Selenium

Selenium is an open-source framework for automating web browsers. It provides a suite of tools and libraries to enable automated web application testing.

Key features include:

• Selenium WebDriver: A collection of language-specific bindings to control browsers programmatically, ideal for creating robust regression automation suites.
• Selenium IDE: A record-and-playback tool as a browser add-on for quick bug reproduction scripts and exploratory testing.
• Selenium Grid: Enables distributed test execution across multiple machines and environments, facilitating broad browser/OS compatibility testing.

Selenium is primarily used for automating web applications for testing, but also supports automating web-based administration tasks. It targets QA engineers, developers, and system administrators seeking to automate browser interactions.
