Selenium

Selenium is a powerful framework for automating web applications across various browsers and platforms. Its core components include Selenium WebDriver, which allows for direct communication with web browsers for executing tests, and Selenium Grid, which enables parallel test execution across multiple environments to speed up testing processes. Selenium supports multiple programming languages, including Java, C#, Python, and Ruby, allowing developers to write tests in the language of their choice. It also provides features for handling dynamic web elements, managing cookies, and simulating user interactions such as clicks and keyboard inputs. The framework is widely used for functional testing, regression testing, and cross-browser testing in web development.
