New submission from James Marchant <marchant...@gmail.com>:
When using `create_autospec()` to create a mock object, it doesn't respect values passed through in the style described for passing mock configurations in the Mock constructor (https://docs.python.org/3.8/library/unittest.mock.html#unittest.mock.Mock.configure_mock). Instead, they seem to get discarded somewhere here (https://github.com/python/cpython/blob/77bab59c8a1f04922bb975cc4f11e5323d1d379d/Lib/unittest/mock.py#L2693-L2741). Here's a simple test case: ``` from unittest.mock import create_autospec class Test: def test_method(self): pass autospec_mock = create_autospec(Test, instance=True, **{"test_method.side_effect": ValueError}) # Should throw a ValueError exception autospec_mock.test_method() # Assign manually autospec_mock.test_method.side_effect = ValueError # Throws as expected autospec_mock.test_method() ``` ---------- components: Tests messages: 412898 nosy: marchant.jm priority: normal severity: normal status: open title: create_autospec() doesn't respect configure_mock style kwargs type: behavior versions: Python 3.10, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46690> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
