What cannot be tested on a mobile farm?

On a mobile farm (a mobile platform for pharmaceutical applications), it is not possible to fully verify:

• Hardware features of the device, such as sensors, GPS, accelerometer, if they are not supported by the pharmaceutical application.
• Performance and load under real conditions, especially with unstable internet connection.
• Interaction with external medical devices or equipment, if there is no physical access to them.
• Security at the operating system and hardware level.

Often, a mobile farm is used for functional testing of the interface and basic logic, but it does not replace full testing on real devices and in real operating conditions.
