| Currently, the autospec=True argument can be passed to mock.patch, but when trying to make assertions on the call and its arguments, it can fail, as it expects an instance / class instance reference as the first argument (self / cls arguments are not consumed when autospec-ing). Steps to reproduce: >>> import mock >>> from mock.tests import testmock >>> >>> with mock.patch.object(testmock.Something, 'meth', autospec=True): ... smth = testmock.Something() ... smth.meth(mock.sentinel.a, mock.sentinel.b, mock.sentinel.c, mock.sentinel.d) ... smth.meth.assert_called_once_with(mock.sentinel.a, mock.sentinel.b, mock.sentinel.c, mock.sentinel.d) ... Traceback (most recent call last): File "", line 4, in File "/usr/local/lib/python2.7/dist-packages/mock/mock.py", line 318, in assert_called_once_with return mock.assert_called_once_with(*args, **kwargs) File "/usr/local/lib/python2.7/dist-packages/mock/mock.py", line 948, in assert_called_once_with return self.assert_called_with(*args, **kwargs) File "/usr/local/lib/python2.7/dist-packages/mock/mock.py", line 937, in assert_called_with six.raise_from(AssertionError(_error_message(cause)), cause) File "/usr/local/lib/python2.7/dist-packages/six.py", line 718, in raise_from raise value AssertionError: Expected call: meth(sentinel.a, sentinel.b, sentinel.c, sentinel.d) Actual call: meth(<mock.tests.testmock.Something object at 0x7f23e456dcd0>, sentinel.a, sentinel.b, sentinel.c, sentinel.d) Expected result: no AssertionError. |
