Unit Testing MVC 4 RedirectToAction

Question

I am trying to unit test the redirection of my controller in MVC 4 .Net 4.5. Here is an example:

    [TestMethod]     public void Register_PassValidModel_RedirectToHomeIndexShouldBeTrue()     {         //Arrange         var registerModel = new RegisterModel         {             Email = "[email protected]",             Password = "password"         };          //Assign         var result = _controller.Register(registerModel) as RedirectToRouteResult;          //Assert         result.RouteValues["Action"].ShouldBeEqual("Index");         result.RouteValues["Controller"].ShouldBeEqual("Home");     } 

Here is the controller:

    [HttpPost]     public ActionResult Register(RegisterModel model)     {          if (ModelState.IsValid)         {             var userToRegister = new User { Email = model.Email, Password = model.Password };             var service = new UserService(_userRepository);              User user = service.RegisterUser(userToRegister);              if (user.UserErrorMessages.Count != 0)             {                 user.UserErrorMessages.ForEach(x => ModelState.AddModelError("", x));                 return View(model);             }              SetCookie(model.Email);              return RedirectToAction("Index", "Home");         }         return View(model);     } 

The issue the variable result in the Unit Test is null. I found this code from someone who was working on a MVC 2 project and it seemed to work for him. Has something changed with MVC 4?

Thanks in advance!

Try this one hope it will useful for you

 var result= (RedirectToRouteResult)controller.Register(registrModel);             result.RouteValues["action"].Equals("Index");            result.RouteValues["controller"].Equals("Home");             Assert.AreEqual("Index", action.RouteValues["action"]);            Assert.AreEqual("Home", action.RouteValues["controller"]);
