We have successfully integrated in app purchase and are able to test it in sandbox mode. However, I cannot find anywhere in the docs where to test the records of all purchases made using sandbox account. Somewhere I can test the total amount earned at-least.
I have tried - App analytics, Sales and Trends, and Payments and Financial Reports section on appstoreconnect.apple.com
It seems there is no way to check sale/trends for test users. as the Test purchases are sandboxed.
