How to test renewable subscriptions (App Store)

Question

I\'m implementing auto renewable subscriptions in my app and I wonder if there is a way to simulate when a subscription period runs out and a new transaction is created.

Answer 1

Actually, I experience the renewal in the Sandbox to be very unpredictable. Sometimes it works as described, sometimes it works very differently, sometimes it doesn't work at all (saying that as a developer with an app in store that actually uses In-App-Purchases with autorenewable subscriptions, apparently successfully in production). Just at the moment I have a monthly subscription in the sandbox that has an original purchase date from 27 hours back and an expiry date of three hours back. I really wonder how you are supposed to test this if the responses are absurd like that.
