Why this question?
I read many articles in "Google Play Developer Console" site (GPDC) but I don't understand how to completely test by myself an in-app billing requesting the Google Play server, before I submit it to testers:
I already got a licence key from Google Play. That points out that my apk file is correctly signed and that GPDC has already checked that.
My product is a one-time product. So, it would be useful, before testing it with the GPDC server, that I provide an item related to this "one-time product" to GPDC, isn't it? I don't read any info about that in the GPDC help.
Moreover, I have included the in-app billing library in my JavaFX code and I want to test it by myself (not by testers). So, the internal, alpha or production tests seem to be inapppropriate. In theses conditions, how to prepare an end-to-end test (I have already included the purchase mechanism). Then, how to test it by myself with GPDC server?
My development context is : JavaFX, Gluon Charm Down and its Gluonhq InAppBilling Service - Eclipse environment
Thanks in advance
Note: is it possible to use the GPDC "Instant app internal test" and include only my email/name in the tester list? In this case, can I test my app loaded in my phone and then make some requests to the GPDC server?
