I had never thought about calling a single method on the SUT multiple times as duplication. I'll have to spend some more time thinking about that.
Perhaps I should write this up somewhere. ?The usual example I give when teaching is using Java and moving a method from a static call no a non-static call. ?The test suite now needs to be updated in multiple places, hence the duplication.
Please do. Feel free to e-mail me or post a link to the writeup once it's done :).
