From: Pit Capitain Date: 2006-01-25T17:00:28+09:00 Subject: Re: running unit tests in graphical mode Hi Navya, you have to change two lines in your code: > require 'test/unit/ui/tk/testrunner' Change the preceding line to: require 'test/unit' > class TestRoman < Test::Unit::UI::Tk::TestRunner Change that to: class TestRoman < Test::Unit::TestCase A TestRunner is the thing that is running all your tests, which should be subclasses of Test::Unit::TestCase. To find out how to use another TestRunner, run your script with the option -h: ruby -h Regards, Pit
