WebDriver is a remote control interface that enables introspection and control of user agents. It provides a platform- and language-neutral wire protocol as a way for out-of-process programs to remotely instruct the behavior of web browsers. To have the ability to write instruction sets that can be run interchangeably in many browsers on different platforms is critical to deliver a consistent experience to users. With the new wave of developments on the web platform, the increase diversity in devices and demands for real interoperability between the technologies, WebDriver provides tooling for cross-browser testing. Provided is a set of interfaces to discover and manipulate DOM elements in web documents and to control the behavior of a user agent. It is primarily intended to allow web authors to write tests that automate a user agent from a separate controlling process, but may also be used in such a way as to allow in-browser scripts to control a — possibly separate — browser.

We will also look at how to integrate your local testing environment with commercial tools like the ones discussed in the previous article. Selenium is the most popular browser automation tool. There are other ways, but the best way to use Selenium is via WebDriver, a powerful API that builds on top of Selenium and makes calls to a browser to automate it, carrying out actions such as "open this web page", "move over this element on the page", "click this link", "see whether the link opens this URL", etc. This is ideal for running automated tests. How you install and use WebDriver depends on what programming environment you want to use to write and run your tests. Most popular environments have available a package or framework that will install WebDriver and the bindings required to communicate with WebDriver using this language, for example, Java, C , Ruby, Python, JavaScript Node , etc. Different browsers require different drivers to allow WebDriver to communicate with and control them. See Platforms Supported by Selenium for more information on where to get browser drivers from, etc.
