Payment systems have become an integral part of a variety of websites and applications. E-commerce is the first thing that comes to mind, but it is not the only one. Just think about services and applications you use regularly. Food delivery, streaming services, e-learning platforms, taxi apps – the majority of them have in-built payment functionality.
Whether we are talking about a fully functioning payment system or a payment gateway, it requires testing before the product goes live. In this article, we decided to cover the basics – the importance and particularities of this testing type and the way a functional testing company approaches it.
It would be helpful for stakeholders who want to know more about quality assurance for their product and beginner QA specialists in a manual QA testing services company.
Functional testing aims to verify that the real behavior of the implemented features matches the requirements and specifications described in the project documentation.
In other words, QA specialists check the functionality to make sure that a buyer can pay for a product or service, and a provider can receive this money in full amount. That’s the basic requirement of the correctly functioning payment gateways.
It is also necessary to verify that the payment form accepts only active cards, completes the transaction only if the costs are sufficient, etc. Without clarifying these and related things, there is no sense in enabling a purchasing feature on a website. In payment systems testing, when a QA team is to check a payment solution as a full-fledged piece of software, not just an integrated part, the scope of tasks increases.
Each type of payment solution will require a different approach. A common thing is a need for flawless functionality. Without the features functioning correctly, a payment solution as such is of no use. If the core features work, but there are severe defects, it will result in inconveniences for clients.
The range of consequences can also differ – from a minor decrease in customer satisfaction to considerable financial implications. Put it another way, there is a direct correlation between the quality of a payment system and the business performance of the provider and/or service using it.
Exploratory and Functional Testing for the Payment System
The term ‘payment systems testing’ can refer to testing a niche product or payment as a part of some other service. The thing is, testing of a payment solution can take place on either side. To be more specific, a provider of a payment solution (PayPal, a payment aggregator, etc.) should ensure that the functionality they offer works and can integrate with other platforms. Meanwhile, we need to examine this integration when testing a particular e-commerce platform or another website.
The software testing process starts with planning and preparation. The team needs to create a Test Strategy, write test cases or checklists (if it is not exploratory or ad hoc testing), and set up the tech stack.
As a rule, a software testing company chooses specialists with relevant background and domain expertise to work with payment solutions. Thus, the team will be familiar with the terminology and the required setup. We’ll list the core terms and needs below for those learning the basics or needing to refresh their memory.
The next question is ‘What exactly to check?’ We’ve explained how to write test cases in detail in our previous blog post. You can look up the structure and tips there. For now, we’ll list some of the main cases QA specialists apply during payment systems testing.
The audience expected to use payment systems is vast. Therefore, it is essential to work on empathic design – human-centered and based on the deep understanding of the realities of the future users. It is one of the reasons why payment functionality on the majority of websites looks similar.
Creating such a design is a task for a different team. QA engineers are the ones to check the result and verify that graphical elements look and work as planned. Below, you can see some of the essential things to check during UI testing services:
Functional testing in the payment domain is essential. Without a careful inspection of such a complicated solution, a company is likely to end up with a product that sabotages their business performance and affects brand image. Functional testing always goes hand in hand with UI testing.
In this article, we explained the importance of these testing types and the peculiarities of the QA process in general. Many aspects of testing will differ depending on the type of payment software and its features.
