我正在尝试模拟一个函数。当我尝试模拟该函数时，core.use_cases.add_owner_to_place模拟不起作用。它不断打印“哎哟”。
我尝试测试一下mocked_add_owner_to_place.called，结果返回False。
有谁知道为什么即使我模拟它它仍然使用真实的函数？
视图.py：
from core.use_cases import add_owner_to_place
class CreatePlace(LoginRequiredMixin, FormView):
template_name = 'place/create_place.html'
form_class = PlaceForm
success_url = reverse_lazy('place_list')
def form_valid(self, form):
place = form.save()
add_owner_to_place(place, self.request.user)
return super(CreatePlace, self).form_valid(form)
测试.py：
from unittest.mock import patch, Mock
@patch('core.use_cases.add_owner_to_place')
@patch('core.forms.PlaceForm.is_valid')
@patch('core.forms.PlaceForm.save')
def test_save_should_be_called(self, mocked_save, mocked_is_valid, mocked_add_owner_to_place):
self.client.post(reverse('place_create'), data={})
self.assertTrue(mocked_save.called)
use_cases.py：
def add_owner_to_place(place, user):
print('Ouch')
