Selenium WebDriver

Selenium WebDriver is an open-source tool used for automating web browser interactions, enabling developers and testers to write scripts in various programming languages (such as Java, Python, C#, and Ruby) to control and test web applications.

Unlike its predecessor, Selenium RC, WebDriver interacts directly with the browser without the need for a server, offering faster execution and more reliable performance. It supports a wide range of browsers and operating systems, allowing for cross-browser testing and scalable test automation.

Selenium WebDriver is integral to modern automated testing practices, integrating seamlessly with testing frameworks and continuous integration tools to facilitate robust, end-to-end testing of web applications.
