Hi,

I have the following program written and when I run It comes up saying zero tests.
what more should include in the code below for it to run in graphical mode.
Please Help

require 'test/unit/ui/tk/testrunner'
class Roman
    MAX_ROMAN = 4999
    
    def initialize(value)
        if value <= 0 || value > MAX_ROMAN
            fail "Roman values must be > 0 and <= #{MAX_ROMAN}"
        end
        @value = value
    end
    FACTORS = [["m", 1000], ["cm", 900], ["d", 500], ["cd", 400],
                         ["c", 100], ["xc", 90], ["l", 50], ["xl", 40],
                         ["x", 10],["ix" ,9], ["v", 5], ["iv", 4],
                         ["i", 1]]
                         
    def to_s
        value = @value
        roman = "";
        for code, factor in FACTORS
            count, value = value.divmod(factor)
            roman << (code * count)
        end
        roman
    end
end
class TestRoman < Test::Unit::UI::Tk::TestRunner
    def test_simple
        assert_equal("i", Roman.new(1).to_s)
        assert_equal("ix", Roman.new(9).to_s)
        assert_equal("ii", Roman.new(2).to_s)
        assert_equal("iii", Roman.new(3).to_s)
        assert_equal("iv", Roman.new(4).to_s)
    end
end

Thanks,
Navya.

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

Regards,
Pit

require 'test/unit/ui/tk/testrunner'

require 'test/unit'

class Roman

   (snip)

end
class TestRoman < Test::Unit::UI::Tk::TestRunner

class TestRoman < Test::Unit::TestCase

    def test_simple
        assert_equal("i", Roman.new(1).to_s)
        assert_equal("ix", Roman.new(9).to_s)
        assert_equal("ii", Roman.new(2).to_s)
        assert_equal("iii", Roman.new(3).to_s)
        assert_equal("iv", Roman.new(4).to_s)
    end
end

When the filename is 'test_roman.rb',
please call "ruby test_roman.rb --runner=tk".
