Test your introductory pricing in a variety of user scenarios.
To test introductory offers, verify that users see the same subscription and introductory offer prices in your app as they do in the App Store. As part of your test, make sure your app presents introductory offers only to users that are eligible for the offer.
To test introductory offers:
Configure test accounts, as described in Create a sandbox tester account. Create a variety of accounts that are eligible or ineligible for offers.
Initiate in-app purchases from within the app for each test user.
Verify that the user experience and pricing information dynamically represent the accurate price of your subscription.
