ImportError: No module named mock
unittest is a built-in module; mock is an external library (pre-3.3 betas, anyway). After installing mock via pip install, you import it not by using
from unittest.mock import MagicMockbut
from mock import MagicMockEdit: mock has been included in the unittest module (since Python3.3), and can be imported by import unittest.mock.
For Python 2.7:
Install mock:
pip install mockThen in the test code, use this import:
from mock import patch, MagicMock
If you want to support both, Python 2 and Python 3, you can also use following:
import sysif sys.version_info >= (3, 3): from unittest.mock import MagicMockelse: from mock import MagicMockor, if you don't want to import sys
try: from unittest.mock import MagicMockexcept ImportError: from mock import MagicMock
