The present and future of business lie in selling products and services online. This is what makes online payments an indispensable part of sustainable growth. Irrespective of the type of business you run, you need to integrate a suitable payment gateway to start accepting payments online.
With the current pace of growth, the Indian payment gateway market is expected to reach US$ 1.71 billion mark. While there are many payment gateway providers available in India, selecting the right payment gateway is of paramount importance.
Payment gateways are also responsible to safeguard consumers’ card details with the help of tokenisation. Hence, it is important to ensure that the integrated payment gateway is working as expected with the help of payment gateway testing.
Let’s dig deeper into various facets to know how to test payment gateway functionality.
What is payment gateway testing?
Payment gateway testing is the process of evaluating various features of a payment gateway before putting it into use to start accepting payments online. The primary purpose of payment gateway testing is to ensure that the chosen payment gateway is secure, reliable, and delivers uninterrupted performance.
At the merchant side, the payment gateway test cases ensure that the entire process from payment debit at the customer’s end to settlements/refunds work seamlessly. On the customer side, the testing process keeps a check on the ease of use with just a couple of clicks/taps and payment security.

Need for payment gateway testing
It would be easy to understand the need for payment gateway testing with an analogy –
Let’s assume you own a local brick-and-mortar shop selling cakes and only accept payments offline. Every time a customer buys cakes from you, you accept the payment in cash or via POS machines to swipe the cards. You get the confirmation that you have received payment while the same amount gets deducted from the customer’s bank account.
Expand the same cake shop to accept orders online, and you will need to ensure whether the underlying payment gateway is working well to settle the payments into your bank account timely as expected.
Hence, payment gateway testing allows the merchants to evaluate the selected payment gateway based on its features, benefits, and suitability for their businesses.

There are five main types of payment gateway testing processes that assess the payment gateway from various angles before you can put it into use. These include:
