.Net standard test internal methods

 如果想在 .Net standard 測試 internal 方法有兩種做法

1. 在要被測試的類別上加 tag
   

     [assembly:InternalsVisibleTo("Unit test 的專案名")]
     namespace XUnitAndFluentAssertionDemo
     {
      internal class Hello {   
      }
     }
     

   
   每個有 internal 方法要測試的類別，都要加這個 tag
2. 在 project file 加 attribute
   

  <ItemGroup\>
    <AssemblyAttribute Include="System.Runtime.CompilerServices.InternalsVisibleTo">
        <_Parameter1>$(AssemblyName).Tests</_Parameter1>
    </AssemblyAttribute>
	</ItemGroup\>
  




只需做一次整個專案都會有這個設定
