Two prominent open-source browser automation tools have emerged as leaders in test automation. Selenium and Playwright empower developers and QA professionals to create robust, automated tests for web applications. While both tools support a wide range of browsers, including older versions, they differ significantly in their approach and features. Selenium is a more mature tool with an extensive ecosystem and broad language support, but it requires users to write more code to get an automated test working. On the other hand, Playwright is a modern framework that allows users to write code from the start, making it unnecessary to write boilerplate code. Playwright excels at handling complex, dynamic web applications with features like auto-waiting and network interception. Its use of WebSocket communication and single browser instance for multiple contexts results in faster test execution. Additionally, Playwright simplifies cross-browser testing workflows with built-in support for Chromium and any modified versions by the Playwright team. The choice between Selenium and Playwright depends on factors such as broad browser compatibility required, language flexibility prioritized, leveraging existing infrastructure and expertise, mobile app testing necessity, need for extensive third-party integrations, and team preferences for modern JavaScript/TypeScript ecosystem.
