Writing tests

Time to write some tests. As I mentioned earlier in the chapter, we won't create tests for the entire site; we will leave that to you to finish later if you want to. This is just to get a feel for how to write tests:

1. Right-click and select MyBlog.Shared.Tests, then select Add | New folder. Name the folder Pages.

   This is just so we can keep a bit of a structure (the same folder structure as the project we are testing).

2. Select the Pages folder. Press Shift + F2 to create a new Razor component and name the file IndexTest.cs. Just remember not to name it the same as the component we are testing; otherwise, it will be hard to make sure we are testing the right one.
3. Open IndexTest.cs and add the bUnit namespace:

   using Bunit;
   using Microsoft.Extensions.DependencyInjection;
   using MyBlog.Data.Interfaces;
   using Xunit;

4. Inherit from TestContext by adding the following code:

       public class IndexTest: TestContext
       ...
