I wouldn't call that ideal, either.

I would probably have test() functions in numpy.__init__ and
scipy.__init__ which would internally import the Tester, print out
these messages, then run Tester().test(*args, **kwds). I don't see a
real need for this information to be in the Tester class itself, just
the convenience {numpy,scipy}.test() functions.
