Understanding Mobile Fragmentation

Various devices have different operating systems and screen sizes. The diversity in mobile devices, operating systems, and screen sizes combined is termed mobile fragmentation. The cause of mobile fragmentation is the frequent launch of new devices in the market. The addition of new devices not only raises fragmentation but also increases the complexity and challenges of performing cross-device testing.

Key Factors Contributing to Mobile Fragmentation

To address mobile fragmentation, you must first understand the factors involved in its rise. Here is a list of key factors.

Device Diversity

Mobile devices comprise smartphones, tablets, and foldable devices. Companies manufacturing these mobile devices introduce unique specifications and features to their devices, increasing the range of mobile devices. The diversity raises challenges for developers and testers in ensuring consistent behavior across multiple devices.

Operating System Versions

The devices in the market have distinct operating systems such as Android and iOS. The operating system and its versions create multiple testing scenarios. And testing them all is necessary to ensure the compatibility of software applications across all devices.

Screen Sizes and Resolutions

Devices differ in screen sizes and resolutions, which can affect the usability of software applications. Therefore, developers and testers must ensure the software application works seamlessly. This is significant in providing a seamless user experience across all screen sizes and resolutions.

Hardware Differences

Several hardware components are used to manufacture a device. Different devices are manufactured using different hardware components. They have different processors and RAM that impact the performance of a software application. Therefore, it is essential to address mobile fragmentation to ensure software applications perform effectively across all devices.

Custom Manufacturer Software

The manufacturers of mobile devices add their customization, which can affect the behavior of the software applications. Therefore, the bugs and other issues that may arise due to these customizations need to be handled seamlessly.

Cross-device Testing

Cross-device testing is a strategy to ensure the correct and consistent working of software applications across multiple devices. It is used to address mobile fragmentation and ensure seamless performance. Cross-device testing improves the visibility and usability of software applications across all devices.

Cross-device testing is important due to its following primary goals mentioned below.

• Ensuring Consistency: A consistent software application is essential for providing a seamless user experience. Cross-device testing is conducted by the testers and developers for the same. It ensures the software application is functioning the same on every device.

• Enhancing Usability: Cross-device testing enhances the usability of the software applications. It ensures the visibility is consistent across all devices and is user-friendly.

• Improving Performance: Cross-browser testing is significant for improving performance. It ensures the working of software applications is not affected by the device hardware component.

• Maintaining Compatibility: Different devices have different operating systems and their versions. Cross-device testing maintains the software applications and handles the issues that can lead to crashes and poor user experience.

Strategies for Effective Cross-Device Testing

Mobile fragmentation can lead to various compatibility, usability, and functionality issues. Furthermore, various other issues and bugs may be detected. Therefore, testers must adopt the following strategies to address mobile fragmentation through cross-device testing.

Prioritize Devices and OS Versions

Today, we have various devices on the market. Testing your software application on every device is not economical. Therefore, you must prioritize devices and OS versions. The prioritization must be done by researching and analyzing the most used devices by the end users. Furthermore, prioritization of devices also helps to manage resources and develop the software application under budget.

Use Mobile Site Tester

Setting up real devices for testing a software application is not cost-effective. You need tools that will allow you to test your software application on multiple devices without setting up actual devices. You can use Mobile Site Tester for this. It is a powerful tool that lets you mimic real-world scenarios. The tool also lets you:

• Simulate different devices and replicate their behavior.
• Identify layout issues caused due to the variation in screen size and resolution.
• Identify bugs at the early stage of software development.
• Monitor the performance of software applications in different network conditions and under distinct hardware capabilities.

Real Device Testing

Testing your software application on real devices is significant for understanding its performance in the real world. It allows you to identify issues related to network conditions and hardware differences. Therefore, you can perform real device testing in the following ways.

• You can build a device lab. Here, you can set up actual physical devices to test your software application. However, this will require a significant amount of time and money.

• You can even use a device cloud. These are cloud-based platforms that offer you access to real devices for testing your software applications. Here, you do not require a physical setup.

Automated Testing

Cross-device testing is a time-consuming process. It requires a lot of effort. However, automated testing can effectively reduce the testing time. It allows you to test your software applications thoroughly across various devices, as mentioned:

• In automated testing, you can create test scripts that cover all scenarios. Furthermore, these scripts could be executed automatically to test software applications.

• Through automated testing, you could integrate your test into the CI pipeline. The test scripts are automatically executed when updates or code changes are made. It allows the early detection of bugs.

Cloud-Based Testing Platforms

Cloud-based testing platforms are another strategy you can opt for to address mobile fragmentation. It lets you test software applications across devices and operating systems over the internet. The cloud-based testing platform saves your resources as you do not have to set up a physical device lab. Mobile Site Tester is among the most used cloud-based testing platforms.

Continuous Integration and Continuous Deployment (CI/CD)

While testing software applications, various code changes are made to debug and fix other issues. These changes can raise several other bugs and issues. To ensure code change has not affected the functioning of the software application, you must integrate it into the CI/CD pipeline. This will automatically test software applications whenever a code change is made. Furthermore, when a software application successfully passes the test, it is automatically deployed for quick feedback from the end user.

Tools for Cross-Device Testing
