Credit Card Testing

Credit Card Testing

Credit card related testing is vast field and sometimes it requires more information on it. I have try to write some tips for testing Credit card Application. There may be chances for more scenarios, but I just tried my best.

First of all check with your payment gateway that how many types of cards they support, like Master card, Visa card, American Express, Discover etc.
Then each and every card has specific number of digits as card number. For example say, Discover should have 17 digits only.
Also each card will have an expiry date.
Test the boundary conditions for credit card by giving more than 17 digits and less than 17 digits.
Invalid credit card number.
Invalid Expiry date etc
Network response
Buffer page between application page and payment gateway page
URL information with card and amount details

Dummy Credit Card Numbers for Testing

Here is a list of dummy credit card number that can be used while testing your applications involving credit card transactions:

Visa: 4111-1111-1111-1111
MasterCard: 5431-1111-1111-1111
Amex: 341-1111-1111-1111
Discover: 6011-6011-6011-6611

Credit Card Prefix Numbers:

Visa: 13 or 16 numbers starting with 4
MasterCard: 16 numbers starting with 5

While testing, use only the credit card numbers listed here. Other numbers produce an error.Expiration Date must be a valid date in the future (use the mmyy format).
