Selenium
Selenium automates browsers for testing and other web application workflows.
About Selenium
Selenium is a browser automation tool designed primarily for automating web application testing, with additional support for automating repetitive web-based administrative tasks. It offers three core components: Selenium WebDriver, which uses language-specific bindings to create robust, scalable, and distributable custom browser automation scripts; Selenium IDE, a standalone tool for quick bug reproduction and exploratory testing via record-and-playback; and Selenium Grid, which enables distributed test execution across multiple machines and centralized management of tests across diverse browser and operating system combinations.
