When I use some_mock.attach_mock(...) and make calls, the resulting some_mock.call_args is None while the some_mock.mock_calls list is not empty.
The code below shows this in Python 3.7.5:
from unittest import TestCase
from unittest.mock import patch, Mock
def foo(value):
return value
class MyObjectTest(TestCase):
@patch(f'{__name__}.foo')
def test_do_something(self, mock_foo):
manager = Mock()
manager.attach_mock(mock_foo, 'foo_func')
foo(3)
print(manager.mock_calls)
print(manager.call_args)
print(manager.call_args_list)
if __name__ == "__main__":
unittest.main()
The print statements return:
[call.foo_func(3)]
None
[]
While the code below (without attach_mock) works fine:
from unittest import TestCase
from unittest.mock import patch, Mock
def foo(value):
return value
class MyObjectTest(TestCase):
@patch(f'{__name__}.foo')
def test_do_something(self, mock_foo):
foo(3)
print(mock_foo.mock_calls)
print(mock_foo.call_args)
print(mock_foo.call_args_list)
if __name__ == "__main__":
unittest.main()
Print statements correctly return:
[call(3)]
call(3)
[call(3)]
I also tested in Python 3.8.0 and got the same result. |
