Test card numbers

In order to create a test payment specify "testmode": true, when creating the payment in the API.

Example cards:

PAN	Action	Identifies as
`4000112401172221`	Authorize	Visa-Debit, Consumer, CA
`5500120801422221`	Authorize	Mastercard-Credit, Consumer, DK
`4242120802091112`	Fail on authorize	Visa-Credit, Consumer, DK

`5100116202241115`	Fail on refund	Mastercard-Debit, Consumer, CX

When testing card payments the PAN must validate the LUHN check^1. Using the following last 4 digits, you can
trigger an error for a given action on the payment.

PAN last 4	Fails on action
`1112`	Authorize
`1113`	Capture
`1114`	Cancel
`1115`	Refund

All PAN used that do not end with one of the 4 listed examples above, will be handled without error.

Testcards must conform to the following format:
