title: Is it possible to customize NUnit XML output?
body: <p>I'm looking at NUnit XML output right now and wonder if it's possible to generate the output <strong>for failures only</strong>.</p>
  <p>I mean, if a test passes OK, no XML output gets generated for it at all.</p>
  <p>XSLT is not an option here. <strong>I don't want XML output for passed tests at all</strong>: if I don't need the details about the passed tests, I don't want the system to spend time generating those details.*</p>
  <p>The idea is, XML output tend to be quite large if you have a lot of tests, but 80% of the time you're after failures anyway. For such cases, I'd like to run my tests in such a way that only information on failures get generated.</p>
