Yeah... It does come down to experience. I've found that most sufficiently large projects require a large amount of scaffolding - on a massive project, you can't write a bit of code and compile and run everything on day one, you need to put in place structures and stubs and mocks to get you going. The reality is - All of this, really, ends up being good test code. Rather than create all this throwaway code, you can actually do better by making these tests and stubs. So, a lot of developers are writing a lot of the foundations of a their testing framework and not realising it.
