title: No debug trace when running mstest.exe from command line
body: <p>I have a set of mstest unit tests, which use <code>Trace.Write</code> to collect some debugging information. And when I run it from VS2010 and then go to Test Run Details, there's Debug Trace section where I can see all my messages.</p>
  
  <p>But when I run the same test from command line on the build machine, the trace is not recorded.</p>
  
  <p>The things that I've tried:</p>
  
  <ul>
  <li>Make sure that I'm in Debug configuration</li>
  <li><em>/details</em> command line switch with <em>debugtrace</em>, <em>traceinfo</em> etc options</li>
  <li>I know about saving the traces to the file on the disk through the listeners, but I would like to find a solution to write </li>
  </ul>
  
  <p>Has someone had a similar problem?</p>
