Payment Gateway Testing:
Payment Gateway Testing is the testing of a Payment Gateway in a system for online purchases and transactions by the users. The purpose of payment gateway testing is to ensure the security, reliability, and performance of a payment gateway by encrypting and securing the payment details between user and merchant while providing a smooth payment experience.
A payment gateway system is an e-commerce application service that approves credit card payments for online purchases. Payment gateways safeguard credit card details by encrypting sensitive information like credit card numbers, account holder details, and so on. This information is passed safely between the customer and the merchant and vice versa.
Modern payment gateways also securely approve payments via debit cards, electronic bank transfers, cash cards, reward points, etc.
Types of Payment Gateway System:
Payment Gateway Knowledge is Important
- Hosted Payment Gateway: Hosted payment gateway system directs customers away from an e-commerce site to a gateway link during the payment process. Once the payment is done, it will bring a customer back to an e-commerce site.
For such type of payment you don’t need a merchant id, an example of a hosted payment gateway are PayPal, Noche, and WorldPay. - Shared Payment Gateway: In a shared payment gateway, while processing payment customer is directed to the payment page and stays on the e-commerce site.
Once the payment detail is filled in, the payment process proceeds. Since it does not leave the e-commerce site while processing payment, this mode is easy and preferable, an example of a shared payment gateway is eWay, Stripe.
Testing Types for Payment Domain:
Testing for Payment Gateway should include
- Functional Testing: It is the act of testing the base functionality of the payment gateway. It is to verify whether the application behaves in the same way as it is supposed to like handling orders, calculation, the addition of VAT as per the country, etc.
- Integration: Test integration with your credit card service.
- Performance: Identify various performance metrics like the highest possible number of users coming through gateways during a specific day and converting them to concurrent users
- Security: You need to perform a deep security pass for Payment Gateway.
How to test the Payment Gateway Complete Checklist:
Before you begin testing –
- Collect accurate test data for the dummy credit card number for the maestro, visa, master, etc.
- Collect payment gateway information like Google Wallet, Paypal, or else
- Collect payment gateway documents with error codes
- Understand the session and parameters passed through the application and payment gateway
- Understand and test the amount of related information passed through query string or variable or session
- Along with the payment gateway language check the language of the application
- Under the various payment gateway settings like currency format, subscriber data is collected.
Example Test Cases for Payment Gateway Testing:
Following are important Test Scenarios/Cases to check Payment Gateway
- During the payment process try to change the payment gateway language
- After successful payment, test all the necessary components, whether it is retrieved or not
- Check what happens if the payment gateway stops responding during the payment
- During the payment process check what happens if the session ends
- During the payment process check what happens in the backend
- Check what happens if the payment process fails
- Check the Database entries whether they store credit card details or not
- During the payment process check the error pages and security pages
- Check the settings of the pop-up blocker, and see what happens if a pop-up blocker is on and off
- Between payment gateway and application check buffer pages
- Check on successful payment, a success code is sent to the application and a confirmation page is shown to the user
- Verify whether the transaction processes immediately or the processing is handed to your bank
- After a successful transaction check if the payment gateway returns to your application
- Check all formats and messages when the successful payment process
- Unless you don’t have an authorization receipt from the payment gateway, goods should not be shipped
- Inform the owner of any transaction processed through e-mail. Encrypt the content of the mail
- Check the amount format with the currency format
- Check if each of the payment options is selectable
- Check if each listed payment option opens the respective payment option according to the specification
- Verify whether the payment gateway defaults to the desired debit/credit card option
- Verify the default option for debit card shows the card selection drop-down menu
Things to consider before Buying the Gateway Package:
- If you have bought a shopping cart package, find out about its compatibility
- If a shopping gateway package is due, ask the payment gateway provider for a list of supported applications
- The gateway must offer Address Verification System Protection
- Find out the types of transaction protection being offered
- Check what types of debit or credit cards are accepted by your chosen payment gateway
- Check the transaction fees levied by a payment gateway
- Check whether the gateways collect the payment right on the form or directly to another page to complete the purchase
Conclusion:
A payment gateway must provide a seamless experience in the realm of online transactions, for which it must be tested. The main objective of the testing process is to ensure the security of a transaction by encrypting the details of the customer and the merchant.
