WebDriver for Internet Explorer
The W3C WebDriver API is a platform and language-neutral interface and wire protocol allowing programs or scripts to control the behavior of a web browser.
WebDriver support is available for Internet Explorer (IE6 through IE11) via the open source IEDriverServer.exe provided by the Selenium Project.
