[Factory Boy] Create factory without model

[kenvontucky]

Description

Factory Boy requires a model to define a factory, however sometimes there's a need of taking advantage of the factory boy functionality without a model.

Requirements

Add an entry under Factory boy, where a solution such as the one below is presented.

from typing import NamedTuple
import factory


class TestUser(NamedTuple):
    id: int
    name: str


class TestUserFactory(factory.Factory):
    class Meta:
        model = TestUser

    id = factory.Sequence(lambda n: 1000 + n)
    name = factory.Faker('name')

Acceptance Criteria

Provide a complete example

tuf = TestUserFactory()

and

tuf = TestUserFactory(name="John O'Reilly")
