It's that simple, at least for me.

That one line is all that's in unit_tests.rb, which I run with 'ruby
unit_tests.rb'.

Then, in the tests directory are a bunch of files like

require 'test/unit'
require 'what_i_am_testing'

class MyTestClass < Test::Unit::TestCase
  def test_blah
    # ...
  end
end


It's very nice not to have to do any other crufty setup-type things to
run unit tests.  And so my question was how can I easily modify my
current way of unit tests to run tests in a graphical mode.
