A multiprocessing-friendly Python mock object
The SharedMock object has an interface similar to Python’s own
unittest.mock.Mock. The main difference is that the state of a
SharedMock object is shared among subprocesses. This allows you to
easily test interactions of subprocesses with your mock instance.
from sharedmock.mock import SharedMock
sharedmock = SharedMock()
subprocess = mp.Process(target=sharedmock,
args=('fancyArg',))
subprocess.start()
subprocess.join()
subprocess.terminate()
expected_calls = [call('fancyArg')]
sharedmock.assert_has_calls(expected_calls,
same_order=False)If the SharedMock were to be replaced by a unittest.mock.Mock in
the example above, the assertion would fail. The interaction with the
unittest.mock.Mock object would not get propagated to your test
code:
E AssertionError: Calls not found.
E Expected: [call('fancyArg')]
E Actual: []The entire source code is available on GitHub.
