How to verify in Production functionality, using a test Credit Card?

Hello,

We are promoting QA tested code to Production environment, and this will start using Moneris Production environment instead of QA environment.

How can we test this (on Moneris Production environment) before more actual users start to use the site?

Is there a Production CC number we can have to do test, or we have to use our personal CC numbers to verify that everything works on Production environment?

We would also like to use this Production CC number for automating deployment-validation testing if Production, if available.

Thanks.
