I have a feeling the only reason it is so simple for you it that it uses
Test::Unit::UI::Console::TestRunner by default.  I think in order to run test
in graphical mode you're going to have to do something like I did to
specifically tell it to use Test::Unit::UI::Tk::TestRunner or one of the other
GUI TestRunners.  Of course I'd love it if someone could show us a simpler way
than what I have done.
