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 <yourscript.rb> -h
