How to test non-consumable Android purchases?

Question

Android

An app that has a non-consumable purchase (disable ads).
Question to the developers: how do you test it when you release updates?
The option (buy) - (copy the payment code) - (send to the publisher) - (he will cancel) - (reinstall the game) - (clean com.android.vending) works, or creating a new account each time and adding it to the list of testers - also works, but I won’t write it all as ...
The option suggests itself to create a cheat. I turn it on: then the purchase is made as a consumable, or when the game is reinstalled, sending a Google Play Billing request for automatic restoration is blocked, or receiving a response is blocked, or such a purchase is simply consumed immediately through consumeAsync.
How the hell do you do it?
