The document compares emulators and simulators used in mobile automation, highlighting their definitions, advantages, and differences. Emulators replicate hardware and software environments accurately but are tedious to create, whereas simulators model real-world scenarios more efficiently but with less reliability for debugging. Key differences include their structural complexity, processing speed, and the range of scenarios they can replicate.

1. Emulator vs Simulator
Presented by
Omnia Ashraf

2. Both emulator and simulator used to mimic the
real thing in a virtual environment. Although,
the differences between emulation vs.
simulation are quite big for mobile automation.
Before knowing the differences between the
two, let’s learn the definition of both mobile
testing approach.

3. Definition of Emulator:
Click icon to add picture
Emulator is kind of virtual device .it is a
software we run on personal computer to
mimic the particular smartphone’s
behavior.it helps to test the application on
specific device .

4. Advantages of Emulator
•The emulation technique helps to replicate the hardware and software
atmosphere of a computer system on another machine.
•It provide an authentic environment that does not require the original
system. However, the process of making an emulator is quite tedious and
time-consuming.
•You can achieve the applications or the OS that is emulated. You should
remember that there are not much differences for a user when using the
emulation method

5. Tools of network emulators:
•GNS3
•Cisco VIRL
•EVE-NG
•Mininet
•WANem
•Netropy
•CORE
•Opnet Modeler
•ns-3
•Dynamips/Dynagen

6. Definition of simulator:
Simulation is the process of creating a model of a real
world scenario for a variety of reasons including
education, preparing for an anticipated event or
troubleshooting a problem. The models used during a
simulation might be real or dramatized

7. Advantages of Simulator
•Simulators are highly accurate for ensuring the display of the
interface of an application is the same in various screen
resolutions.
•It also offers quick and simpler means to create a software
environment to test applications without replicating the related
hardware.
•Simulators surely have more uses than application testing, such
as mathematical modeling in medicine, technological
development, etc.

8. Tools of network simulator
• Cisco Packet Tracer
• GNS3 (Graphical Network Simulator-3)
• NS-3 (Network Simulator 3)
• EVE-NG (Emulated Virtual Environment – Next Generation)
• OMNeT++
• Boson NetSim
• VirL2 (Virtual Internet Routing Lab)
• QualNet
• Cloonix
• NetSim
• CORE (Common Open Research Emulator)
• Netkit
• Opnet
• Junosphere

9. A simulator/emulator not able to
mimic the following features −
 Battery of mobile device
 Mobile device’s camera
 It is very difficult to mimic interruptions like SMS
and incoming calls.
 Does not offers realistic simulation for mobile
device memory usage.

10. the Difference Between emulators and
Simulator?
Parameters Emulator Stimulator
Process
Emulation is a process of enabling one
computer system to replicate like another
computer system.
Simulation is simulating an abstract
model of a particular computer system.
Provided by Device manufacturers provide emulators
Simulators are provided by device
manufacturers and various other service
provider companies.
Internal Structure
The emulator is written in Machine-level
assembly language
Simulator is written in High-level
language.
Reliability
Emulators are reliable and best suitable
for debugging.
Simulators are less reliable and not so
suitable for debugging.
Binary translation
It includes binary translation as it
becomes much slower due to latency
It does not include a binary translation. As
a result, it is much faster as compared to
emulation.
Work On
It works on Mobile device hardware,
software, and Operating System
Internal behavior of the mobile device.
