If you have ever engaged in an online transaction, you know that you are directed to a safe and secure payment gateway. In contrast to financial transactions offline where confirming the payment is far easier, online payment service requires a superior level of protection. Doing test cases for payment gateway thus becomes important to ensure that the customer data is being protected at all times and is not vulnerable to any third party. Before we jump into the testing required for payment gateways, let us understand why testing of payment gateways is important.
Why is Testing of Payment Gateways Required?
In contrast to an open transaction where you either pay in cash or through your card, an online transaction requires confirmation that it is you who is consenting for the payment. In the offline mode, the Point of Sale testing machine works to check if the payment is approved or not. This approval feature also needs to be effectively used in the case of online payments.
An important aspect of test cases for payment gateway involves whether or not the customer is getting good service. The shift from the merchant site to the payment gateway should be as simple as possible without taking minutes. Whether the payment is approved or declined should be shown on the screen within seconds so that the customer can take the required action. The seamless working of a payment gateway is essential for the merchant to adequately serve their clients and provide corresponding services.
What are the Different Kinds of Testing for Payment Gateways?
There are several test cases for a payment gateway that need to be undertaken based on application and client requirements. The testing which would be required includes:
● Functional Testing
Functional testing is used for checking the compatibility of the payment gateway with the application of the merchant. The functional testing works to see if the gateway is functional or not. This is mostly seen for new gateways because they are still in the process of establishing themselves.
● Integration Testing
Integration testing is related to whether or not the application or website is integrating well with a particular payment gateway or not. Through Integration Testing, for any tester, the test cases for payment gateway include checking the seamless transaction flow.
● Performance Testing
After the general functionality and integration of the gateway and application/website match, the performance testing checks whether or not the gateway can take a load of multiple users accessing the portal at once.
● Security Testing
It is essential to check whether or not the transaction is secure from any third party wanting to access valuable customer data. The credit number, passwords, and CVV needs to be protected through the interface and firewall.
How to Effectively Test Functioning of Payment Gateways?
Here are some tips to help you with efficient testing:
● Be thorough with your research
You would ideally require a free sandbox environment available for the testing of the payment gateway. A free sandbox allows for more flexibility when it comes to customization as well as testing.
● End-to-end testing
This is specifically recommended for transactions. This will help discover bugs and security breaches that need to be fixed. The bugs could be related to the functioning of the integration which will only be fixed if the transaction is tested end to end.
Understanding the details of test cases for payment gateway is essential for making sure that the page for transactions is easy for the client to access. It is also essential to make sure the website and application are easy for the merchant to manage.
