When it comes to handling credit and debit cards, thorough testing is crucial to ensure the security and reliability of transactions. This guide outlines the key card test cases you need to consider.

1. Card Validation

Before processing any transaction, it's important to validate the card details. This includes checking the card number, expiration date, and CVV code.

After authorization, the transaction is processed. This includes updating the cardholder's account balance and recording the transaction details.

4. Fraud Detection

Fraud detection is a critical aspect of card testing. It involves analyzing transaction patterns and identifying any suspicious activities that may indicate fraudulent intent.

5. Error Handling

Proper error handling is essential to provide a seamless user experience. This includes handling declined transactions, expired cards, and other common issues.
