title: xunit add info to output
body: <p>Does anyone know how to add additional info to the output console when running xUnit tests?</p>
  
  <p>I'm using testdriven.net, but I don't think that is where my answer lies.</p>
  
  <p>I am using a <code>IUseFixture</code> (actually <code>IClassFixture</code> from 2.0) to maintain data between tests.  When a test fails I want to output some of that contextual data along with the failure and the stack trace that you usually get.</p>
  
  <p>Does anyone know of a hook I can use?</p>
