Did you know that around 5 billion people worldwide are glued to their mobile devices, dedicating an average of 3 hours and 15 minutes daily to screen time? Mobile apps are more than just digital tools – they organize our days, entertain us, and keep us connected. But as our dependency on these apps escalates, so do our demands for their performance to be nothing short of perfect. So, how can developers ensure their app excels for every user, across every device and network, every single time?
Mobile app testing at scale is about guaranteeing a smooth, error-free user experience for every download on any device. In this article, we'll review the importance of mobile testing, common mistakes to avoid, and best practices for mobile app testing at scale. Let's start!
It is important to test all software, and mobile apps are no exception. Bugs in production are much more expensive to fix than bugs in prototype or pre-release stages. This principle is at the heart of the Shift-Left movement, which advocates for testing early and often in the software development lifecycle.
To successfully implement a Shift-Left strategy in your development workflow, consider the following actions:
You should test more if:
Choosing the right testing strategy is deeply influenced by the business's unique needs and any regulatory requirements it must meet. Ensuring compliance with laws and standards is crucial for apps in regulated industries. Beyond compliance, all businesses should focus on several key areas of mobile testing:
Mobile app testing introduces unique challenges, primarily due to the vast diversity of devices and the complexity of managing different app versions.
Automating mobile app tests is challenging due to:
These challenges lead to three key outcomes:
The complexity and resource demands of automated mobile app tests elevate the skill level required for effective testing and increase the workload of maintaining test scripts. This shifts the balance of testing ROI, making it crucial to decide when to employ manual versus automated testing.
Manual testing remains invaluable for scenarios where the nuance of human observation is vital, such as user experience and usability testing. In contrast, automated testing is most beneficial for repetitive, data-intensive testing scenarios where consistency and speed are priorities.
To get the right device mix for your business, you will likely use a mixture of emulators, real devices in-house, and an outsourced solution for mobile app testing.
An emulator is a software tool that simulates the environment of a specific hardware or operating system, allowing developers and testers to run applications on their computers as if they were using the intended devices. Official emulators, like Android Studio Emulator and the iOS simulator, are preferred for their reliability. They're crucial for mobile app testing due to their ease of setup and use. Still, they may not fully replicate the performance of real-world devices, which is why it is important to understand their limitations.
Many of Global App Testing's clients use emulators to an extent, but to bookend the process with edge cases and diverse geographies with real-world devices, in-house or via Global App Testing.
Physical devices can solve some of the above problems. To do this, you should purchase a diverse set of devices, ensuring that your users' most important devices are well-represented in the device suite. You can attempt to automate the tests on these devices, and you should document and share results within a test management platform like TestRail.
This will solve hardware interaction and accurate gesture testing, but there are clear downsides to doing this in-house.
Our overall view on in-house physical device farms is that it is undoubtedly useful to have a small set of physical devices for quick smoke tests and other tests a developer or QA may wish to execute locally, but as a comprehensive testing solution, physical device farms in-house are just too complex an undertaking to be managed in-house, especially for smaller companies.
Mobile cloud testing solves the financial burdens associated with purchasing and maintaining various mobile devices. This approach provides access to a comprehensive array of device types in the cloud, enabling mobile application testing, deployment, and management on virtually any device-OS combination. While challenges such as privacy, security, and reliance on internet connectivity exist, the advantages of mobile cloud testing are significant, supporting diverse testing needs across various scenarios.
Global App Testing can help you test applications using a distributed "crowd" of over 90,000 testers. This gives us a range of software versions, devices, environments, and regions and allows us to test your product in different conditions on your behalf. You can stipulate test conditions; otherwise, we'd happily discuss the preferred device distribution.
Crowdtesting offers significant advantages by enabling manual testing of the app from diverse viewpoints. Testers can contribute valuable feedback on app performance and usability while affirming the app's alignment with user stories.
Unlike web applications, mobile apps are installed on devices, leading to a challenge in testing due to the variety of versions users might retain without updating. Testers must ensure compatibility across both new and old versions, including unnumbered development versions, complicating tracking and testing efforts. Additionally, adherence to App Store guidelines introduces further complexity, influencing testing and release strategies due to strict compliance requirements.
Version control is a system used to manage changes to source code and other development files, tracking the history of changes and enabling developers to compare versions and revert to previous states if necessary. It facilitates collaboration by allowing multiple developers to work on the same files simultaneously, managing changes and merges to prevent conflicts and ensure a coherent codebase.
In the context of mobile app development, version control is crucial for managing the different versions of an app, from the development and testing phases through to release. It helps maintain a stable development environment, track bugs, and implement fixes across all tested and developed versions.
Version distribution focuses on the complexity of ensuring every version of the app in users' hands is functional and free from bugs. In contrast, version control efficiently manages and tracks changes in the app's codebase. Together, these aspects are fundamental to delivering a superior mobile app experience to users and achieving operational efficiency in development teams.
