Django前置和后置信号模拟

由于某些原因，在视图中存在前置和后置信号的阻止

def view(*args):
    # disable pre- and post-save signals for MyModel
    my_model_object.save()
    # anable pre- and post-save signals for MyModel

我如何模拟django pre_save和post_save信号来检查MyModel是否调用了它们？（没有任何接收者检查它是否未被调用）

我试过这个，但不起作用：

def MyTestCase(TestCase):
    def setUp(self):
      super(MyTestCase, self).setUp()
      self.patcher = patch('django.db.models.signals.pre_save')
      self.mocked_pre_save = self.patcher.start()

    def test_pre_save_signal_not_sent(self):
      self.admin_post(url, post_data)
      pre_save_senders_list = [arg[1]['sender'] for arg in mocked_pre_save.send.call_args_list]
      self.assertNotIn(MyModel, pre_save_senders_list)

我认为你应该提供实际的测试
