What is Payment Gateway Testing? Test Cases Example

With a growing consumer base, e-commerce platforms need to provide user-friendly and secure payment gateways that can handle high loads without causing any downtime. Before implementing online payment, businesses need to ensure that their eCommerce platforms are compatible with the gateway and offer an exceptional user experience.

The payment gateway sends the information for the transaction channel to a merchant bank. It then checks the response from the bank. Modern payment gateways can also securely approve payments via debit cards and electronic bank transfers, cash cards, or reward points.

What is Payment Gateway Testing?

A payment gateway allows service providers to accept online payments. The gateway is an interface that acts as an intermediary for merchants and acquiring banks. Payment gateways are typically used to process payments using credit cards. But modern applications can handle electronic transfers and debit cards.

Merchant side payment gateway testing cases ensure that payment debits at the customer’s end are processed seamlessly and that settlements/refunds are handled smoothly. The customer side is subject to the same testing, which focuses on ease of use and payment security.

Payment Gateway Test Cases

A gateway that accepts accurate payments should be tested before being used. It is done by testing engineers who use a variety of test scenarios and case studies. A test scenario can include any feature or functionality you wish to test.

Let’s look at some test cases you should use to validate a payment gateway.

• Verify that all required fields are correct on the payment page. You should not proceed with payment processing if you don’t have any mandatory information.

• You can test the integrated payment gateway using various payment sources, including debit/credit cards and net banking.

• After each successful transaction, look out for the message on the screen.

• To confirm your payment status, make sure you check the notification URL, return URL, and status call.

• After every successful transaction, check if the payment gateway redirects to the app/website.

• Take a look at each transaction’s database entry. It should be in the correct format. In the event of an unsuccessful transaction, test the payment flow.

• Check the currency that the gateway reflects according to the user’s country.

• In the event of cancellation, check for the processing time to refund the order amount. You can check the processing time to credit the customer’s account with refunds.

• If the gateway does not function as expected, check the payment result after the session is over.

• Ensure that you are looking for security and error pages during the payment process. For successful transactions, make sure to review all messages sent to the merchant and user.
