Have you built a mobile app for your business that caters to a massive user base? Did you test it in varying conditions to determine its usability and experience? If not, you must know that according to a recent research report, 51% of users are more likely to leave an app if they come across one or more errors every day.
It means if your mobile application fails to perform well on the end user’s smartphone, they might stop using it or uninstall it together in the worst cases. It may result in a reduced number of users and ultimately lower revenue generation. So, the question is, how can you deal with this problem? Well, that’s where mobile app testing companies come in. The ones who are leading the industry use device emulators instead of real mobile devices to test the on-phone applications.
Now the first question that might have hit your mind is what a device emulator is, and what its role in app testing is. So, let’s dig deeper into the details without any delay:
What is a Device Emulator?
Before we come to the device emulator, let’s first understand the meaning of “emulator” itself. Just to let you know, the emulator has got developed from the word “emulate”, which means – equal or approach equality. However, when you look at the meaning of “emulator”, you will know that – it is hardware or software that allows programs written for one particular system to run on another. Isn’t that one of the most exciting things to come across?
Suppose you have a Windows computer currently and you want to use a Mac operating system on it. So, what can you do to achieve that? Simply, get yourself the latest emulator that allows you to process that task. However, if you want to play a wide range of video games on your desktop, you can also use an emulator for that.
But, let’s be clear, we are not talking here about the emulators you just read. We want you to refer to “mobile emulators” that help you with app testing. So, now the next question is, what is a mobile emulator? A device or Mobile emulator is a virtual machine that allows you to imitate or copy the functioning of real phones and the user’s actions to see how a specific program operates. So, when it comes to app testing, the testers usually make the most of “device emulators” to carry out their app evaluation tasks.
What is a Device Emulator?
A device emulator is a software program that is used to simulate the behavior of a specific device or platform. It allows developers to test their apps on virtual devices, in order to ensure that they function correctly on all platforms.

The device emulator itself is a software program that is designed to accurately simulate the behavior of a specific device or platform. It is able to detect any changes that have been made to the code, and it is also able to run tests on multiple devices simultaneously.
Testing Mobile Apps with a Device Emulator
Testing mobile apps with a device emulator is relatively straightforward. The developer first creates a test plan, which outlines the tests that need to be run on the app. The test plan is then used to create and run tests on the device emulator. The device emulator is able to detect any changes that have been made to the code, and it is also able to run tests on multiple devices simultaneously. This helps to reduce the amount of time and money spent on testing, and it also helps to ensure that the app functions correctly on all platforms.
How do testers check your mobile app using a device emulator?
So, the next question is, what do testers do while testing the functionality of your mobile app? They utilize mobile emulators to access virtual mobile devices with different configurations, screen sizes, and operating systems and then run your mobile app on each of them. The aim is to see how your app functions on various smartphones regarding the user interface, loading times, customer experience, and, more importantly, performing various on-app tasks.
While sifting through this process, testers also look for bugs or errors in your app that might deliver a bad experience to the end user. Thus, if they find one or more issues in your app, they will fix them as soon as possible. And once they get satisfied with its performance, they will ask you to proceed with the launch process. Please note that passing your mobile app through a rigorous testing process before launch is pretty essential as it ensures your target users will like it when they use it. But to accomplish that goal, you must collaborate with an experienced app testing company first.
Now that you know what a mobile emulator means and how it works, it’s time to peep into a few solid reasons for using it.

Commonly asked questions
Can you use emulators for mobile testing?
Yes, emulators can be used for mobile testing. An emulator is a software program that allows a computer to emulate or imitate the behavior of the hardware of another system, such as a mobile device or a handheld game console. This means that applications written for a particular platform can be run on a computer.
Emulators are often used in mobile app testing, since they enable testers to run the app on multiple mobile devices, without having to acquire physical hardware. This allows testers to more quickly and easily simulate the user experience across a range of devices. With an emulator, testers can test the application in different OS versions, different device types, and different screen sizes, all from the same machine. Emulators are also useful for debugging and testing, as they allow developers to quickly identify and fix any bugs or errors that appear in their app.
For example, if a bug is found in the Android version of an app, the developer can quickly test it on an emulator running a different version of Android. This can help to identify the exact cause of the bug and help the developer to fix it. Emulators are also useful for performance testing, as they enable testers to measure the app’s performance across different devices and operating systems.
This can help to identify any areas where the app needs to be optimized for better performance. Finally, emulators can also be used for security testing, as they allow testers to test the app against different types of malicious software and threats. This can help to ensure that the app is secure and protected against any potential security vulnerabilities. In conclusion, emulators can be a useful tool for mobile testing, as they enable testers to simulate the user experience, debug and test the app, measure performance, and test security. This can help to ensure that the app is of high quality and ready for release.
Can apps detect emulator?
The answer to this question is yes, apps can detect emulators. Emulators are software programs that mimic the functions of a physical device, such as a mobile phone or computer. They are used to run apps or games that are not supported on the native device. In order to detect an emulator, an app must have access to certain hardware or software features that are unique to the native device.
For example, many emulators don’t have access to the same sensors that a real device does, such as a gyroscope or accelerometer. The app can detect the lack of these sensors and identify the device as an emulator. In addition to hardware features, apps can also detect emulators by looking for specific software features. For example, an app can check for the presence of certain system libraries or specific versions of an operating system that are only available on certain emulators. Finally, apps can also detect emulators by looking for signature patterns in the device’s processor.
Emulators tend to have certain characteristics that distinguish them from real devices and these characteristics can be detected by looking for specific patterns in the processor. In summary, apps can detect emulators by looking for certain hardware, software, and processor characteristics that are unique to emulators and not present in real devices. This helps to protect apps from being run on emulators, which can be used to cheat or bypass in-app purchases and other security measures.
What is simulator vs emulator in mobile testing?
Simulator vs Emulator in mobile testing refers to two different methods of testing an app or website on a mobile device. A simulator is a software application that mimics the behavior of a physical device, while an emulator is a hardware device that emulates the features and functions of a different device. Simulators are used to test the behavior of an app or website on a particular device or operating system.
