Both emulators and simulators serve the same purpose – they both allow you to conduct tests on your computer. Popular programming tools, such as the Android Studio IDE and the xCode development environment, already provide them. Virtual devices are great for testing fundamental situations since they provide quick availability without the need to stand in line at the Apple shop to get your hands on the latest iPhone or iPad model.
Simulators imitate software, but emulators imitate both software and hardware, as the name implies. Simulators are popular for iOS devices, whilst emulators are more popular for Android devices.
This article will help you if you are:
- a software developer who builds Android or iOS apps,
- a QA engineer who wants to make sure that the quality of the app built meets your client’s requirements, or
- a tech Practitioner or Analyst who would like to upgrade their gadget collection,
App testing platforms have become an inevitable part of iOS & Android devices. It is the balance between expense and risk that determines whether or not to test on real devices rather than on virtual ones. In a nutshell, genuine devices are more expensive to test, but they can make the difference between having 80 percent confidence and having 90 percent confidence in specific applications. Virtual devices can provide adequate coverage in terms of functionality and user interface testing for the majority of applications. Due to the fact that you may configure the virtual device with whatever flavor and configuration you choose, virtual devices are also less expensive to test. However, app testing is becoming more advanced, taking into account the many Android and iOS devices available in the market. Nowadays, the usage varies depending on business requirements.
Headspin helps you provide the systematic approach as an AI expert that guides the best functions about Emulators and Real Devices to enhance productivity and efficiency. Most tech companies rely on emulators to run their test cases and obtain results. Nonetheless, emulators and real-time devices have their pros and cons, which creates barriers to the process.
Using Real Devices versus Emulators
Emulator
Either hardware or software systems can be emulated by a piece of software that functions in the same way as the genuine device. To test their apps in a digital environment, developers frequently utilize iOS and Android emulators that run on a computer’s screen.
Emulators can be divided into three categories:
The device emulators replace the actual hardware and replicate the operation of genuine smartphones or tablets.
Browser emulators are used for replicating a mobile browser experience. Operating system emulators that operate on mobile devices are also used.
Pros for Emulators
- Emulators are virtual machines created on computers to replicate a few scenarios that restrict better performance.
- Emulators mimic the software and hardware, which wouldn’t be the best solution if you are looking for a genuine response.
- There wouldn’t be any translation process concerning real devices other than those built-in ones.
- An emulator fails to recreate such scenarios to give you the best results.
Real Device
Although actual devices are not a panacea, they are the most effective method to grasp the user experience genuinely. Although they are expensive and time-consuming to obtain, testing on real devices is the most effective way to understand the user experience truly. A physical device is the best way to evaluate the app’s interaction with its user than by putting it on a real device and handing it over to beta testers.
There are no false positives or negatives to be concerned about, only actual findings and a live network.
It is possible to see any performance difficulties relating to the device or the surroundings; all real-life circumstances are taken into consideration, including anything from network failures to diverse weather conditions to hardware issues.
Pros for Real Devices
- Real-device app testing will help you identify numerous bugs that limit the app’s performance that appears in real-time when several users are using the app in distinct ways.
- App testing in devices helps analyze how the app responds to various devices with limited storage space, hardware features, functionality, how the already existing bugs interpret the newly installed app, etc.
- Real device app testing could be much faster than emulators since emulators use a binary translation technique.
- The targeted customers are more likely to use the app built on a real device. Several third-party software is involved that regulate the functionality of an android/ iOS device.
Cons for Both Real Devices and Emulators
- Real device app testing could be time-consuming and could lead to complete failure, as it might create numerous bugs on both manual and automation test scenarios; the same goes with emulators.
- It would be impossible to cover all the Android/iOS devices launched, and emulators are equally unreliable in this matter. Hence both real devices and emulators wouldn’t be able to give you the results expected.
What to Look For in an Emulator
An emulator is used mainly by game testers and developers. The key benefit is that you can have access to the keyboard and mouse while you test. Often wondered what the features to look for while you choose an emulator for app testing are? To learn more, check the guidelines below and see if these are available on your choice of emulators:
- Unique features available in the particular emulator
- Reliability
- Device compatibility and interface
- Overall experience and user-reviews
- Multitasking functionality
- Open-source or paid
How to Use a Real Device for App Testing
For instance, more than half of the population worldwide uses apps on real devices. For a QA engineer, it is crucial to test the app and ensure its performance and responsiveness before the official launch. App testing on real devices can involve testing methodologies like regression testing, compatibility testing, black box testing, functional testing, user acceptance testing, and many more.
App testing platforms such as HeadSpin have a global device infrastructure of thousands of real, SIM-enabled devices around the world that use device cloud methodology to test an unlimited number of devices that can be accessed from any location, thereby eliminating the need for emulators or the costly and time-consuming maintenance of a collection of costly devices. All you need to run tests using HeadSpin is your application or website, the necessary hardware and software specifications, and features. Once the app to be tested is chosen, after certain mandatory checks and settings, the app will be connected to the devices after the certainty process begins.
Tips for Testing Considering Software Development Life Cycle
Depending on which stage of the software development life cycle (SDLC) you are in, your test preferences vary. As a developer or a software tester, you should be well aware of your client’s requirements and expectations from the app, the targeted users, etc., to confirm whether you should test your app on a real device, an emulator, or a device cloud platform. The app’s logical, structural, and user interface sectors can be tested by combining real devices and emulators. App testing platforms like HeadSpin come in handy. You have to test the apps against numerous devices, operating systems, and extended versions and be accessed from one location.
When Should You be Using One Type Over the Other?
It would be ideal to use an emulator for UI testing scenarios to check if the display, the buttons, and the clickable features are working. Use a real device to test the overall functionality and turnaround time (TAT), and device cloud testing platforms like HeadSpin for humongous testing processes beyond your skills and capabilities.

Why Is It Important to Test on Both Types of Devices Before Release?
A software app development, or any software development process for that matter, can be time-consuming and costly. It consumes a lot of money, time and effort, during the entire development cycle. Thanks to the latest software testing methodologies testing processes can be performed as and when the features are developed, rather than testing the product as a whole. Nonetheless, testing could be complicated, and even after resolving the bugs, there could be compatibility issues, or more bugs could arise once you fix the existing ones.
When it comes to delivering findings, there are times when the testers must work under strict time constraints. When purchasing the whole equipment is not viable, the situation becomes much more difficult. In such circumstances, emulators and simulators might come in handy. The tester, on the other hand, is given the opportunity to test the complete device in a real-time scenario while using a real-world gadget. As a result, user-friendly properties may be clearly tested through the usage of real-world devices. In a similar vein, in order to report on tests such as if it is beneficial when walking, an actual gadget must be used in the field.
Choosing which device to utilize for testing can be difficult at times for the tester, especially when there are several options. On such an occasion, emulators and simulators can be employed. In reality, because it is open-source software, an emulator or a simulator may be obtained with relative ease. Emulators and simulators, however, are unable to create information for the shade resolution of the display in real time.
Even if performance tests employ an emulator or a simulation, this is not totally accurate when it comes to actual performance. The majority of the time, the performance of emulators is noticeably slower. The only report that can be believed from a performance standpoint is the real device-based report.
Experts in Quality Assurance (QA) should be hired.
When it comes to memory, it is true that the available memory of the emulator/simulator is far greater than the accessible memory of the real devices. For individuals who take these findings into consideration, it can occasionally lead to a state of bewilderment. This is an instance where it is necessary to rely on the genuine device validation report.
If you are an entrepreneur, this could directly impact your business. As a developer or a tester, leaving a lot of unknown bugs and launching the product in the market destroys your reputation. Hence, one must use all kinds of affordable testing methodologies to deliver out-of-the-world products and services.
Bottom Line
As one of the most reliable app testing platforms, Headspin removes all the necessary bugs that could arise after release. This can be achieved by testing the app on multiple devices, operating systems, and platforms, testing the GPS conditions, connectivity, and app security issues, leaving no room for errors. This will bring the best ROI, earning you guaranteed customer satisfaction and amplifying the annual turnover.
The number of people who are using your mobile app on an emulator is zero, according to our data. As a result, real-world testing is required since simulators simply cannot address all of the concerns that may arise during a real-world user experience. Things as simple as battery usage, compatibility with other applications on the phone, or even a search bar that is cumbersome to press might cause your clients to go elsewhere for a solution. Emulators, on the other hand, are less expensive and can give you useful analytic results on the testing that has been carried out.
At the end of the day, it appears that combining the two ways and supplementing them with a device cloud for testing is the most effective method of proceeding.
