Banking applications are one of the critical customer channels for financial organizations, and app users expect their online banking services to be just as smooth and easy as their in-person banking experiences. As customers use banking services around the clock, it has become imperative for BFSI companies to offer a seamless customer experience. Financial organizations rely on their QA teams to enhance and update their banking services to retain customers. The IT spending in the BFSI sector is expected to grow steadily and reach USD 715 billion in 2025. This shows the increasing interest of banking enterprises in IT solutions, like end-to-end testing and test automation, to improve the performance of their apps and banking solutions.

This article highlights the importance of end-to-end testing in the BFSI industry, and the challenges faced by banking companies while implementing end-to-end testing.

Role of End-to-End Testing in the Development of Banking Solutions

Since the BFSI industry is undergoing a lot of changes due to digital transformation and technological advancements, banking organizations have a significant dependence on technology-enabled products to ensure a great customer experience. To deliver safe and secure transactions, companies are focusing on effective testing methods for all activities performed by banking software/apps. End-to-end testing is one of the software testing methods in financial services used to run banking apps smoothly without any errors. With end-to-end testing, banking enterprises can monitor and test all operations involved in an application. 

Some of the significant factors that make end-to-end testing necessary for banking solutions include:

1. Regulation and Business Requirements

In order to operate efficiently in the banking industry, companies need to maintain business transparency and follow certain rules set by regulators. End-to-end testing can help banking companies ensure that all banking solutions abide by regulatory compliance terms and conditions.

2. Digital Transformation

With the emergence of smartphones, tablets, and IoT-based devices, the financial industry is witnessing a massive change in the digitalization of banking and digital payment methods. With the introduction of automation in financial services, end-to-end monitoring and testing are required to ensure that paperless transactions through banking solutions are easy and error-free.

3. Better Customer Experience

Nowadays, customer experience is at the heart of any business. In the BFSI industry, users demand apps with good usability, better user interface, and stable performance at peak loads. With end-to-end performance testing and automation in the banking industry, enterprises building banking applications can deliver a great user experience and improved performance.

4. Security and Privacy

With cyber-attacks being common, the topmost priority of financial organizations is to protect customers’ important data and ensure safe transactions. End-to-end testing can enable these companies to perform vigorous security testing during all stages of application development.

Major Challenges in Implementing End-to-End Testing in the BFSI Industry

With ever-changing and cutting-edge technologies, the banking industry has been a forerunner in adapting and scaling up to new technological changes. However, BFSI enterprises face a lot of challenges in implementing new technologies, like end-to-end testing. 

1. Maintaining Effective Data Transfer During System Migration

Transferring data is a big challenge to banking organizations when migrating from the old system to the new system, as these data are very sensitive and important for their clients. In this stage, implementing end-to-end testing will complicate the whole testing environment.

2. Providing Real-time Updates

With a lot of devices and OS available in the market, it is necessary for testing teams of financial companies to verify the stability of their banking apps and provide real-time updates for their app users. However, this is a big challenge for banking companies, as they have to track and monitor their apps 24*7 to identify and solve various real-time issues.

3. Meeting Security Requirements While Testing

A major challenge BFSI organizations face is testing their apps that meet security requirements. Banking enterprises are finding it challenging to deploy a secured solution to test their apps as they deal with sensitive and crucial data.

4. Maintaining Operational Consistency Across Devices and Systems

Banking apps require to operate consistently across different operating systems, browsers, and devices. Owing to the fragmentation in OS, browsers, and devices, banking enterprises find it difficult to deliver error-free experiences to their customers. With many versions of iOS and Android devices available in the market, it has been a challenge for BFSI companies to upgrade their apps to support their respective versions.
