In my iOS app, I successfully process promoted in-app purchases. During development, I could test the flow by navigating to an itms-services URL, in accordance with this guide: https://developer.apple.com/documentation/storekit/in-app_purchase/testing_promoted_in-app_purchases.
But how can promoted in-app purchases be tested for tvOS? There is no web browser in which to click such a URL, and the testing document doesn't mention anything about testing for tvOS. According to its documentation, paymentQueue(_:shouldAddStorePayment:for:), the method used for handling a promoted in-app purchase, should be compatible with tvOS, and I currently have that implemented, but just no way of testing it before release.
