Mobile-device testing. Mobile-device testing functions to assure the quality of mobile devices, like mobile phones, PDAs, etc. It is conducted on both hardware and software, and from the view of    different procedures, the testing comprises R&D testing, factory testing and certificate testing. It involves a set of activities from monitoring and trouble shooting mobile application, content and services on real handsets. It includes verification and validation of hardware devices and software applications. Test must be conducted with multiple operating system versions, hardware configurations, device types, network capabilities, and notably with the Android operating system, with various hardware vendor interface layers.

Static code analysis
Static code analysis is the analysis of computer software that is performed without actually executing programs built from that software (analysis performed on executing programs is known as dynamic analysis) Static analysis rules are available for code written to target various mobile development platforms.

Unit testing
Unit testing is a test phase when portions of mobile device development are tested, usually by the developer. It may contain hardware testing, software testing, and mechanical testing.

Factory testing
Factory testing is a kind of sanity check on mobile devices. It is conducted automatically to verify that there are no defects brought by the manufacturing or assembling.

Mobile testing contains: 
 
 mobile application testing
 hardware testing 
 battery (charging) testing
 signal receiving 
 network testing
 protocol testing
 mobile games testing
 mobile software compatibility testing

Certification testing
Certification testing is the check before a mobile device goes to market. Many institutes or governments require mobile devices to conform with their stated specifications and protocols to make sure the mobile device will not harm users' health and are compatible with devices from other manufacturers. Once the mobile device passes all checks, a certification will be issued for it.
When users submit mobile apps to application stores/marketplaces, it goes through a certification process. Many of these vendors outsource the testing and certification to third party vendors, to increase coverage and lower the costs.
