🎤 Intro Line
Selenium 4 advances with W3C standard compliance, streamlined Selenium Grid, and enhanced tooling for more sophisticated testing over Selenium 3.
3 Points Compared and Contrasted between Selenium 3 and 4.0
- Architecture: Selenium 3 uses the JSON Wire Protocol for communication between the client and server, while Selenium 4 adopts the W3C WebDriver Protocol, offering more standardized communication and improved browser interaction.
- Selenium Grid: In Selenium 3, starting the Hub and Node required separate processes, whereas Selenium 4 integrates both in a single jar file, simplifying setup and offering an optimized, scalable grid with a new GUI and Docker support.
- IDE and Tooling: Selenium 4 enhances the Selenium IDE with additional features like the SIDE Runner for parallel tests and improved user experience. It also introduces new capabilities like relative locators and Chrome DevTools Protocol integration for more advanced testing scenarios.
