Mobile Device Testing, Simulator vs Emulator

There are countless mobile devices and applications, which aims to attract their target users. Thereby, it becomes highly important for the developers to cross-check the features and functionalities of an app, before it is launched on any platform. The mobile device and application testing companies employ different sorts of software and hardware utilities, and follow various testing procedures to evaluate an app before its launch.

Simulator Testing (Simulation) – It is a process to perform a Real Mobile Device Testing. The testers make use of real mobile devices to check the features, qualities, and functionalities of their client app. The key benefit of this process is that it ensures how an app will work in a real mobile device.

Emulator Testing (Emulation) – It is a process in which a specifically designed software program emulates the features and functions of any mobile or computer. Then, it creates a suitable or desired test environment to carry out the testing.

Some of the key differences between the above-mentioned methods are discussed below.

Simulator Testing

  • The objective of this process is to simulate the internal state of an object as clear as possible before performing the testing.
  • This method is most favored while understanding the external behaviors and features, like calculators and global positioning system, of a mobile device.
  • Simulators are programmed with a high-level language, making them more typical than the emulators. This proves to be difficult for few entry-level developers. Sometimes, it is also difficult to debug with simulator testing process.
  • This mode requires you to install only a small portion of the software program.

Emulator Testing

  • The objective of the emulator is to imitate or emulate the behavior (including functions, features, and environment) of the mobile devices on which an app has to be tested.
  • This proves to be ideal while testing internal features like storage, RAM usage, hardware performance, etc. of a mobile device.
  • Debugging is easier because of the machine level language used by the program.
  • Software program is installed completely.

When it comes to checking the functionality of a program in real-time scenarios, simulators are a favored pick. When there is a requirement of checking the app in some specific situation and produce readable (text) test results, emulators prove to be ideal.
