Seems fine.

  $ cat test.rb
  class TC_Foo < Test::Unit::TestCase
    def setup
      puts "Foo#setup"
    end

    def test_method1
      assert_nothing_raised {puts "Foo#test_method1"}
    end

    def test_method2
      assert_nothing_raised {puts "Foo#test_method2"}
    end
  end

  class TC_Goo < TC_Foo
    def setup
      puts "Goo#setup"
    end

    def test_method1
      assert_nothing_raised {puts "Goo#test_method1"}
    end

    # TC_foo#method2 will get called for

  end
  $ testrb -vs test.rb
  Foo#setup
  Foo#test_method1
  Foo#setup
  Foo#test_method2
  Goo#setup
  Goo#test_method1
  Goo#setup
  Foo#test_method2
