How to sort a mock object in python?

I am mocking the path attribute of an object that is used for sorting. However, trying to sort objects fails:

    def __lt__(self, other: RealObject) -> bool:
        """Sort based on path."""
>       return self.path < other.path
E       TypeError: '<' not supported between instances of 'MagicMock' and 'MagicMock'

So I tried extending MagicMock, but it still fails:

class MockPath(MagicMock):
    def __init__(self, name: Optional[str] = None, *args, **kw) -> None:
        super().__init__(*args, **kw)
        self.name = name or str(random.randint(1, 10000))

    def __lt__(self, other) -> bool:
        return self.name < other.name

    def __lt__(self, other: RealObject) -> bool:
        """Sort based on path."""
>       return self.path < other.path
E       TypeError: '<' not supported between instances of 'MockPath' and 'MockPath'

How can I allow the mocked objects to sort? It's not important what they sort to, I just don't want it to fail.
