[New-bugs-announce] [issue21478] mock calls don't propagate to parent (autospec)

Dmitry Andreychuk report at bugs.python.org

New submission from Dmitry Andreychuk:

Calls to autospecced mock functions are not recorded to mock_calls list of parent mock. This only happens if autospec is used and the original object is a function.


import unittest.mock as mock

def foo():

parent = mock.Mock()
parent.child = mock.create_autospec(foo)


Expected output:

It works fine if foo function is substituted with a class.

Initially I came across this problem with patch() and attach_mock() but I simplified it for the demonstration.
