New submission from Dylan Semler <dylan.sem...@gmail.com>:
If a MagicMock is created with a spec or spec_set that is a non-list iterable
of strings (like a tuple), calling dir() on said mock produces a Traceback.
Here's a minimum example:
🡒 cat poc.py
from unittest.mock import MagicMock
mock = MagicMock(spec=('a', 'tuple'))
dir(mock)
🡒 python3 poc.py
Traceback (most recent call last):
File "poc.py", line 4, in <module>
dir(mock)
File "/usr/lib64/python3.6/unittest/mock.py", line 677, in __dir__
return sorted(set(extras + from_type + from_dict +
TypeError: can only concatenate tuple (not "list") to tuple
