I am developing a simple billing library in the application. It works with static answers from google, but now I would like to test this library using real products in the application.
I created a test account and I'm trying to buy a product, but Google Play asks for my credit card. Is there a way to test billing in the application without using a real credit card (sandbox environment, fake credit card, etc.)?
I read here that the only way to check this out is to use a real credit card with a test account (so you don’t have to pay Google taxes), and once you bought the product, return it again, but it doesn’t seem very "friendly to the developers "way.
Thanks.
