Mocking controller UrlHelper

I'm having problems retrieving the route url from controller.RouteUrl(routeName) method. Here is my code for mocking the urls in my test method:

//Arrange
...
//Mock routes
var routes = RouteTable.Routes;

routes.Clear();
routes.MapRoute(
    "AdminPaymentResult",      // Route name
    "Payment/Result");         // URL with parameters

routes.MapRoute(
    "AdminPaymentCancel",      // Route name
    "Payment/Cancel");         // URL with parameters

_controller.SetFakeUrlHelper(routes);
...

where the method SetFakeUrlHelper is defined as:

public static void SetFakeUrlHelper(this Controller controller, RouteCollection routes)
{
    var fakeHttpContext = FakeHttpContext();
    var requestContext = new RequestContext(fakeHttpContext, new RouteData());
    controller.Url = new UrlHelper(requestContext, routes);
}

and the method FakeHttpContext is defined as:

public static HttpContextBase FakeHttpContext()
{
    var request = new Mock<HttpRequestBase>();
    var response = new Mock<HttpResponseBase>();
    var session = new Mock<HttpSessionStateBase>();
    var server = new Mock<HttpServerUtilityBase>();

    var context = new Mock<HttpContextBase>();

    context.Setup(ctx => ctx.Request).Returns(request.Object);
    context.Setup(ctx => ctx.Response).Returns(response.Object);
    context.Setup(ctx => ctx.Session).Returns(session.Object);
    context.Setup(ctx => ctx.Server).Returns(server.Object);

    return context.Object;
}

The problem is that when in my controller action I call

public ActionResult MyAction()
{
    ...
    var callBackUrl = Url.RouteUrl("AdminPaymentResult");
    ...
}

I get an empty string instead of "Payment/Result" as expected... Thanks in advance

You should mock the ApplyAppPathModifier method on the response which is internally used by the UrlHelper. So just add the following line inside your FakeHttpContext method and you will be good to go:

response
    .Setup(x => x.ApplyAppPathModifier(It.IsAny<string>()))
    .Returns<string>(x => x);
