Hmm ... don't quite understand: the cleanup follows the same pattern used across many controls/skin tests 

    @After
    public void cleanup() {
        if (stage != null) {
            stage.hide();
        }

The stage is created at most once per test method, and allows to add more controls in that same test method, it's hidden after running each test. Running the next text, there's no reference to the old .. why should we remove its children also? Or maybe I misunderstand what you are suggesting :)
