Hi Mahendra Kumar,
With Telerik Testing Framework you are acting directly on the DOM/Visual tree. This means that it supports all HTML and Silverlight based applications. This is what the majority of all web applications are based. So yes, the Telerik.Web.Mvc controls are fully supported.
Are you experiencing some sort of trouble when trying to automate against Telerik MVC controls? If yes, please provide as much info as possible.
