Some common challenges faced by mobile application testing team are-

Deployment of the application and its compatibility across various devices, which have varied operating systems like Android, iOS, BB, Windows, and so on. The version of the operating system also varies like iOS 5.x, iOS 4.x, BB 6.x, and so on. Cloud computing offers simulators where the testing team can automate, deploy, and test the mobile app. However, there are some problems testing in a cloud environment, which include the subscription model, lock-in, high cost, internet connectivity issue, and such others.

Some other top strategies in mobile app testing are as follows:

a) Device emulator: These are highly cost-effective allows testing to be done in more efficient and faster way. The tester can perform the bulk amount of testing in a well-instrumented environment. You can use the device emulator with different options like licve network, bypassing the network, via modem, good scripting language, and so on.
b) Remote real device in cloud: If you have access to remote real device, then you can test it on remote network (live). This is a great solution for testing.
c) Automated device: Remote, emulators, and other real device solutions that can support playback and script functionality are the real timesavers. They let you execute more test cases. The degree of consistency is also higher. This is the ideal solution that integrates emulated and real devices.
