The testers need to ensure mobile application performs uniformly across all devices.
  • Operating System Fragmentation: The availability of different mobile operating systems is another challenge in selenium mobile testing. There are multiple versions available of mobile operating systems i.e. Android and iOS. The end users prefer using different versions. Therefore, mobile applications must be working seamlessly on all. However, handling iOS fragmentation is easier than Android due to immediate updates from manufacturers and carriers. In Android, the end users delay updating to a newer version which makes it necessary for developers to take every version into account.
  • Difference in User Interface: Every platform has specific guidelines for design and user interface. The developer needs to ensure that mobile applications meet these rules. This also offers a consistent user experience on all platforms. Therefore, mobile applications need to be tested for both iOS and Android to fulfill these guidelines. For iOS you need to meet the Human Interface Guidelines and Material Design for Android.
  • Browser Compatibility: Ensuring the seamless functioning of mobile applications across multiple browsers is essential for cross-platform compatibility. The availability of various browsers adds up to the challenge in Selenium mobile testing. This is because each browser handles mobile applications differently and supports different features of HTML and CSS for different extents.
  • Performance Variability: To ensure a smooth user experience for the end user, you must test for performance variability across all devices and platforms. Since mobile devices have fewer hardware components as compared to desktops, it brings up challenges in conducting selenium mobile testing. The testers need to optimize mobile applications for lower memory usage and efficient CPU utilization.

Best Practices for Selenium Mobile Testing

  • Use Appium for Mobile Testing: It is recommended to incorporate Appium with Selenium to conduct mobile testing. An open-source automation testing tool called Appium will increase Selenium WebDriver’s functionality. With Appium, you can create tests that use a single API to execute on both web and mobile applications. You are not required to modify the code for every platform.
  • Writing Platform Independent Tests: Writing different test scripts for every platform is inefficient. Therefore, you must write platform-independent tests. It helps in reusability and maintenance of test scripts. You may implement the Page Object Model to organize test code by separating page-specific actions and elements. This makes it easier to maintain the codebase.
  • Handling Different Viewports: A mobile device varies in screen size. Therefore, you must test your mobile application for every screen. Along with the screen size, you must also consider orientation. You must also select elements dynamically as per the size and orientation of the screen.
  • Efficient Test Script Management: For achieving cross-platform compatibility with Selenium mobile testing, you must integrate the framework for better test management and reporting. For efficient test script management, you must also modularize your test script. The small and readable modules will allow you to improve readability and maintainability.
  • Using Real Devices and Emulators/Simulators: Using real devices and emulators and simulators allows you to seamlessly achieve cross-platform compatibility. Real devices help you achieve accurate results with actual hardware components. You must analyze and prioritize the most used devices while using real devices. However, emulators and simulators allow testing of mobile applications on virtual platforms mimicking the actual user environment.
  • Use cloud-based platforms: Conducting Selenium mobile testing on all devices with actual device setup is not feasible. Therefore, you must opt for a cloud-based platform. The cloud-based platform provides you an extensive device coverage without actual device setup. It also lets you mimic real-world conditions. These also enhance collaboration and integration among testers and developers.
  • Automation and Continuous Integration: To test for cross-platform compatibility you require executing the same test script on multiple devices and browsers. Doing these manually requires a lot of effort and time. Therefore, automating test scripts saves time and reduces human error. Also, integrating test scripts into the CI/CD pipeline lets you repetitively test upon code change.
  • Performance and Usability Testing: Cross-platform compatibility calls for optimal performance and usability testing. It is crucial for user satisfaction. The performance testing ensures the seamless functioning of mobile applications across different devices and network conditions.
