type="cite">Hi all,<br>
I am fairly new to mock and I would like to know how to fix an
issue during module imports and scope of functions.<br>
Here is a snippet that explain problem I am dealing with:<br>
<br>
from mock import MagicMock<br>
import sys<br>
sys.func = lambda: 'x'<br>
from sys import func<br>
print func()<br>
# outputs 'x'<br>
sys.func = MagicMock(return_value='mocked_x')<br>
print func()<br>
# outputs 'x', it is not mocked<br>
<br>
How could I fix this?<br>
<br>
Thanks,<br>
Mat<br>

Hey Mathieu,<br>
<br>
Your 7th line changes the value of sys.func (the 'func' attribute on
local variable 'sys') but you haven't changed the value of local
variable 'func'. Modifying one won't affect the other. You'd see the
same behaviour even if MagicMock wasn't involved (e.g assigning
'sys.func' to 0 will not affect the value of 'func' either.)<br>
<br>
From the code you've posted, it's not clear to me what you're trying
to achieve.<br>
<br>
Perhaps you meant to write:<br>
<br>
>>> func = Mock(return_value='mocked')<br>
>>> func()<br>
mocked<br>
<br>
or<br>
<br>
>>> sys.func = Mock(return_value='mocked')<br>
>>> sys.func()<br>
mocked<br>
<br>
Best regards,<br>
