Day 2: Deep Dive into Playwright Test Runner and Configuration playwright
- Modern E2E testing with Playwright involves managing, configuring, and scaling tests efficiently.
- The Playwright Test Runner is a robust framework supporting TypeScript/JavaScript, parallel execution, snapshots, fixtures and hooks, and more.
- It eliminates the need for external frameworks like Jest or Mocha and integrates seamlessly with Playwright APIs.
- The playwright.config.ts file serves as the central control hub for test behavior and configuration.
- Fields in playwright.config.ts include testDir, timeout, retries, use (for context options), reporter, and projects (for cross-browser testing).
- Playwright allows organizing tests using file and directory patterns and supports annotations for tagging and filtering tests.
- Fixtures in Playwright aid in defining reusable test setup and teardown logic for scenarios like login flows or user roles.
- Running and debugging tests in Playwright can be done using commands like npx playwright test and npx playwright test --debug.
- Advanced options like targeting specific browsers using --project or running tests based on tags are available in Playwright.
- Reports and trace viewer in Playwright provide detailed insights after test runs, including generating reports and view traces for debugging.
- The Playwright Test Runner offers TypeScript/JavaScript support, parallelism, browser compatibility, customizable configuration, fixtures, and tagging.
- Mastering the Playwright Test Runner and its configuration lays a strong foundation for scalable and maintainable test suites.
