I do not fully understand what you're are trying to achieve with your code,
but this observation might help you anyway:

[...]

[...]

[...]

In both cases you do the eqivalent of

b = Button(..., command=None)

as both TestCases() and hostTC() do not explicitly return a value.
You probably want the buttons to invoke TestCases() or hostTC(), and you
therefore must omit the trailing (), e. g.:

b = Button(root, text='OK!',command=hostTC)
