Hi all,
I am fairly new to mock and I would like to know how to fix an issue during
module imports and scope of functions.
Here is a snippet that explain problem I am dealing with:

from mock import MagicMock
import sys
sys.func = lambda: 'x'
from sys import func
print func()
# outputs 'x'
sys.func = MagicMock(return_value='mocked_x')
print func()
# outputs 'x', it is not mocked

How could I fix this?
