C# - Bootstrapping xUnit

Note: This guide assumes you have .NET Core installed.

1. Create a new project folder for the code.

   (Assuming the project is named new_kata)

   dotnet new xunit -o new_kata
   cd new_kata
   rm .\UnitTest1.cs

2. Inside the project folder (new_kata), create a test file (TestArithmetic.cs) with the following content:

   using System;
   using Xunit;
   
   namespace new_kata
   {
       public class TestArithmetic
       {
           [Fact]
           public void TestThat1Plus2Is3()
           {
               Assert.Equal(3, Arithmetic.Add(1, 2));
           }
       }
   }

3. Inside the project folder (new_kata), create the implementation file (Arithmetic.cs) with the following content:

   namespace new_kata
   {
       public static class Arithmetic
       {
           public static int Add(int x, int y) => x + y; 
       }
   }

4. Run the test.

   dotnet test

   You should see this:

   Starting test execution, please wait...
   
   Total tests: 1. Passed: 1. Failed: 0. Skipped: 0.
   Test Run Successful.
