title: How to use test account on Google Play? GooglePlay always sees me as the purchaser
body: <p>I added a gmail account in the test input (in the Developer Console), I added my apk on my device, and I changed the account in <code>GooglePlay</code> app. But I always get the same error : "the purchaser cannot buy this item" as if I was using my developer account to test the purchase, which is not allowed. Does someone know how to test the app with the test user account?</p>
  
  <p>Thanks</p>
