Feature or enhancement

Large parts of the :mod:tkinter public API have little or no direct test coverage. Widget configuration options are tested fairly thoroughly via the AbstractWidgetTest framework in Lib/test/test_tkinter/test_widgets.py, but many widget methods and the per-element configuration surfaces (tags, embedded images and windows, marks, etc.) are not exercised at all.

For example, before this issue test_text.py tested only a handful of Text methods (debug, search, search_all, count), leaving indices, content manipulation, marks, tags, undo/redo, dump, embedded images and windows, peers, geometry and the tag/image/window configuration options untested.

The goal is to incrementally add tests for the untested tkinter API, widget by widget and method by method:

• Text — methods and tag/image/window option configuration (in progress).
• Canvas — items, tags, coords, scanning, postscript, and item options.
• Listbox, Entry, Spinbox, Menu — selection, indices, item options.
• Misc/Wm — window manager, clipboard, selection, grab, event and winfo methods.
• Geometry managers (pack/place/grid) query methods.
• ttk widgets, Style, Treeview.

This complements the related audit of Tk commands that are only partially wrapped by tkinter.
