Android in-app billing error with android.test.purchased item

Question

I'm trying to test my in app purchase flow with the fake item android.test.purchased, from android documentation. I'm not able to test this flow, just when I launch it, I get this error: "The item you requested is not available for purchase". I have the permission in my manifest and I don't understand why I get this error with the fake item android.test.purchased.
