Often changes in the business side implies large changes in the corresponding code of the app to support it. Like changing business models from one-time purchase to subscription. Or that time when the business asked to provide that exclusive holiday app icon promotion for $1.99. All of these makes unit testing and integration testing of the app more challenging since in-app purchase code often interact heavily with the feature switches of corresponding products.

Won’t it be great if your in-app purchase code can keep working flawlessly as faced by business challenges?

How about having the ability to offer “exclusive limited-time availability” special features as if they were physical products?

How to offer fully-functional time-limited trials in Apple’s App Stores?

I’ve covered these and much more in my talk done for iOS Dev Scout, and you can watch it here.
