Testing for ASP.Net Application<\/h3>\n
Testing for ASP.Net applications can be done with the help of Visual Studio. Visual Studio provides a flexible and efficient way to run your unit tests and view their results in Visual Studio. We write a small piece of code for a particular method to test a particular situation or scenario. A method can have multiple scenarios so we can create multiple test cases for one method.<\/p>\n
Create a project and unit tests manually<\/h3>\n
Steps to add a unit test project to a solution:<\/strong><\/p>\n The unit test project (DemoUnitTesting) is created. After this we create test cases with the help of methods as an example given below:<\/p>\n namespace DemoUnitTesting.Controllers } Case 1: Test passed using System.Text; namespace DemoUnitTesting.Tests.Controllers HomeController controller = new HomeController(); \/\/ create instance of controller \/\/ Act: invokes the method under test \/\/ Assert We can run the unit test either by entering the keyboard combination Ctrl-R, A or by clicking the RunTests as shown below. Status for the test (passed or failed ) is visible on the test explorer window.<\/p>\n\n

\n<\/li>\n<\/ol>\nTo create unit test cases into a project :<\/h3>\n
\nHomeController.cs
\nusing System;
\nusing System.Collections.Generic;
\nusing System.Linq;
\nusing System.Web;
\nusing System.Web.Mvc;<\/p>\n

\n public class HomeController : Controller
\n {
\n public ActionResult TestUnitTesting()
\n {
\n ViewBag.Message = \"Hello Unit Testing\"; \/\/ message for testing
\n return View();
\n }<\/p>\n
\n}
\n<\/code><\/p>\n
\n
\nHomeControllerTest.cs<\/strong><\/p>\n
\nusing System.Web.Mvc;
\nusing Microsoft.VisualStudio.TestTools.UnitTesting;
\nusing DemoUnitTesting;
\nusing DemoUnitTesting.Controllers;<\/p>\n
\n{
\n [TestClass]\n public class HomeControllerTest
\n {
\n [TestMethod]\n public void TestMethod()
\n {
\n \/\/ Arrange : sets the value of the data that is passed to the method under test <\/p>\n
\n string viewbagMessage = \"Hello Unit Testing\"; \/\/expected result <\/p>\n
\n ViewResult result = controller.TestUnitTesting() as ViewResult; <\/p>\n
\n Assert.IsNotNull(result);
\n Assert.AreEqual(viewbagMessage, result.ViewBag.Message); \/\/compare the result
\n }
\n }
\n }
\n<\/code><\/p>\nTesting the Action Result returned by a Controller <\/h3>\n
