Valid payment method:
- Test with a valid credit card or other payment method to ensure successful transaction processing.
Invalid payment method: - Test with an invalid or expired credit card to ensure appropriate error handling and error messages are displayed.
Card authorization:
- Test if the payment gateway authorizes the card properly before processing the payment.
Verify that the appropriate authorization holds or pre-authorization occurs.
Payment processing timeout: - Simulate a slow payment processing response to check if the system handles timeouts gracefully.
Verify that users receive proper error messages and are not charged multiple times if they retry the payment.
Payment declined:
- Test with a valid payment method but intentionally decline the transaction to verify that the system handles declined payments correctly.
Check if users are provided with clear error messages and prompted to try an alternative payment method.
Payment confirmation: - After a successful payment, verify that users receive a confirmation message and/or email with the transaction details.
Test the accuracy of the information displayed in the confirmation message or email.
Payment security:
- Verify that the payment process is secure by ensuring that sensitive information, such as credit card details, is transmitted securely using encryption (HTTPS).
Confirm that no sensitive information is stored on the server or in browser cookies after the payment is completed.
Payment currency: - Test the website’s ability to handle different currencies and ensure that payments are processed correctly for each currency.
Payment gateway integration:
- Test the integration between the website and the payment gateway to ensure that data is properly transmitted and received.
Check if any custom fields or additional data required by the payment gateway are correctly handled.
Payment refund or cancellation: - Test the refund or cancellation process for a payment and verify that it is executed correctly.
Ensure that the appropriate messages are displayed to users and any associated actions (e.g., inventory management) are handled properly.
Concurrent payments:
- Simulate multiple users making payments simultaneously to ensure that the system can handle concurrent transactions without errors or data corruption.
Cross-browser and cross-device testing: - Test payment methods on different browsers (e.g., Chrome, Firefox, Safari) and various devices (desktop, mobile, tablets) to ensure consistent functionality and user experience across platforms.
