How do I write a type hint for a test Response?

[juliancoffee]

Hi, first of all, thank you for this awesome project, but I have some questions.

I see there's _MonkeyPatchedWSGIResponse, but I've no idea how I'm supposed to use it

I tried

from django_stubs.test.client import _MonkeyPatchedWSGIResponse

but no luck, mypy warns of [import-not-found] for django_stubs.test.client, while the example with TypedModel from README works, so my configuration seems to be ok.

I suppose it is some kind of private type I'm not supposed to use, but what should I use instead?

that's how I'm using it, if that'll help 👀

class FormTestCase(TestCase):
    # I know that assertFormError exists, but it requires a fieldname, and that's
    # a weird limitation imo, so here's my version instead.
    def assertFormContainsErrorCode(
        self, response, error_code: str
    ):
        """Check that form errors contain the error with error_code"""
        form: Form = response.context["form"]
        errors = form.errors.get_json_data()

        # flatmap and find the code for each message for each field
        # NOTE: eagerly evaluate the iterable for better error messages, but
        # it'd work without it as well
        error_codes = list(
            map(lambda e: e["code"], chain.from_iterable(errors.values()))
        )

        self.assertIn(error_code, error_codes)
