is there a type for a factory that returns fixtures?

[delfick]

Hello,

I like the pattern of test harnesses that can generate fixtures, i.e.

from my_test_harneses import SomeManagerOfSomething

the_manager = SomeManagerOfSomething.make_fixture(option1=1, option2=2)

def test_it_works(the_manager: SomeManagerOfSomething):
   ...

Which ends up being like

import typing as tp
import pytest

class SomeManagerOfSomething:
    @classmethod
    def make_fixture(cls, *, option1: int, option2: int) -> tp.Callable:
        @pytest.fixture
        def fixture() -> tp.Generator["SomeManagerOfSomething", None, None]:
           with SomeManagerOfSomething(...) as manager:
               yield manager
        return fixture

I notice that pytest.fixture returns a FixtureFunction type but that type is only available in the _pytest package. Is it possible to make it public or is there already something I can use that's more specific that lets me type the factory better?

i.e. so I can do something like

def make_fixture(cls) -> pytest.FixtureFunction["SomeManagerOfSomething"]:
