The idea is that an artifact is just a definition of a file. We use the 
constructor to define one, and we use the methods to actually operatore 
on it. I originally implemented this behaviour, but there was a case – 
which I can't remember right now – where this wasn't wanted. Overall, it 
should be clearer to the test writer to calls operational methods 
explicitly.
