Authorize.net credit card number ?

Authorize.net credit card number ?

Hi,
I just purchased authorize.net plugin.
Unfortunately it goes without any manual or description.

Currently I try to use it in test mode, but it gives error:
(TESTMODE) Credit card number is required.

But there is no place to put this number

Any help is appreciated.
