To create a winning mobile testing strategy, it's essential to understand the challenges of mobile app testing, including device fragmentation, screen size and OS fragmentation, localization, and different types of mobile apps. A mix of real devices and virtual devices (Android emulators and iOS simulators) should be used as part of the mobile testing strategy. There are three main points of focus for mobile application testing: functional testing, hardware device testing, and attribute testing. An integrated approach that incorporates both manual and automated tests is recommended, with automation covering 80% of test cases and manual testing covering the remaining 20%. Mobile beta testing allows teams to validate applications with real users in real-world environments, while choosing the right automated testing framework is crucial for effective and efficient testing. Finally, considering cloud-based real devices or in-house mobile testing options can help scale and automate testing efforts.
