I am currently developing a sales channel app and I would like to know how we could go about testing our app. I would like to test the checkout api and payments using test data including test stripe tokens and others before rolling out into production. I have currently setup a test store and I am wondering if it is possible to use test stripe tokens with this. If not, how can I isolate my testing such that it would not affect production app (i.e. using stripe live keys).
