I haven't spent enough time with it yet to know, but I suspect that surface mocking (what is usually called stubbing in this community) is going to get harder with the demeter violations. OTOH, I guess as there is more structure to a query, it might be easier to create a more general & dynamic mock library for it - something like lafcadio's mocking library or fakefs. With a mocking library like that out there, we'll have faster test suites. I'm hoping that it totally obliviates the need for a library like guillotine (http://github.com/smtlaissezfaire/guillotine).
