title: Moq verify method called without mocking implementation
body: <p>Currently we use Moq to verify that a method has been called with the correct parameters, however this requires the method to actually be mocked resulting in loads of bloat in the class. I would rather use the actual implementation.</p>
  
  <p>Can I use Moq to default to the implementation if it hasn't been <code>SetUp</code>? Or is there an alternative way to verify the method has been called?</p>
