When submitting your app, include clear instructions for testing during the review process.
Providing usage instructions helps us deliver precise feedback if issues arise during testing. If you have an app that offers a lot of functionality, then you should consider including a link to a video walkthrough of your app. This helps reviewers fully understand your app’s capabilities.
If your app connects to other services, then you must include test accounts. For example, if your app requires account access to a marketplace, then you must include credentials for a test account on that marketplace. Failure to include required test account credentials will result in the rejection of your app submission.
