As far as improvements in the quality of mobile apps are concerned, nothing can be better than the conclusions drawn from accurate device testing. However, speeding up mobile app development is more than just rapidly developing code rather than identifying problems and ensuring a straightforward user experience that is evident long before the app ever reaches the end user. Real device testing leads to the world of reality in terms of performance, nuances, and problems that could have easily been missed if it was done in emulated settings.

Development teams investing in real device testing can sidestep the pitfalls of the mobile landscape, where many device configurations, operating conditions, and user interactions converge. Furthermore, strong mobile app testing techniques ensure your application works and functions on various devices. 

So, without further ado, let’s explore the key benefits of real device testing and provide strategies for implementing it effectively within your development process.

Why Is Real Device Testing Imperative?

Let’s examine why real device testing is so essential to the mobile app development process:

  1. Device Diversity

The need for testing on real devices stems mainly from the diversity of the mobile device market. Different devices have differing features, screen resolutions, and hardware capacities, impacting app performance. Mobile app testing on real devices allows you to develop a general idea about the behavior of your application in users’ hands. Developers gain insights into real-world usability, accessibility, and overall user satisfaction – factors that emulators cannot replicate perfectly.

  1. Network Conditions

Another critical aspect of real device testing is its ability to showcase the actual performance of your application under various network conditions. Users might be accessing your application on the go, which means fluctuating network speeds and connectivity quality become critical components of the user experience. Testing how your app manages these changes is essential to prevent user frustration and negative reviews.

  1. Interactions and Notifications

Interactions with other applications and notifications significantly affect your mobile app’s functions. Real device testing allows you to witness firsthand how your app copes with interruptions, be it incoming calls or updates from other apps. Such interactions are complex to simulate in emulated environments but are crucial for ensuring a seamless user experience.

  1. Device-Specific Features

Another consideration that impacts how our app is built is the device-specific features, including cameras, GPS, fingerprint scanners, and gyroscopes. Mobile app testing using physical devices allows developers to work directly with these hardware elements to test their integration to ensure flawless compatibility and performance across different brands and models.

  1. Operating System Updates

Furthermore, operating system updates can introduce unforeseen issues that can significantly disrupt user experience. Through real device testing, developers can preemptively uncover compatibility issues with new OS versions, patches, or even brand-specific alterations that might result in app instability or crashes.

Integrating Real Device Testing into Agile Development

Incorporating real-world device testing into Agile development methodologies guarantees the excellence and dependability of mobile applications on diverse platforms and devices. The following are some essential tactics for successfully incorporating real device testing into Agile processes:

Automation Integration: Automation is a significant component of agile development; it works just as well when testing mobile apps. Automating the repetitive tests on real devices is fast and easy to conduct several tests many times with little cost, detecting and solving issues early. Nevertheless, even with established automated testing software, manual testing on real devices will still be unavoidable since it is only through manual testing that user experience problems can be discovered.

Continuous Integration and Delivery (CI/CD): With the help of real device testing, CI and CD environments get a loyal comrade. Making it part of these processes allows each build to be tested across a spectrum of real devices. This practice ensures that bugs or performance issues are highlighted well before deployment, thus avoiding delays and rework.

Collaborative Approach: Agile principles must be observed to achieve success for any agile method. Collaboration enables real device testing to unite developers, quality assurance teams, and user experience professionals. The team members better understand the users’ viewpoints when interacting with real devices. They are well-positioned to deliberate and make decisions on the development of the application based on facts.

Cloud-based Solutions: Although establishing an in-house device lab may be too broad of an operation and rather costly and labor-intensive, cloud-based services provide a feasible option. It is a great way to use the device lab in the cloud, allowing teams to access various types of devices online and test from anywhere globally. It is especially relevant for distributed teams or those pursuing cost-saving opportunities to eliminate the costs incurred from keeping physical devices.

Although establishing a device lab within your company may seem complex and resource-intensive, cloud-based services provide a good substitute. Teams can access various devices online and conduct testing from any location using a cloud-based device lab. This flexibility benefits remote teams or people trying to save money on physical device maintenance.

For example, LambdaTest is an AI-powered test orchestration and execution platform that lets you run manual and automated tests at scale with over 3000+ real devices, browsers, and OS combinations. Using the LambdaTest, teams can test their mobile and web applications on numerous real devices and browsers.

On the other hand, the platform is an ideal choice for Agile teams concentrating on improving the testing processes due to abilities like live interactive testing, automated testing, and smooth integration with CI/CD pipelines.

Development teams may ensure thorough testing across various real devices and scenarios and expedite their mobile app development lifecycle by employing cloud-based solutions such as LambdaTest.

Maximizing Test Coverage with Smart Device Selection

It is critical to pick an intelligent set of devices that both optimize the testing process and ensure a diverse representation of your target user population to ensure complete test coverage through smart device selection.

Smart Device Selection: It is not practical to test every device globally, but prioritizing the intelligent choice of devices to test is critical. Decisions to enrich these experiences can be made through market data analysis that helps realize the most popular devices among the target audience. Not only the latest and hottest models addressed are mentioned here, but also a variety of older equipment that numerous running participants may use.

Balanced Test Matrix: Maintaining a sample size that has high-, mid-, and low-range devices is the best test matrix to ensure the spectrum is measured performance. Suitable spec devices highlight the best-case position, but performance level limits often appear on mid-range and budget devices. It creates a sense of relatability between your mobile app testing plan and real-life usage cases.

Categorization of Test Scenarios: Systematic categorization of test scenarios based on device features can also enhance the efficiency of your testing procedure.

Specific test cases will apply universally, while others will be specific to devices with certain hardware elements or software capabilities. By classifying tests accordingly, you can more effectively allocate devices and manage the testing workload.

Challenges and Solutions in Real Device Testing

Real device testing offers many benefits but also a few drawbacks. Let us discuss some challenges and look at how we can address them.

Challenge: Device Management

One of the primary concerns is the sheer number of devices to manage. Setting up, maintaining, and updating a large inventory of devices requires significant effort and organization. 

Solution: Employing a device management platform can help streamline these processes, simplifying the task of device provisioning and monitoring.

Challenge: Cost Considerations

Another factor to consider when implementing a real device testing strategy is cost. The investment in devices, maintenance, and the space required to house a device lab can add up. 

Solution: As a cost-effective alternative, renting time on devices in a cloud-based lab can alleviate the upfront financial burden while giving access to a broader range of devices.

Challenge: Security and Privacy

Data security and privacy issues are heightened when using real devices, especially if sensitive information is involved. Robust security policies and procedures must be in place to protect the test data and the devices themselves.
