What role do a simulator and emulator play in the mobile testing process?
An emulator is usually where you are trying to test a mobile device that is not a physical device, it is totally artificial and is provided by a vendor like Android using the Android Studio and/or Android SDK. However, on any device whether a physical one or an emulated one, there are certain properties of a mobile device that can only be done via a Simulator for testing purposes ( i.e. taking a picture or photo, trying to scan a barcode, fingerprint, Face ID, etc.). I hope this helps.
For testing mobile apps, an emulator may be a desktop application that mimics the hardware and OS of the applications to be tested. A simulator does not mimic the hardware and OS, but rather simulate the basic behavior of a device.
While simulators are usually simpler, they are not as useful as emulators.
- Emulators and Simulators are utilized for Mobile testing to mimic actual devices /hardware. It's a cost-effective option in comparison to using actual devices.
- Emulators are applications which mimics Hardware and OS for the application to test.
- Simulator are applications to mimic behavior, activities of device.
