I completely removed tests for the StripeEventService as they were using a system I setup a while back that read JSON files of the Stripe event structure. I did not anticipate how frequently these structures would change with each API version and the cost of trying to update these specific JSON files to test a very static data retrieval service far outweigh the benefit.
