Playwright is a powerful tool for end-to-end testing of web applications. It enables reliable testing across multiple browsers (Chromium, Firefox, WebKit), platforms (Windows, Linux, macOS), and languages (TypeScript, JavaScript, Python, .NET, Java).
Key Features:
- Cross-Browser Testing: Ensures your application works seamlessly across different browsers.
- Auto-wait: Eliminates flaky tests by waiting for elements to be actionable before performing actions.
- Web-first Assertions: Provides assertions specifically designed for dynamic web applications.
- Tracing: Captures detailed execution traces, videos, and screenshots for debugging.
- Browser Contexts: Creates isolated browser contexts for each test, ensuring full test isolation with minimal overhead.
- Codegen: Generates tests by recording user actions.
- Playwright Inspector: Inspects pages, generates selectors, and steps through test execution.
- Trace Viewer: Investigates test failures with screencasts, DOM snapshots, and action explorers.
Use Cases:
- Automated end-to-end testing of web applications.
- Cross-browser compatibility testing.
- Regression testing.
- Performance testing.
- Mobile web testing with native mobile emulation.
