                This test is applicable only on macOS.

                Test UI contains an empty JFrame. On press of left/right mouse button,
                a PopupMenu will be visible.

                Follow these steps to test the behaviour:

                1. Start the VoiceOver (Press Command + F5) application
                2. Press Left/Right mouse button inside test frame window to open
                   the PopupMenu
                3. VO should announce "Menu" with number of child items of the Popupmenu
                4. Press Up/Down arrow to traverse popupmenu child items
                5. Press Right arrow key to open submenu
                6. VO should announce "Menu" with correct number of child items
                   for the submenu (For e.g. When Submenu-1 is open, VO should announce
                   "Menu 4 items")
                7. Repeat the process for other submenus
                8. Press Pass if you are able to hear correct announcements
                   else Fail""";
