单元测试ASP.NET MVC重定向

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

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

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

解决方法

[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");
    }
}
