Run code once before and after ALL tests in xUnit.net

Question

TL;DR - I\'m looking for xUnit\'s equivalent of MSTest\'s AssemblyInitialize (aka the ONE feature it has that I like).

Specifically I\'m looking for it

Answer 1

To execute code on assembly initialize, then one can do this (Tested with xUnit 2.3.1)

using Xunit.Abstractions;
using Xunit.Sdk;

[assembly: Xunit.TestFramework("MyNamespace.MyClassName", "MyAssemblyName")]

namespace MyNamespace
{   
   public class MyClassName : XunitTestFramework
   {
      public MyClassName(IMessageSink messageSink)
        :base(messageSink)
      {
        // Place initialization code here
      }

      public new void Dispose()
      {
        // Place tear down code here
        base.Dispose();
      }
   }
}
