How to test stripe webhook using pytest-django

I have a docker-compose based development environment with

services:
    django:
    postgres:
    stripe:
        command: listen --forward-to http://django:8000/stripe/webhook

When the user uses stripe to make a payment, an event is forwarded by stripe to a webhook http://django:800/stripe/webhook, handled by the django instance.

When I use pytest to test the service, the following happens (as far as I understand):

1. django is still running with access to the regular database
2. A live_server with --ds=config.settings.test is created with access to the test database
3. When a payment is made during testing, stripe still forwards the request to django, which accesses the regular database, NOT the test database that is hooked to live_server, and the test payment would fail.

To fix this problem, we may

1. Fix stripe: Somehow configure stripe to --forward-to live_server.url/stripe/webhoo. This is what is supposed to happen but requires a different stripe cli instance to be created after live_server.url is determined.
2. Keep --forward-to to the regular django instance, but django (NOT live_server) will access the test database to complete the test. This may be easier but I am not sure how to configure django to access the test database.

Does anyone have any suggestions on how to do this properly?

Edit: A third option maybe running the tests on django directly without firing up a live_server, and using the normal database. The trouble is then how to direct pytest-django to NOT use the test database.

Begin with the docker-compose services and the pytest-django live_server setup described in the report; verify which process receives the Stripe webhook and which database it uses. Done means identifying a reproducible test configuration in which the webhook reaches the test environment and the payment completes, or documenting the project-specific decision needed.
