Selenium

Automates web browsers for testing purposes.

You can use Selenium for automating web browsers to create robust, browser-based regression automation suites and tests. It's particularly useful for developers and QA engineers to automate web applications for testing purposes. One standout feature is its support for multiple browsers (Chrome, Firefox, IE, etc.) and operating systems (Windows, Mac, Linux). Practical use cases include running tests in parallel, integrating with CI/CD pipelines, and reducing manual testing efforts.
