End-to-End Testing with Playwright

Purpose

Write browser tests that fail only when the application is broken. An end-to-end suite that fails randomly is worse than no suite: it consumes attention and trains the team to ignore red.

When to Use

• Testing a complete user journey through a real browser.
• Replacing a flaky Selenium or Cypress suite.
• Testing flows that cross pages, tabs, or authentication.
• Debugging an intermittent E2E failure.
