   >But haven't you added a new method to SUT just to avoid the coupling?   
      
   Yes, because I have refactored the code in order to decouple.  This is   
   all basic stuff done to retrofit tests onto legacy code (i.e. code   
   without unit tests).  Nothing I'm proposing here is radical or   
   mind-altering, it's pretty standard stuff.  See "Working Effectively   
   with Legacy Code" by Michael Feathers.   
      
   If I were writing this code from scratch, I'd be writing it TDD and it   
   would already be decoupled from it's collaborators without making me   
   use link-time substitution for them.   
      
   Writing manual mocks vs. generating them from an interface   
   specification is orthogonal to decoupling from collaborators.
