How to choose Emulator vs Simulator vs Real Device for Software Testing

Depending upon the context, software testing can be used for various approaches. In certain scenarios, emulators and simulators can be used and in certain scenarios, real devices can be used for better results. Early testing can be done through the strategic usage of emulators to uncover basic bugs and in the later stages, the team can opt for real device testing for enhancing the quality of the test product. Ultimately the team should decide the right approach and act accordingly. Based on the testing needs, time and budget constraints, a feasible testing solution can be provided by the specific team. In this article, you will get to know how to choose an emulator, simulator or real device for software testing.

Software testing on Emulators and Simulators: 

Both emulators and simulators are software programs through which the imitation of one device is done with another. The software and hardware of the chosen devices are mimicked by emulators, which is better for testing compatibility, interfaces and calculations with different firmware versions. The debugging process can be done easily and effectively using emulators.

On the contrary, simulators do not mimic software, but, are especially considered when interactions are tested with external environments and applications. Simulators for mobile testing are a viable option as there is an inclination of simulators for mobile testing.

The environment of real devices can also be replicated. This can be done by a computer that runs the corresponding software, which in turn allows simulation and emulation of a wide variety of hardware devices.

Advantages of using emulators and simulators for software testing:

1. Ease-of-use: Device parameters can be switched easily and quickly in an emulator when compared to managing different types of actual devices. 

2. Low cost: Emulators are generally available for free and most of the devices that need to be tested can be emulated. In some scenarios, it is feasible to simulate various real-life scenarios like different OS versions, GPS coordinates, bad network coverage, low battery etc. 

Software testing on Real devices:

The test product cannot run on an emulator. In this scenario, real devices are used for testing the software by testers in a way that it is meant to be used. This means running on the actual software and hardware. For this reason, testing on a real device is considered to be a viable solution.

Advantages of using real devices for software testing:

1. User experience testing: The usability of a test product can be properly analyzed using an actual device. The performance issues can be easily noticed which would otherwise have been invisible if an emulator had been used.

2. Actual networks are being connected: The actual network (Bluetooth, Wi-Fi, carrier etc.,) is used to connect with the test product so that different outcomes can be produced in an emulator. Different network connectivity technologies that are being used for real devices and various levels of network coverages are included. It’s also good to see what happens when the device receives messages and calls and the testing process is interrupted. 

3. Reliability: An estimation of results can be known from actual devices because the actual environment is where the intended product is running.

4. Audio and video testing can provide accurate results: Video and audio inputs may not be supported by every emulator. Specific hardware and software solutions can be built for testing the quality of audio and video.

5. Testing usage parameters: An emulator cannot test the battery’s performance and usage. There will also be instances where parameters like data usage cannot be tested. Data and battery usage testing solutions can be built that help in understanding the application’s behavior. 

Conclusion: If you are looking forward to implementing virtual devices (emulators and simulators) or real devices or both for your specific project, then do get connected with a premium software testing services company that will provide you with strategic testing solutions that are in line with your project specific requirements.
