Subject: How do I do automated testing of class dependencies?

I've been using RubyUnit for my automated testing, and I'm happy with
it. There's one thing that keeps tripping me up, though: If an
individual file is missing a necessary require, it's possible for this
to slip through my tests and get into production code.

Let's say I have a class A that requires class B, but I forgot to put
in a "require 'B'" statement in A. This will be found if I run

> runtest.rb A.rb

but possibly not if I run

> runtest.rb *.rb

.... if, say, another class loads B.rb before A.rb is run.

Does anybody have any good solutions for this? Thanks.
