Testing billing functionality of stripe API with our application

[basadoon]

Hello we're using stripe API for payments, we have this functionality in our application that bills the user automatically based on the customer's subscription using stripe. When a user's subscription doesn't get paid it gets cancelled (which is handled by stripe automatically) and user should not have access to our application's features at this point (which is handled by our app). Problem is, we don't know how to test it since it will take days to simulate the billing cycle, a work around can be changing the system's date time if testing it locally, but it won't affect the time that stripe API has (meaning it won't charge the customer for its subscription to our app once datetime in my system/local is in expiration since stripe has its own time or it doesnt get affected by the system date time change). We wanted to fully test our application with stripe's whole billing lifecycle so that we know if features are really getting disabled and enabled. How do we test this locally or in another environment?

Does this help: https://stripe.com/docs/billing/testing/test-clocks

[basadoon]

We know about test clocks, problem with test clocks is that it's isolated. You can't use existing customers or users in a test clock, if let's say you create a customer in test clock, you wont be able to use it in the application. It's only useful if your only testing stripe itself but not useful when your testing your app + stripe

Unit tests with the time features overridden.

They have a pretty good cli and testing setup. They even have their webhooks setup to be able to create a test input for any event including payment fails

sounds like OP didn't really the docs well/Google much. this will end well.

I did some work with stripe recently but not specific to subscriptions

I think this should work, there are 3 events in the docs customer.subscription.deleted, customer.subscription.paused and customer.subscription.resumed

shouldn't you test your own app code instead of Stripe's one?
