Might mock.MagicMock be given a type parameter?

Feature or enhancement

Proposal:

In the case of

class MyClass:
  def method_that_exists_on_my_class(self):
    pass

my_mock_thing = mock.create_autospec(MyClass)
my_mock_thing.method_that_exists_on_my_class()
my_mock_thing.method_that_does_not_exist_on_my_class()
my_mock_thing.method_that_exists_on_my_class.assert_called_once()
my_mock_thing.method_that_does_not_exist_on_my_class.assert_called_once()

it would be nice if the type of my_mock_thing were mock.MagicMock[MyClass] (instead of "raw" mock.MagicMock) so that type-checkers could alert me that my call to my_mock_thing.method_that_does_not_exist_on_my_class is a flaw in my test.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

(I looked around among both open and closed issues and didn't see anything on this topic; apologies if I overlooked an already-ongoing discussion...)

该提案围绕 mock.MagicMock 和 mock.create_autospec 展开；首先定位这些入口点，并检查当前如何对 mock 进行类型标注。然后确定与 autospec 属性访问相关的测试。当类型检查器能够标记 autospecced mock 上不存在的方法，同时保留对有效方法的访问时，即视为完成。
