try this:

public static void SetContext(this Controller controller)
        {
            var httpContextBase = new Mock<HttpContextBase>();
            var httpRequestBase = new Mock<HttpRequestBase>();
            var respone = new Mock<HttpResponseBase>();
            var session = new Mock<HttpSessionStateBase>();
            var routes = new RouteCollection();
            RouteConfigurator.RegisterRoutesTo(routes);

            httpContextBase.Setup(x => x.Response).Returns(respone.Object);
            httpContextBase.Setup(x => x.Request).Returns(httpRequestBase.Object);
            httpContextBase.Setup(x => x.Session).Returns(session.Object);
            session.Setup(x => x["somesessionkey"]).Returns("value");
            httpRequestBase.Setup(x => x.Form).Returns(new NameValueCollection());
            controller.ControllerContext = new ControllerContext(httpContextBase.Object, new RouteData(), controller);
            controller.Url = new UrlHelper(new RequestContext(controller.HttpContext, new RouteData()), routes);
        }
