This document discusses various WebDriver implementations including the Firefox Driver, Internet Explorer Driver, HTML Unit Driver, and other drivers like Chrome Driver and Android Driver. It provides details on the structure, usage, and pros and cons of each driver. The Firefox Driver controls Firefox using a plugin, the Internet Explorer Driver is Windows only, and the HTML Unit Driver is the fastest but may not emulate JavaScript like real browsers.

13. Java Script in HtmlUnit
 HtmlUnit’s Java Script engine

 If web application is tested enabling
JS engine of HTMLUnit, the results
may be different as compare to
other browsers.
