You can know how to test the view returned by a controller action, how to test the View Data returned by a controller action, and how to test whether or not one controller action redirects you to a second controller action.

Select Internet Application from New ASP.NET MVC3 Project template and select Visual Studio Unit Test for the Test Framework.

Delete pre-existence file from a Controller folder that exists in .Tests extension.

ProductController.cs

using System;

using System.Web.Mvc;

namespace Store.Controllers

{

     public class ProductController : Controller

    {

         public ActionResult Index()

         {

            throw new NotImplementedException();

         }

         public ActionResult Details(int Id)

         {

            return View("Details");

         }

    }

}

After creating a Controller, create a unit test for the controller:

ProductControllerTest.cs

using System.Web.Mvc;

using Microsoft.VisualStudio.TestTools.UnitTesting;

using Store.Controllers;

  

namespace StoreTests.Controllers

{

    [TestClass]

     public class ProductControllerTest

    {

         [TestMethod]

         public void TestDetailsView()

         {

            var controller =  new ProductController();

            var result = controller.Details(2) as ViewResult;

            Assert.AreEqual("Details", result.ViewName);

  

         }

    }

}

If ProductController returns the matched View the result will come Passed else the result will be Aborted. Our Product controller returns the matched View that’s why Result comes Passed.

The above process indicates how to test the View returned by the Controller action with the help of the Visual Studio Unit Test project.
