Testing MVC 3 Applications with xUnit.net

---

Microsoft Visual Web Developer Express edition doesn’t support MS Test. But we can create test with the help of xUnit.net testing framework mainly for MVC Web Applications.

1. Start Visual Web Developer 2010 Express and create a MVC 3.0 Web Application

   

2. Select Internet Application project template and check the Create a unit test project. By default the test project name will be <Project Name>.Tests and the test framework will be xUnit.net.

   

   The project structure will be as shown below

   

3. Right click on Controllers folder and select  Controller from Add menu.

   

4. Set some text to the Message property of ViewBag as shown in line number 12

5. Create a class in the Test project and name it EmployeeControllerFacts.cs which will hold the test cases for Employee Controller.
   

   

   
   
6. Build the test project and open the xUnit test runner from the installation folder. Add the test project dll with the help of Open menu from Assembly toolbar.
   

   

   
   
7. Click the Run Selected button to execute the test methods
