Playwright is an open-source framework developed by Microsoft for end-to-end testing and automation, renowned for its speed, reliability, and ease of setup, making it a favorite among test automation frameworks. It supports cross-browser, cross-platform, and cross-language testing, allowing testers to write modular tests in environments best suited to their needs. Playwright's architecture, which uses a single WebSocket connection for communication, enhances test execution speed and stability, contrasting with the HTTP requests used by Selenium. Key features include the Trace Viewer for reviewing test execution and the Test Generator for creating test scripts, while integrations with CI/CD tools and cloud platforms like LambdaTest extend its functionality for scalable testing. The framework also offers a user-friendly experience with tools like VS Code extensions, enabling easier test execution, debugging, and real-time code editing. As Playwright continues to gain popularity, it stands out with unique features and regular updates, challenging established tools like Selenium in the browser testing space.
