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
