Strategies for Mobile Device Testing and Quality Assurance

By Terence Oi, Vice President, Financial Services and Insurance, NTT DATA, Inc.

In a world where seconds can translate into millions of dollars, Wall Street customers want access to personal, business, and proprietary financial information wherever and whenever. High-quality mobile applications have become key to establishing a differentiated, credible digital presence. With the proliferation of devices and the rapid pace of upgrades, establishing effective and agile testing strategies is critical to success.

Every day, the digital bar gets set higher. Digital banking customers are demanding aggregated mobile content in a composite format that includes text, charts, streaming video, portfolio analytics, and real-time market alerts to support use of their mobile devices as powerful productivity tools. In addition, customers want to incorporate interactive communications with analysts, brokers, and traders directly within the applications.

Naturally, customers want all of this content incorporated in a mobile experience that provides an immersive experience. In other words, users want device-agnostic, advanced analytics and communication in the palm of their hands. To complicate the situation, Bring Your Own Device (BYOD) is a reality, so internal stakeholders require all of this real-time access to applications on their own devices.

How does a financial institution provide customers and employees with a world-class, secure digital experience, given the significant reputational risk associated with even small faults in digital/mobile applications? The applications must have the same functionality, performance, and usability on a variety of multi-sized, mobile phones, tablets, and eReaders, each with its own resolution, platforms, and operating systems.

To be effective, mobile applications must also accommodate:

  • A continuous cycle of updates
  • A variety of connectivity and network speeds
  • A wide spectrum of user expectations and technical know-how

Importantly, the platform must be stable and the information reliable, trustworthy, and secure to protect client information and intellectual property (IP).

The question financial institutions must ask is: How do I ensure that my IT organization rolls out mobile applications securely, comprehensively, and with compressed testing cycles? The answer is robust, yet cost-effective, quality assurance and testing (QAT).

Mobile Testing Best Practices

With the proliferation of devices and content, QAT of mobile applications is different and more challenging than testing for the desktop and Web. As a result, it can become a crippling bottleneck in the application development process. Organizations need to be smarter than ever about how they manage finite testing resources to support increasingly diverse technical and user requirements.

Testing is typically resource intensive and is under increasing time pressures as development cycles shorten. Answers to these three questions help prioritize finite resources and define the core scope of an effective mobile testing program:

  • What combination of devices and operating systems should be tested?
  • How is my application performing on a specific device or in the real world?
  • How do I accelerate the mobile testing process?

A mobile testing strategy should always begin with analytics of users, applications, devices, and operating systems. What are the most used applications, devices, and OS? What is the customer profile associated with each segment? Organizations can then analyze risk and make informed tradeoffs among speed, cost, device coverage and test thoroughness by analyzing and understanding current usage.

Speed and Repeatability Require Focus and Flexibility

Once you define top priorities and critical scope, you can begin to build out the mechanics of a repeatable mobile test execution. It is critical to test on real devices using real browsers and important to control mobile devices remotely and leverage automation using proven tools. Understand how to leverage cloud-based environments to reproduce mobile devices, thus curtailing costly infrastructure investments. Develop a regression testing strategy that expects frequent application upgrade cycles that are externally driven, as mobile device operating systems are updated with increasing frequency.

Experienced mobile testing and QA providers offer cost savings, flexibility, subject-matter expertise, and proven processes, tools, and metrics. Leveraging on-demand, cloud-based, devices and mobile browser reduces infrastructure investments. Automation tools reduce testing cycle times by 30-40%.  These factors are critical to cost effectively providing users with the mobile usability, functionality, and performance they need with the security your company requires.
