Not a workflow solution, however if it’s purely for testing with Stripe you should be able to use test data / test mode with Stripe (which I’m sure you’re aware of if you’ve got Stripe set up). Then on payment it’s just the 4242 card.

All user acceptance testing that we do across our apps is with Stripes test mode on, then to confirm the payments and platform fees are working we do payments under $10 on live.
