Browser, E2E, and API testing with Playwright

This skill provides patterns and conventions for Playwright browser, E2E, and direct API tests, including SPA-specific techniques for routing, API mocking, and async navigation.

When to use this skill

• Writing browser or E2E tests for user flows
• Testing page routing and redirects
• Testing dialog/modal interactions
• Testing endpoints directly through Playwright's APIRequestContext
• Creating mocks, fixtures, and assertions for Playwright tests
• Debugging failing Playwright browser, E2E, or API tests
• Choose the testing skill from the task and the project's established test tool. Route generic requests for mocks or test data according to that context.

Project configuration

When setting up or modifying playwright.config.ts, see references/configuration.md for conventions on web server setup, reporters, traces, screenshots, and CI behavior.
