72). What are the encountered issues with cross-platform testing?

The problem typically depends on the OS/device version; while it may function correctly on one OS, it might not on another. For instance, we ran into a scenario where several modules were exploited when our programe died on iOS 5.x devices even though it was running properly on iOS 6.x version devices.

73). What distinguishes a capacitive touchscreen from a resistive touchscreen?

Touchscreen with resistance Two layers combine to create an overlay on the screen. The two forms make contact and work together when the finger is placed at any location on the screen. These can be found on the majority of entry-level phones and are reasonably priced. The drawback is that it takes some pressure to actually enter the touch. The screen sustains some degree of damage over time.

Touchscreen with a capacitive coating that can hold a little quantity of electric charge covers the entire display. The capacitance varies at the location where an operating object, such a finger, is placed on the screen, which affects the coordinates.

74). Why, in your opinion, is the usage of a monkey tool important in a testing procedure?

There are many paid tools like SeeTest, Ranorex, Silk Mobile, etc. available in the market, while good free automation tools are Calabash, Appium, Robotium for Android, and KIF for iOS, and using free tools requires some coding skills like ruby or java. Automation testing is a very subjective term that totally depends on the project needs and type of application. 

76). What factors would you take into account when choosing a test automation solution if you were to do a mobile application test?

The initial feature of the test automation tool is support for several platforms, allowing even future user needs to be readily met. The script should be highly usable overall, and the tool should meet some simple or complicated jailbreak requirements.

This is due to the fact that some customers frequently install a customised ROM on their devices, which frequently violates MDM restrictions and causes problems. The tool's capacity to support new OS versions comes next. The tool should be capable of sharing the source code, if at all possible.
