Sorry for asking a dummy problem. I just solve it by changing the string quote
from double to single. The problem is that doctest treat double quote string
and single quote string as different value!
>>> s = "<MYBT@ToggleButton+Button>:"
>>> test_kivy_class(s)
'<MYBT@ToggleButton+Button>:' < change from double quote to single
>>> s = "<MYBT>"
>>> test_kivy_class(s)
'<MYBT>' < change from double quote to single
