Mobile device application development faces significant challenges, which pass through to their testing. Though the obstacles appear daunting, there are ways to mitigate such complications, improve your team’s testing effectiveness and also raise app quality.
Mobile App Challenges
- Mobile device fragmentation is rising. There are a myriad of hardware platforms, OS versions and network connection options across devices. Trying to maximize market coverage for a single app requires spanning this ever-increasing matrix of combinations with a concomitant increase in testing complexity.
- Testing budgets are not expanding, which means doing more with less, which in turn leads to deciding between in-house or outsourced testing. Outsourcing infrastructure to the cloud often reduces capital and maintenance expenditures, but outsourcing test personnel and processes is a riskier proposition that is usually hard to unwind later. Outsourcing pressure is also increasing because new expertise and sophistication is required by leading edge test frameworks and tools.
- Adding insult to injury, mobile app development requires ever faster development/release cycles. That is due to heightened competition and to end-users’ progressively shorter attention spans. Users more and more expect defects and improvements to be available in near-real time. That means testing has to constantly play catch-up so as not to become the bottleneck in the next upgrade.
Dealing Effectively with Modern Mobile App Testing
Before deciding you might be in the wrong line or work in the face of these looming challenges, let us consider five approaches that will improve your organization’s abilities to operate more efficiently while improving the quality of released apps.
1. Embrace Agile Development
This step is global to the organization. Fundamentally, it means involving all the stakeholders in the project from business managers to architects to production personnel. Depending on the delta between what you do today and how far you want to take agile development determines the size of the steps you take, but every step gets you closer to a more successful testing organization. Agile methodologies are proven to improve the ability to adapt to change, improve customer and stakeholder engagement, create more useful documentation and higher quality deliverables.
2. Value Your Automation Properly
Are you accurately measuring the value you derive from test automation? Often, more automation simply bloats maintenance tasks and increase test run times in the absence of ongoing evaluation of the tests contained within a framework. For instance, effort is commonly wasted automating tests that are better done manually, such as exploratory testing. The correct approach, customizable to your particular environment, is to measure your tests along a value spectrum. Tests such as build smoke tests are relatively easy to automate and provide high value. On the other end of the spectrum might be compatibility tests, which are necessary but probably should be lower priority.
3. Virtualize Your Testing Resources
Virtualized services and virtualized platforms are both relatively inexpensive in terms of infrastructure, setup and ongoing cost. They can be used on both the client and server sides of mobile applications. You will use less costly hardware and gain the ability to scale almost linearly, which is especially valuable for performance, load and stress testing.
4. Improve Your Ability to Test on Both Emulated and Real Devices
Testing a multi-platform mobile app on real devices is probably a non-starter for in-house deployment depending on the complexity of the instance matrix combining devices, platform capabilities, OS versions and network connectivity options. On the other hand, you cannot achieve a sufficient level of quality confidence with only emulators, which should by the way be deployed as early as possible in the development cycle.
The increasingly obvious answer to this situation is to employ cloud testing services that provide real-time access to a wide collection of new, sometimes unreleased, mobile devices and network operators along with built-in test and collaboration frameworks.
5. Gain Deeper Insights into the End User Experience
Simply reviewing comments and ratings in app stores is not enough anymore to evaluate how apps are performing in the field. Consider compiling in one of today’s sophisticated crash/analytics SDKs, which have vanishingly small run-time overhead. These provide real-time insights into how users are interacting with your app plus detailed reports on crashes that pinpoint problems immediately, especially if used in combination with a hotfix insertion tool.
Testing mobile apps gets harder every day, although new tools and techniques are always coming along to mitigate the difficulties. Seeing ways to improve development/test turnaround times, to optimize test automation capabilities, employing test resource virtualization and cloud-based device testing services are effective methods for maintaining the pace. Above all, keep your app’s user experiences squarely in your sights and utilize new tools for evaluating their behaviors and problems.
