If an object's attribute is a partial function, mock.create_autospec will fail while trying to copy the partial functions' details to the mocked function, as the partial function does not have the __name__ attribute.
Example:
import functools
from unittest import mock
class Proxy(object):
def __init__(self, obj):
self.obj
def __getattr__(self, name):
return functools.partial(self.__run_method, name)
def __run_method(self, name, *args, **kwargs):
return getattr(self.obj, name)(*args, **kwargs)
a = mock.Mock()
proxy = Proxy(a)
mock.create_autospec(proxy)
Output:
Traceback (most recent call last):
File "py3_mock_functools.py", line 20, in <module>
mock.create_autospec(proxy)
File "/usr/lib/python3.5/unittest/mock.py", line 2156, in create_autospec
