Exactly.  My main problem with a bottom-up approach is that you're
basically speculating how code will be used.  I've seen people argue
that as long as you have good design skills it really isn't an issue.
However, I much prefer to let my actual usage drive the design, and
then use my design skills to shape it even further.  Simply put, you
have more information, allowing you to make better decisions.

I don't use the scaffolded tests at all.  I'm sure a part of it is
Not-Invented-Here syndrome.  Ruby is so lightweight and expressive
that I think it's acceptable to write that stuff from scratch rather
than use scaffolding.  More importantly though, I'm addicted to
building up behavior in tiny steps.
