How to write test cases for Payment gateway process?

Payment Gateway Testing performs to verify the Payment Gateway process for online purchases and transactions by the users. To ensure the security, reliability, and performance of a payment gateway, it is important to test it by encrypting and securing the payment details between the user and the merchant.

A payment gateway system is a service that approves credit card/ debit card payments / electronic bank transfer payments. Payment gateways protect card details by encrypting sensitive information.

Types of Payment Gateway System

It is essential to have knowledge of payment gateways.

  • Hosted Payment Gateway Solutions:

    The hosted payment gateway system(PayPal or Worldpay) redirected customers from the e-commerce site during the payment process. The customer will return to the e-commerce site once the payment is made.

  • Shared Payment Gateway Solutions:

    While processing payment, a customer is directed to the payment page and stays on the e-commerce site.  eWay, Stripe is an example of a shared payment gateway, since it does not leave the e-commerce site while processing payment.

  • Check the payment gateway document for error codes
  • Familiarize yourself with the session and parameters passed through the application and payment gateway.
  • Evaluate the amount of related information passed through the query string, variable, or session.
  • The various settings of the payment gateway, such as currency format, affect what subscriber data is collected.

Examples of test cases for payment gateway testing.

The following are important test scenarios/cases to check the payment gateway:

  • After successful payment, make sure that all the parameters have been retrieved.
  • Determine what would happen if the payment gateway became unavailable during payment.
  • What happens if the payment session ends?
  • During the payment process, please verify the backend data.
  • Please investigate what happens if the payment process fails.
  • Check the security and error pages during the process.
  • Check that a confirmation page is shown to the user once a successful payment is done.
  • Please ensure that the transaction is processed immediately or that it is handed to your gateway account.

  • Please check if each of the payment options is selectable.
  • Check if each listed payment option works as expected.
  • Check if the payment gateway will accept the desired credit/debit option.
