Thanks for the response Eric. I looked up add_assert but it didn't
really help that much since the aggregate object (SubAssertObj) is in a
diff context then the original TestStuff testcase.

However I did do something similar to your other suggestion. I threw the
validation code in a module and I'm now include'ing in my individual
testcases as needed.

Thanks again.

See add_assertion in Test::Unit::TestCase and Test::Unit::Assertions

Why not write it like this:

class TestStuff < Test::Unit::TestCase

   def test_stuff
     util_verify_stuff 'please work'
   end

   def util_verify_stuff(str)
     assert_equal 'please work', str
   end

end

And then use subclassing to reuse common functionality?
