in-app purchase: skudetails always empty

[rajeevsd]

i'm integrating in-app purchase billing library in my app. Does in-app purchases work only on published apps?. My app is in pending publishing state. In coding part skuDetailsResponse always returing empty array. Billing client connection response code is 0.
If it works only for published apps and test users, then how can i code and debug the functionalities?
