The advanced tools have made it easier for businesses to create cross-platform mobile apps by leveraging a single codebase. The developers can further use specialized tools to update the application quickly across multiple platforms and devices. However, it is always important for the business to customize the application for each platform to boost its usability and user experience. Likewise, the business must test the cross-platform mobile app thoroughly and effectively to make it popular and profitable in the longer run.
5 Cross-Platform Mobile App Testing Best Practices
1) Define the App's Functional Requirements Clearly
To identify all defects and flaws in the application, the QA professionals must understand its functional requirements clearly. The clearly-defined functional requirements will further help the business to test the app effectively across multiple devices, platforms and networks. The business must prepare a comprehensive list of functional requirements of the app, and share it with the testers from the very beginning. The list will make it easier for testers to identify the expected bugs or defects in the application by testing the app in most appropriate scenarios.
2) Follow Guidelines of Each Mobile Platform
Each mobile platform requires app developers to follow certain guidelines. So each business must follow the standards recommended by each mobile platform on functionality, content and user interface design (UI). When the app complains with these guidelines, it will run seamlessly on the mobile platform. The business need to ensure that both developers and testers know the guidelines recommended by each targeted mobile platform. The understanding will help QA professionals to test the application on each platform according to the regulations and standards.
3) Maintain Balance between Simulators and Real Devices
While testing a cross-platform mobile app, no business can afford to invest in a wide variety of mobile devices powered by major mobile platforms. So many businesses use simulators and emulators to test mobile apps without spending a lot of money. But each business must remember that emulators and simulators do not provide 100% accurate and reliable test results. Here, it must create a test lab containing both real devices and emulators. It is also important for the project manager to split the tests across real devices and emulators. For instance, emulators can be used for performing unit testing and integration testing. On the other hands, testers must use real devices to conduct device profiling and regression, performance, compatibility and security testing.
4) Pick the Right Cross-Platform Mobile App Testing Tools
No business can rely on manual testing to assess a cross-platform mobile app effectively. It is always important for the business to set up a test lab maintaining of the right test automation tools. Each business has the option to choose from several cross-platform mobile app testing tools including MonkeyTalk, M-eux, eggPlant, Squish, DeviceAnywhere and MobileCloud. Most of these tools are cloud-based, and assess apps through cross-platform scripts. But the business must remember that each of these tools has its own strengths and shortcomings. So it must pick the right tool and framework according to specific requirements of the project. A business can also consider investing in testing tools that support multiple targeted mobile platforms.
5) Test the App in Real-User Conditions
To assess a mobile app's functionality, performance and user experience accurately, testers must test it in various environments and conditions. It is also important for the business to explore ways to test the cross-platform mobile app in real-user conditions. A business also has a number of options to test the mobile app in real-user conditions. For instance, it can facilitate field testing to make it easier for testers to assess the application in various conditions and under different network speed. Likewise, a business can opt for crowdsourcing testing to get the applications tested by real users across different devices, platforms and conditions.
It is also important for the business to make and implement a custom testing strategy for each cross-platform mobile app. The comprehensive strategy will make it easier for QA professionals to assess the application throughout across multiple platforms and devices according to specific requirements and objectives of the business.
