Here's an interesting design question I ran into recently. Some details have been changed for client confidentiality reasons.

You operate a car rental aggregation service called ParkingGarage. Individual rental agencies use your API to tell you about excess inventory, which they then give to you to sell.
ParkingGarage doesn't actually sell the inventory, however. Instead, it acts as a sort of rental-car exchange and makes the inventory available to third-party services who would like to book reservations. ParkingGarage charges a 5% fee on each reservation as a commission and gives the balance to the rental agency that posted the inventory.
Word of your service spreads and it gets very popular. Three affiliates AppleAudis, BananaBeetles, and CoconutCars sign up to be your first sellers. Each affiliate is a distinct, separate service that derives its inventory from a variety of sources, of which ParkingGarage is only one. They love your API, and they're selling cars like hotcakes.

	(2010-10-14 16:18:21) jsquared (irc.freenode.net): jherdman: Entire scenarios. I have a test which makes a request to an external system which then returns a confirmation number. Then that confirmation number is used by other scenarios.
	(2010-10-14 16:18:41) jherdman: i'd stub that shit. you don't want external services being involved with your stories
	(2010-10-14 16:19:47) jherdman: that way you also don't need to do anything weird to save a value between scenarios ;)

	(2010-10-14 16:21:33) jsquared (irc.freenode.net): jherdman: Well, this is a bit of an unusual use for Cucumber. We're getting certified against the external system by sending a series of messages to it and testing that the responses match what is expected.
