End-to-End Testing of Mobile Banking Apps


, on

Banking apps are the real flag bearers for a reputable and respected bank because banking is a severe business. They must be carefully tested because mobile apps and online banking are the preferred touchpoints.

Numerous financial services, such as money transfers, user information, available funds, and credit card information, must be provided by banking apps. The program must therefore function without a hitch and be compatible with every operating system. Banking app testing is the only approach to guarantee complete security and performance.

Due to their ability to support several tiered workflows and extensive feature sets, banking apps have a complicated structure. Additionally, these apps’ data protection levels should be immaculate because they deal with sensitive data, such as users’ financial and personal information. Since a lack of test coverage can result in data breaches, money losses, financial fraud, and other crimes, software testing for banking applications need to be built with the utmost precision.

Why do banks need continuous mobile banking app testing?

Banking applications are renowned for their intricate networks, substantial transaction volumes, multi-tiered functionality, and dependence on older systems. It is necessary to continuously monitor, evaluate, and optimize the application due to the intricate network of systems, apps, and players. Mobile banking applications now integrate with the core banking systems and occasionally with third-party applications in the era of Open Banking and the digital eco-system.

  • Bug-free banking applications: 

Testing the mobile banking application provides the development team with a proactive means of tracking, foreseeing, and managing performance and security problems. The company’s reputation suffers greatly when a product is released with several bugs. Banks must use a continuous testing plan to prevent performance issues.

  • Enhancing user experience: 

The younger, more tech-savvy generation is driving a significant increase in mobile banking usage. Your mobile banking software must be well-tested to win customers’ trust and loyalty. Applications with bugs are poorly tolerated by Gen Z, who also demand streamlined services across all touchpoints. Their app reviews are also very important for the popularity and overall branding of the app.

  • Maintaining speed and quality:

Delivering high-quality applications quickly is necessary for the competitive climate. Banks find it challenging to conduct rigorous testing since their internal quality assurance (QA) staff are overburdened. By conducting thorough due research, a QA partner can assist you in navigating the market. Additionally, several automated tools help QA teams do tests quickly without sacrificing quality.  

  • Conformity with laws and safety standards:

Protecting user information is a top responsibility for banks because they work with sensitive data. Software with flaws puts users’ data at risk and leaves them open to attacks from nefarious actors. Developers and testers should conform their security protocols to national and international security rules and regulations since new features are often implemented.


The client decides to introduce a mobile banking software that will allow users to make payments and manage their money while on the road to draw in new consumers and enhance the experience of existing ones.

The testing crew faced many obstacles as a result of this ambitious undertaking. The bank decided to create an application for the two most widely used platforms to reach a bigger audience, and it required mobile app testing services. A thorough testing process was required because the program has to work with the widely fragmented mobile operating systems (iOS 9.3.5 and above; Android 4.0.1 and above). Additionally, Android is supported by various manufacturers’ various devices, many of which have novel characteristics that need to be considered.

The program lets users behave as though they were at a bank branch to establish a favorable user experience. As a result, the software must have intricate functionality and respond quickly to shifting circumstances. The system’s risk-prone features and locations must be tested promptly and precisely.


For the application to function correctly, the smartphones must be running Android 4.0.1 or iOS 9.3.5 at the very least. The testing team decided to test the devices (over 20) that bank clients use most to address the fragmentation challenge and ensure adequate device coverage. This method assisted in meeting the needs of the great majority of consumers and quickly resolving any problems.

The project’s implementation needed tight cooperation between the testers from ScienceSoft and those from the bank. The program should be highly responsive and complicated, so standard functional testing was out of the question. The testing group instead used contemporary Agile testing techniques, like Beta testing for each stable release candidate.

Agile testing was entirely transparent for the customer because the test scenario was developed in response to insightful feedback from staff members of various bank departments. Before the software was released, headspin and the customer’s staff examined it via beta testing, which gave them time to review the product thoroughly.

The mobile testing team at ScienceSoft maintained the necessity to keep the app’s top rankings on the regional market for mobile banking apps in mind when doing regression tests. The testing team created an 89-test regression testing scenario in collaboration with the customer. This scenario facilitates rapid and flawless software updates while reducing testing time.

Essential Steps to Boost the Results of the Banking Application Test

  • Frequently test the applications in the banking area.
  • Take charge of and take part in all testing team tasks, including gathering requirements, reviewing them, and creating a testing scenario
  • Encourage participation from actual users to obtain the most accurate findings.
  • Make use of both human and automated testing
  • Since emulators cannot wholly replace testing on real mobile devices, use genuine devices instead.
  • Gather suggestions to enhance the functionality of your app.


There is little doubt that mobile banking applications will be the secret weapon for the future of digital banking in the ‘Apps for everything’ age. While evangelizing and developing cutting-edge mobile apps, the human experience would matter more than the client experience. The future will be defined by a rapid and comprehensive analysis of the quality of mobile applications employing the best testing techniques and automation expertise.

Traditional QA approaches need to be reconsidered with adaptable quality engineering practices to portray mobile banking quality in its best state for a seamless experience. HeadSpin is an excellent platform to test banking applications and is highly recommended for testing such apps.
