I involved in a project where we validated the credit cards like...Master Card, Visa, American Express and Discover. What we do while testing this is.....Each and every type of card will have a specific number of digits as Card Number. For example say, Discover should have 17 digits only. Also each card will have an expiry date. With these validations in mind, we will write test cases like 1. Test the boundary conditions for credit card by giving more than 17 digits and less than 17 digits. 2. Invalid credit card number. 3. Invalid Expiry date etc
