CAPTCHA_TEST_MODE doesn't work with override_settings decorator

Django provides some decorators to modify settings on a per-test or per-test-class basis: django.test.override_settings and django.test.modify_settings (https://docs.djangoproject.com/en/dev/topics/testing/tools/#overriding-settings).

However, it seems django-simple-captcha reads and stores the project’s value of settings.CAPTCHA_TEST_MODE (and other settings) only the first time captcha.conf.settings is imported. Consequently, one must either specify CAPTCHA_TEST_MODE globally for all tests in a custom settings.py, or monkey-patch captcha.conf.settings…

It would make testing easier if settings were always read on-the-fly, rather than cached. Or, failing that, it would be good to at least provide notice in the config documentation (particularly for CAPTCHA_TEST_MODE) that they cannot be overridden by override_settings and modify_settings.

FTR neither does this work:

            try:
                settings.CAPTCHA_TEST_MODE = True

                response = self.client.post(
                    self.register_url,
                    {
                        "username": username,
                        "password1": "password",
                        "password2": "password",
                        "email": "[e-mail]",
                        "captcha_0": "PASSED",
                        "captcha_1": "PASSED",
                    },
                    follow=follow,
                )
            finally:
                settings.CAPTCHA_TEST_MODE = False

This is the only way how I managed to get it working:

            try:
                # https://github.com/mbi/django-simple-captcha/issues/84
                from captcha.conf import settings as captcha_settings
                captcha_settings.CAPTCHA_TEST_MODE = True

                response = self.client.post(
                    self.register_url,
                    {
                        "username": username,
                        "password1": "password",
                        "password2": "password",
                        "email": "[e-mail]",
                        "captcha_0": "PASSED",
                        "captcha_1": "PASSED",
                    },
                    follow=follow,
                )
            finally:
                captcha_settings.CAPTCHA_TEST_MODE = False

There is a solution for this. To make the CAPTCHA_TEST_MODE work, it needs to be set to True and the form will only be valid if you set captcha_0 and captcha_1. captcha_0 needs a hash (I copied one from my browser) and captcha_1 needs to contain “PASSED” (can be lower or uppercase) in string format.

for example: “captcha_0”: “8e10ebf60c5f23fd6e6a9959853730cd69062a15”, “captcha_1”: “PASSED”,
