This article will examine four main approaches used in mobile application testing: in a cloud, based on emulation or devices, and crowdsourcing.
Based on emulation
Using emulators is a good way to start the testing. They help identify most errors at the early stage of the software development life cycle. If there are no components on hand or the required device is busy by another tester, what comes to help is emulators which can fully imitate the behaviour of the smartphone or tablet. Initially designed for testing, they are part of SDK development. Conveniently, emulators are launched on PC or servers or more powerful devices than smartphones. But due to this, some errors may go unnoticed or give a misleading impression, for instance, response time or program performance.
