I have just developed and deployed an app to the Google Play Store.
As you can see, it is an alpha release. I have read that alpha releases can have their in-app purchases tested, without the tester having to incur a charge.
I have set up closed testing and assigned myself as a tester. I then download the app through the Play Store on my devise. I then attempt to test the in-app purchases, but I get the following:
As you can see, I cannot make the purchase as I don't have sufficient funds.
Question
How do you test in-app purchases so you are not charged?
Thank you
