Test fails saying action parameter doesn't match.

[zagnut999]

I'm trying to write a fluent test that will test the parameter values passed to the action. Below is the code I used and am not getting the results I expected. In the route I am adding overrideImageFormat to the defaults object, but it is not being used by the test. The code below but inside a VS project can be found here: https://www.dropbox.com/s/ao4ksxw6xwsqxxp/MvcRouteTesterIssue.zip?dl=0

    public class ImageTestController : Controller
    {
        public ActionResult Icon(IconTestModel model, ImageFormat overrideImageFormat = null)
        {
            return Content("");
        }
    }

    public class IconTestModel
    {
        public string Name { get; set; }
        public string OverlayName { get; set; }
    }

    [TestMethod]
    public void Test()
    {
        var routes = new RouteCollection();
        var route = routes.MapRoute(
            name: "Icon", url: "Icon/{name}",
            defaults: new
            {
                controller = "ImageTest", action = "Icon",
                overrideImageFormat = ImageFormat.Png,
            }
        );
        route.DataTokens["area"] = "Common";

        routes
            .ShouldMap("/icon/name")
            .To<ImageTestController>(ctrl => ctrl.Icon(new IconTestModel { Name = "name" }, ImageFormat.Png));
    }

I'm having the same issue. basically any Action with optional parameters fails the fluent test because of the way it is reflected back as a defined route value. instead it should be respected as an optional parameter.

I'm still seeing this as an issue. I'm able to use simple syntax, but the lack of strongly typed tests certainly less desirable.
