Playwright E2E Best Practices for AI Agents
How our Playwright E2E skill teaches AI agents to write robust, maintainable end-to-end tests.
Writing E2E tests that are fast, reliable, and maintainable is hard. Teaching an AI agent to do it well is even harder. Here's how the Playwright E2E skill approaches this challenge.
Page Object Model
The skill teaches AI agents to always use the Page Object Model pattern. Instead of writing raw selectors in tests, it creates reusable page classes:
npx qaskills add playwright-e2eOnce installed, your AI agent structures every test with proper page objects, separating selectors from test logic.
Auto-Waiting Locators
One of the most common mistakes in E2E testing is using fragile selectors and manual waits. The skill teaches agents to use Playwright's built-in auto-waiting locators like `getByRole`, `getByText`, and `getByTestId` instead of raw CSS selectors.
Fixture-Based Setup
The skill guides agents to use Playwright's fixture system for test setup and teardown. This ensures tests are isolated and don't share state, which prevents flaky failures.
Cross-Browser Testing
The skill includes patterns for configuring tests to run across Chromium, Firefox, and WebKit, with proper browser-specific handling when needed.
