title: How to write text output from nunit in a file?
body: <p>How can I easily capture the NUnit's output (errors, info, anything, really) and write it on files?<br>
  If I could save on multiple files, one for error, and so forth, it would be great.</p>
  
  <p>I aware that I can make use of log4net and create a logging class, but my goal is to use the already great output control that NUnit has.     </p>
  
  <p>And I would want to minimize the code on the tests, keeping them as readable and simple as possible.<br>
  Are there any good practices or a roadmaps for that purpose?<br>
  Like make log4Net capture the output, perhaps?</p>
