title: Mocking a base class method call with Moq
body: <p>I am modifiying a class method which formats some input paramater dates which are subsequently used as params in a method call into the base class (which lives in another assembly).</p>
  
  <p>I want to verify that the dates i pass in to my method are in the correct format when they are passed to the base class method so i would like to Moq the base class method call. Is this possible with Moq?</p>
