How can this be tested?

Nothing should break

FWIW, I opened an issue in the upstream CyberSource repo for the SyntaxWarning issue we discussed: CyberSource/cybersource-rest-client-python#143

I also figured out a workaround. You can use the warnings module to filter out SyntaxWarning when importing the payment_gateway library (or this can be migrated up to ol-django - that might be easier since less imports to deal with). This would obvs be temporary but it would make it work for the short term:

import warnings

with warnings.catch_warnings():
	warnings.filterwarnings("ignore", category=SyntaxWarning)
	from CyberSource import ApiClient, OrdersApi

(this will need updates for the actual imports and such)

I tested this in a test app I did up (see the issue) and this was sufficient to make pytest stop failing.

Need some help from @rhysyngsun on a hypothesis test error

[rhysyngsun]

I poked at this for about an hour. An upgrade to celery-redbeat is needed too because I can't build the docker container without doing that first. It's probably a good day or so to dig into what changed with hypothesis as it's several major version upgrades all at once.

I'd suggest instead holding off on this until we finish switching over to keycloak at which point we'll just be removing the failing code here anyway.
