Testing procedure:

• Verify that users can initiate a payment transaction.
• Confirm that the user can specify the recipient's details, payment amount, and payment purpose.
• Ensure that the payment system validates the recipient's details, including account number, IBAN, or EDRPOU, depending on the payment method.
• Verify that the system checks for any errors or invalid entries before processing the payment.
• Confirm that the user receives a payment confirmation before the transaction is processed.
• Verify that the confirmation includes details such as payment amount, recipient, and a transaction reference number.
• Verify that users can check the status of their payment transactions (e.g., pending, completed, failed).
• Confirm that users receive real-time updates on the payment status.
• Ensure that a history of payment transactions is available for users to review.
• Verify that payment history includes details such as date, recipient, amount, and status.
• Test scenarios where payments may fail (e.g., insufficient funds, incorrect recipient details) and confirm that users are provided with informative error messages.
• Confirm that the payment system uses secure and encrypted connections for all transactions.
• Verify that sensitive payment information (e.g., credit card details) is stored securely, following industry standards.
• If applicable for international payments, ensure that the payment system correctly handles currency conversions and displays accurate exchange rates.
• Confirm that users receive digital receipts or confirmation emails after making a payment.
• Verify that receipts include all transaction details and a unique reference number.
