DictFactory does not override _setup_next_sequence

[martsime]

Description

Overriding _setup_next_sequence does not work when subclassing DictFactory, but I get it to work for other factories subclassing DjangoModelFactory.

Model / Factory code

import factory


class TestDictFactory(factory.DictFactory):
    @classmethod
    def _setup_next_sequence(cls) -> int:
        return 10

    number = factory.Sequence(lambda n: n)

Test case

A simple test case where the sequence should start from 10

def test_dict_factory():
    test = TestDictFactory()
    assert test["number"] == 10

Output
