E2E Testing Patterns

Comprehensive Playwright patterns for building stable, fast, and maintainable E2E test suites.

When to Activate

• Writing or running Playwright E2E tests
• Setting up E2E test infrastructure for a new project
• Diagnosing or fixing flaky tests
• Configuring CI/CD pipelines for E2E testing
• Implementing the Page Object Model pattern
• Managing test artifacts (screenshots, videos, traces)
• Adding cross-browser coverage (Chromium, Firefox, WebKit) to an existing test suite
• Implementing test isolation strategies to prevent shared state between test runs
• Setting up visual diff checks or accessibility assertions as part of automated test flows
