I am almost ready to go live with my shopping cart with authorize.net credit card processing. However, I have a question.

Right now my authorize.net is configured as testing mode. I found that it only validates the credit card number and expiration month/year. It doesn't do AVS or CVV2. It doesn't even check if I entered the correct name.

Is that normal for the testing mode?

Try using the error card number: 4222222222222. The dollar value of the transaction will become the x_response_reason_code. I think a 65 is an invalid cvv2 number. So if you use that code and an x_amount of 65 you'll get the cvv2 code error to test your validation code against.

It is all documented in the SIM manual.
