title: Run HUnit without output
body: <p>I have a Test:</p>
  
  <pre><code>test1 = TestCase (assertEqual "Bla" 2 (add1 1))
  </code></pre>
  
  <p>And want to run it in another Haskell programm without automatic I/O output which </p>
  
  <pre><code>runTestTT test1
  </code></pre>
  
  <p>would create. I tried</p>
  
  <pre><code>runTestText (putTextToHandle stderr False) test1 
  </code></pre>
  
  <p>but this will still create output. Is there a way (maybe another Handle instead of stderr/stdout) to stop the test from creating output?</p>
  
  <p>I would like to just get the IO Counts to use them at another place.</p>
