Overview

Description

This credit card object can be used as a stand alone object. It acts just like an ActiveRecord object but doesn’t support the .save method as its not backed by a database.

For testing purposes, use the ‘bogus’ credit card type. This card skips the vast majority of validations. This allows you to focus on your core concerns until you’re ready to be more concerned with the details of particular creditcards or your gateway.

Testing With CreditCard

Often when testing we don’t care about the particulars of a given card type. When using the ‘test’ mode in your Gateway, there are six different valid card numbers: 1, 2, 3, ‘success’, ‘fail’, and ‘error’.

– For details, see CreditCardMethods#valid_number? ++

Example Usage

cc = CreditCard.new(
  :first_name => 'Steve', 
  :last_name  => 'Smith', 
  :month      => '9', 
  :year       => '2010', 
  :type       => 'visa', 
  :number     => '4242424242424242'
)

cc.valid? # => true
cc.display_number # => XXXX-XXXX-XXXX-4242
