sending a Safari test to a node with OSX and the Safari webdriver).įor larger projects, running a lengthy test suite in series can be time consuming. The hub will delegate each test to a node that has the requested capability (e.g. A test suite can then be run against the grid, with each test run on multiple browsers and operating systems. This makes it possible to set up a grid consisting of servers (or virtual machines) running Linux, OSX, and Windows. Selenium runs on Java and is compatible with all major operating systems.

The nodes and hub can be run on the same computer or server, or can be located on separate Linodes. However, Selenium can also be configured as a grid, with multiple nodes communicating with a central hub. This can make it more complicated to get running, but allows you to test your application’s behavior on exactly the platforms that users are likely to need.įor many applications, the Selenium standalone server is sufficient. In contrast to similar tools such as Nightmare.js, Selenium can run tasks or tests on any version of any major browser. It is most often used for testing web applications, but can also be used to automate any task that a web browser can perform. Selenium is a browser automation library with bindings for most common programming languages.
