and installs browsers. If the project already has a test runner, install manually:

   npm install -D @playwright/test
   npx playwright install
