单元测试 ASP.NET MVC 重定向

如何对 MVC 重定向进行单元测试？

public ActionResult Create(Product product)
{
    _productTask.Save(product);
    return RedirectToAction("Success");   
}

public ActionResult Success()
{ 
     return View();
}

Is Ayende's http://www.ayende.com/Blog/archive/2007/12/13/Dont-like-visibility-levels-change-that.aspx方法仍然是最好的方法，预览 5：

 public static void RenderView(this Controller self, string action) 
 {
    typeof(Controller).GetMethod("RenderView").Invoke(self,new object[] { action} ); 
 }

必须这样做似乎很奇怪，特别是当 MVC 团队表示他们正在编写可测试的框架时。

[TestFixture]
public class RedirectTester
{
    [Test]
    public void Should_redirect_to_success_action()
    {
        var controller = new RedirectController();
        var result = controller.Index() as RedirectToRouteResult;
        Assert.That(result, Is.Not.Null);
        Assert.That(result.Values["action"], Is.EqualTo("success"));
    }
}

public class RedirectController : Controller
{
    public ActionResult Index()
    {
        return RedirectToAction("success");
    }
}
