I guess I'm still learning ruby.

While looking through the test code I realized I don't see what
actually _runs_.

My tests extend Test::Unit::TestCase, and define tests as

def test_sometestname
# some testing stuff
end

I scanned Test::Unit::TestCase and I see a bunch of function
definitions, but I don't see what runs. I guess I'm looking for a
method or piece of code that starts running, initializes things, finds
the test_* test methods and starts running them.

It's probably staring me in the face. Please point it out to me.

Thank you.
