Emulator or Real Devices, which is better?
Why we should abstain ourself from using simulators/Emulators for Automation testing or Manual Testing altogether like:
- Testing on real devices is the best solution for uncovering bugs (regression included) and getting accurate results.
- Sometime things may seem to work on the simulator but may fail to work on Real Device,this can easily be deduced from the ongoing Native/RN task which quite often fails to work on OEM's.
- Testing is being conducted in an environment that is not real and we are utilizing System hardware which cannot be compared to the Mobile Hardware.
- Simulators are not reliable since hardware features like GPS, camera, etc (though we only use GPS) are either simulated or hardcoded in them and they are slow for automation purposes.
This Blog beautifully explains why we should `not use the simulator as the only source of the test environment`
