title: How do you check a mock was called with a Seq irrespective of order
body: <p>I have a method, which has been mocked, and takes a Seq as a parameter.  </p>
  
  <p>I want to check the method was called with a Seq with the same contents, but irrespective of order.  </p>
  
  <p>eg something like:</p>
  
  <pre><code>myMethod(Seq(0,1)) wasCalled once
  </code></pre>
  
  <p>which passes if we called <code>myMethod(Seq(1,0))</code></p>
