Test Guide

1. Overview

Samsung In-App Purchase (IAP) supports your app IAP-integration and in-app item development testing of in-app item offering, purchase, and payment functionality before you submit your apps and in-app items (consumable, nonconsumable, and subscription) to validation testing and normal publication in Galaxy Store.

IAP testing of in-app item offerings (when your app gets and presents current item prices and details to app users) is the same as for normal publication. IAP testing of in-app item purchase and payment is the same as for normal publication except for subscription item testing changes, and some testers get items for free.

2. IAP Test Environment

3. IAP Testing

When creating tests of your app, in-app items, and Samsung IAP, the IAP tests are guidelines for test setup and initiating and verifying IAP functionality. You can test your app and in-app items with one or more IAP tests.

3.1 Preparation

For all IAP tests, prepare your testers, app, and in-app items:

  1. Ensure each tester has a valid credit card for payment.
    Side load tester and licensed beta tester credit cards are not billed for any item purchases.
    Non-licensed beta tester credit cards are billed for all item purchases.

    a. Set the IAP operating mode for the selected IAP test.
    mIapHelper.setOperationMode(HelperDefine.OperationMode.[IAP operating mode for the selected test])

    IapHelper.startPayment class parameter _showSuccessDialog is true or false

Registered item periods

  • Apply during production closed beta tests for non-licensed beta testers.

IAP test periods

  • Free trial and subscription periods end every 10 minutes on the hour (at hh:10, hh:20, hh:30, …). The first period after purchase or repurchase ends at the next 10-minute time. For example, if an item with a free trial is first purchased at 11:08, free trial ends at 11:10.
  • Apply during always successful side-load tests for all testers, and production closed beta tests for licensed beta testers.
