Test::Unit 2.x also supports that usage with natural Ruby
syntax:

  # From http://test-unit.rubyforge.org/svn/trunk/sample/test_user.rb

  class UserTest < Test::Unit::TestCase
    def setup
      @user = "me"
    end

    def test_full_name
      assert_equal("me", @user)
    end

    class ProfileTest < UserTest
      setup
      def setup_profile
        @user += ": profile"
      end

      def test_has_profile
        assert_match(/: profile/, @user)
      end
    end
  end


Thanks,
