Unable to add test card for apple pay testing

Hi I have just got this answer from support

It’s not possible to add a test credit card number (even Braintree’s test cards) into Apple’s Passbook. So any credit card you wanted to add into Passbook even for testing purposes would need to be real.

updating it so that user should not be confused when they work with apple pay.

Visit the developer page here. and scroll down there are some testing credit card list available.

You need to setup a sandbox test account and then add cards to wallet using the data provided on apples website. You cannot just use that data when you signin into your device using regular Apple Id.
