screen, gui tests must be 'guarded' by "requires('gui')" in a setUp
function or method. This will typically be setUpClass.
-All gui objects must be destroyed by the end of the test, perhaps in a tearDown
-function. Creating the Tk root directly in a setUp allows a reference to be saved
-so it can be properly destroyed in the corresponding tearDown.
+To avoid interfering with other gui tests, all gui objects must be destroyed
+and deleted by the end of the test. If a widget, such as a Tk root, is created
+in a setUpX function, destroy it in the corresponding tearDownX. For module
+and class attributes, also delete the widget.
