What is CVV and Why Test It?

CVV, or Card Verification Value, is a three-digit number found on the back of credit and debit cards. It's used to verify the cardholder's identity during transactions. Testing CVV on a User Interface (UI) ensures that the system correctly validates this number for secure transactions.
