Shoulda sits on top of Test::Unit and may be helpful. Something like 
this:

class MyTest < Test::Unit::TestCase
  context "top level" do
    setup do
      @stuff = ...
    end

    should "test something at top level" do
      assert_equal 123, @stuff.size
    end

    context "inner level" do
      setup do
        @more_stuff = ...
      end

      should "test more" do
        assert_equal @stuff.size, @more_stuff.size
      end
    end
  end
end
