Google Checkout HTML API - Credit Card Test Cases

Credit Card Test Cases Overview

Google Checkout provides a testing feature for the sandbox environment that enables you to submit an order that will return a specific type of Address Verification System (AVS) response or credit verification value. The feature also lets you specify that Google Checkout should send an order state change notification indicating that the credit card for a sandbox order was either authorized or rejected.

To use this feature, you will need to create a different test instrument for each test case that you want to verify. The sandbox server will use the billing information associated with an order to determine the correct AVS value, credit verification value or credit card authorization status for the order.

To create these different test billing instruments, log in to your sandbox customer account and click the Edit payment methods link on the left side of the page. The Payment Methods screen displays a form to add a new credit card to your account. This form is shown in the image below.

Using this form, add a credit card for each test that you would like to complete. The table below identifies the different tests that are available and specifies the appropriate values to use in the form. Each test instructs you to enter particular values for the billing credit card number, the billing contact name and the billing address. In addition, several tests require a specific CVC code for the credit card. Unless otherwise noted in the Additional Instructions field, enter any four-digit CVC code for American Express, and enter any three-digit CVC code for Discover, MasterCard or Visa. After you click the Save button to store a card, the page will refresh and you can use the form to add an additional card.

Please note the following points regarding the billing information for these test cases:

• All of the credit card numbers below are randomly generated numbers. In addition, none of the credit card numbers has the same last four digits as any other credit card number. This ensures that when you select a credit card to complete an order, you can easily associate a test credit card with a particular test.

• Each test instructs you to enter a value for the billing contact's name and address. However, the name and address values for any given test are the same. The test case is actually triggered only by the address field. However, we advise you to also enter the same value so that if we display the billing contact name in the UI, you can easily associate that name with a particular test case. So, for each test case, the Address field value is required, and the Name field value is recommended for your convenience.

After creating your billing instruments, follow the steps below to verify these test cases:

1. Post a shopping cart to the Google Checkout sandbox server.

2. Select the credit card you would like to use to complete the purchase. Note that the order confirmation screen will only display the last four numbers of each credit card number. Please see the Credit Card List for Test Cases for a printer-friendly list of credit card numbers organized by card type (AMEX, Discover, etc.) and by test case.

3. Click the Place your order now button.

4. Click the Sign out link in the upper-right corner of the page.

5. Log in to your sandbox seller account. (This should be the test merchant to which you submitted the order.)

6. In the order inbox, click on the order that you just placed. Confirm that the Buyer credit verification window shows the appropriate AVS or CVV response for your test case. If you are testing to see whether a credit card is authorized or declined, the Order history window should reflect the correct information.

7. If you have implemented the Notification API, verify that you receive the appropriate notification for the test:

   • For tests 1 through 9, you should receive a risk information notification with the appropriate avs-response or cvn-response value for that test.
   • For test 10, you should receive an order state change notification indicating that the order's financial status has updated to CHARGEABLE.

Test Case for Failed Credit Card Authorization

The test case for receiving a failed credit card authorization uses a slightly different process. The process is different because if Google receives a failed authorization, Google will not let a customer use the same credit card until the card information is updated. As such, for this test case, you need to add the credit card while completing the purchase and then delete the card after it has received a failed authorization. The following steps explain how to test failed credit card authorizations:

1. Post a shopping cart to the Google Checkout sandbox server.

2. Enter a new credit card to complete the purchase. Please use one of the following credit card numbers:

   • American Express: 340682458348749
   • Discover: 6011191466819647
   • MasterCard: 5116381817387388
   • Visa: 4116196783374209

   Enter AUTH+DECLINE as the value of the Name field and the first line of the Address field.

3. After adding the new credit card, click the Place your order now button.

4. Click the Sign out link in the upper-right corner of the page.

5. Log in to your sandbox seller account. (This should be the test merchant to which you submitted the order.)

6. In the order inbox, click on the order that you just placed. Confirm that the Order history indicates that the authorization was declined.

7. If you have implemented the Notification API, verify that you receive an order state change notification indicating that the order's financial status has updated to PAYMENT_DECLINED.

8. After reviewing the test case, log in to the customer account that you used for the test. Delete the credit card that received the failed credit card authorization.
