title: How to test for sometimes fails?
body: <p>I'm trying to write a unit test for a module that will give me a random list of numbers given certain criteria.</p>
  
  <p>The particular test I'm writing is a reshuffle of the original sequence. I'm testing that</p>
  
  <ul>
  <li>The sequences are the same length</li>
  <li>The sequences have the same values</li>
  <li>The sequences are not in the same order</li>
  </ul>
  
  <p>The problem with this is that sometimes the sequences <em>are</em> in the same order. What would be the best way to deal with this?</p>
  
  <p>I'm using NUnit (but could use another test framework if it helps).</p>
