Unit testing controller action which redirects to another action

I am following TDD approach to develop my MVC website. I have a PaymentController which is going to have an action method MakePayment which I am testing using a test method as given below:

[TestMethod]
public void MakePaymentLoad()
{
    PaymentController payController = new PaymentController();
    ViewResult payResult = payController.MakePayment() as ViewResult;
    Assert.IsNotNull(payResult);
}

[TestMethod]
public void MakePaymentResult()
{
    PaymentController payController = new PaymentController();
    Payment payment = new Payment {
        BillerId = 1,
        PayAmt = 1.0,                
        PayDt = DateTime.Now,
        ConfCode = null,
        BillAccount = "123",
        PayStatus = 1,
        FeeStatus = 1,
        Platform =1
    };
    ViewResult payResult = payController.MakePayment(payment) as ViewResult;
    PaymentResult result = payResult.Model as PaymentResult;
    Assert.IsNotNull(result.ConfCode);            
}

In the above given test methods MakePaymentLoad only checks if the view is rendered and MakePaymentResult checks out if the confirmation code is present in the view model.

My action methods are given below:

[HttpPost]
public ActionResult MakePayment(Payment payment)
{
    PaymentResult payResult = new PaymentResult {
        ConfCode = "123"
    };
    if (true)
    {
        TempData["ConfCode"] = "123";
        return RedirectToAction("Confirmation");
    }
    return View(payment);
}

public ViewResult MakePayment()
{            
    return View();
}

public ActionResult Confirmation()
{
    PaymentResult result = new PaymentResult {
        ConfCode = Convert.ToString(TempData["ConfCode"])
    };
    return View(result);
}

The MakePaymentLoad passes as it only check if the view is rendered whereas MakePaymentResult fails miserably as the result of action method is null because of the use RedirectToAcion inside MakePayment's post version. Please let me know how to fix this.

you should test it like following

var payResult = (RedirectToActionResult)payController.MakePayment(payment)

Assert.AreEqual("Confirmation", action.RouteValues["action"]);

As you are returning redirect result, you can't expect a model in return.
