sharedmock 0.1.0

A multiprocessing-friendly Python mock object

A multiprocessing-friendly Python mock object

Getting started

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: []
