what is Selenium?

(Selenium)[https://www.seleniumhq.org/] is a web testing framework in which you write tests that simulate user behavior, for example to browse a page, to click a link, open a popup, filling out a form etc. Selenium provides a the (WebDriver protocol)[https://www.seleniumhq.org/docs/03_webdriver.jsp] with which you can write the tests. Libraries for Java, JavaScript, Python, Ruby and other programming languages exist.

Selenium can be run as a standalone server, or you can create a (Selenium Grid)[https://www.seleniumhq.org/docs/07_selenium_grid.jsp#selenium-grid-2-0]. In a grid, one machine takes the role of a hub, a central server to which you execute the tests and with which you register nodes. Nodes are machines that that run multiple instances of a browser and actually execute the tests.
