Thank you very much for linking to those videos. I wasn't previously
aware of them, and they (or at least the first one, which is the
only one I've got through so far) seem very salient to this thread.

I like this quote a lot (at around 21:14 in the first part, from Kent
Beck), which
fits very well with my own feelings on some of this:

"My experience is, if I use TDD, I can refactor stuff.
And then I heard stories people say, well 'I use TDD and
now I can't refactor anything', and I couldn't understand it,
and I started looking at their tests. Well, if you have
mocks returning mocks returning mocks, your test is
completely coupled to the implementation, not the interface,
but the exact implementation of some object, y'know,
three streets away... of course you can't change anything
without breaking the tests."

I look forward to watching the rest.

  cheers,
    rog.
