Playwright is an open-source framework for cross-browser automation and end-to-end web application testing, designed to be fast, reliable, robust, and evergreen. With its modern rendering engines and API supporting multiple programming languages, Playwright has gained significant popularity since its release in January 2020, with over 1.2 million NPM downloads per week. The framework addresses challenges such as flaky and slow tests by communicating with rendering engines via the WebSocket protocol, reducing points of test failure during test execution. Playwright Test uses full test isolation to improve reproducibility and efficiency, while its features include mobile emulation, video recordings, actionability checks, web-first assertions, and configure options for automated re-running of tests when they fail. The framework is used by enterprise and open-source development projects alike, including Adobe Spectrum, Visual Studio Code, and React Navigation, and can be integrated with Checkly's monitoring and debugging experience.
