Does anyone know a good example of functional testing a Python Tkinter application?

Question

I found a great website that discusses functional testing of a Python GUI application using IronPython: http://www.voidspace.org.uk/python/articles/testing/ , but I want to use Tkinter and have it that makes it difficult to switch between libraries .

Michael shows this example for IronPython:

class FunctionalTest(TestCase):

    def setUp(self):
        self.mainForm = None
        self._thread = Thread(ThreadStart(self.startMultiDoc))
        self._thread.SetApartmentState(ApartmentState.STA)
        self._thread.Start()
        while self.mainForm is None:
            Thread.CurrentThread.Join(100)

    def invokeOnGUIThread(self, function):
        return self.mainForm.Invoke(CallTarget0(function))

... and it’s hard for me to translate this into how I connect to the Tkinter application, which will have a basic configuration:

from tkinter import *
from tkinter import ttk

root = Tk()
ttk.Button(root, text="Hello World").grid()
root.mainloop()

... I think that you will want to run the method on the main root object in the second thread, but I do not see the equivalent method for mainForm.Invoke (). Maybe I'm thinking about it wrong. Perhaps functional testing of GUI applications this way is not so common?
