10 Advantages of Using Real Device for Web and Mobile App Testing


What are some good practices for mobile app testing? Simulators and real devices may both be used for app testing. Simulators are used by certain developers and mobile app development businesses, while real devices are used by others. Actual devices should be used for testing since they provide a realistic environment while also ensuring that the software offered is of good quality.

It might seem anachronistic to perform anything directly on actual, bare-metal hardware, whether running a server or testing software, in our current era of virtualized, software-defined everything. Virtual environments are more adaptable, fluid, and scalable than those based on physical hardware. Let’s look at some reasons why real-device testing is preferable.

What is the definition of a mobile simulator?

A simulator is a tool or software program that mimics the behavior of a real-world environment or equipment. The following are some of the primary advantages of using a mobile simulator: Simulators are practical and simple to use. They are regarded as a low-cost means of evaluating the app. The majority of the simulators are available for free download. Thus, there will not be a requirement to buy a simulator online.

App installation is quicker on simulators, making it easier to test the app on many simulators. There are very few odds of a sluggish network. The simulator makes it easier to test the software. On a simulator, the testers have full access to the local storage. It clarifies how the app interacts with the device’s local storage.

Why is it advantageous to utilize real devices?

Despite the benefits of simulators, many developers recognize that testing the app on actual (genuine) devices is the most reliable method. Because simulators have some restrictions, it is a good idea to test the app on actual mobile devices. Simulators are useful during the early stages of development since they resemble the real testing environment. When it comes to thorough app testing, actual devices may be used.

It may be costly to test applications on actual devices since you would have to purchase them. With new goods and upgrades being released on a daily basis, you may need to update your devices to keep up with the market and industry trends. If you want to provide a better user experience, consider investing in the newest gadget versions.

When should you use real-time device testing?

Using real-device testing at the end of the delivery cycle throughout development and system testing is the simplest solution. That way, you receive the accuracy of real-device test findings just before release, but you don’t have to worry about real-device testing slowing down your delivery pipeline in the early stages. And, assuming your app has passed all previous tests, any defects discovered during real-device testing will most likely be trivial and easy to fix.

However, there are several circumstances in which real-device testing should be done first. If your app is heavily reliant on the hardware of the smartphone, it’s probably worth the additional time and effort to do real-device testing as soon as possible. It’s best to spot show-stopping hardware-related difficulties early on, so you don’t have to rewrite a lot of code to remedy them.

To put it another way, in case your application is heavily reliant on hardware capabilities inside a device, do real-device testing early and frequently (but there’s no reason why you can’t also utilize simulators and emulators). However, if it isn’t, you’ll probably be able to get away with real-device testing in the end.

Real device vs. Virtual devices in mobile and web testing

The purpose of virtual mobile testing devices is to mimic and re-implement the software environment of real-world smartphones. Despite their similar resemblance to genuine gadgets, these solutions are not the same. Emulators do a good job of simulating the testing environment of actual devices, but they aren’t perfect.

Using an emulator, though, you may still see a reflection of the genuine device under perfect settings. Because real devices have a variety of external circumstances, they can most accurately predict an app’s performance.

Hidden elements such as the device’s age, temperature, and age, as well as the number of other applications operating on the device and the humidity surrounding it, may all affect app performance. Real gadgets, on the other hand, have certain drawbacks of their own. It’s not simple to debug a smartphone using a genuine device. In terms of debugging, emulators outperform genuine devices.

Simulators, on the other hand, surpass emulators and genuine devices due to their speed. Furthermore, as compared to both emulators and actual devices, simulators are more effective for testing simple apps. Simulators, on the other hand, are less expensive, making them more accessible to more testers. Despite the relative benefits of virtual mobile testing devices, there are certain features that simulators and emulators will never be able to replicate. Push-up alerts, incoming calls, the device’s battery/camera, and other features are incredibly tough to replicate effectively.

What are the advantages of using real devices for web and mobile app testing?

You should test the user interaction before releasing the app. On the simulator, using a mouse and keyboard is quite different than using a finger on a mobile device. It is recommended that you invest in genuine devices for app testing. For more detailed information, continue to read on:

1. Competence in carrying out the tests in real-world conditions

The actual gadgets are controlled with fingertips, simulating real-world operation. As a result, it aids in the testing of applications in a natural setting, i.e., the app will be utilized in a variety of settings and environments. As a result, all real-world factors are taken into account, including network outages, weather conditions, and device malfunctions.

2. Cross-platform testing

Real-world device testing of the app on many platforms, operating systems, and OS versions aids in comparing and analyzing the app’s performance in various situations. You won’t have to worry about false positives or negatives since accurate device testing yields real findings, revealing all of the device’s or environment’s performance flaws.

3. App usability

The QA team may use real device testing to test the app’s usability concerns. The testers will be able to create the test documentation and execute it on actual devices. Because the mobile device market is so fragmented, testers must run their tests on a variety of instruments and browsers in order to give a satisfying user experience.

Accurate device testing confirms the app’s appearance and interface, as well as if the image is visible in both day and night situations. As a result, actual device testing aids in determining the app’s usability and ensuring the end-users complete happiness.

4. Extensive performance evaluation

In real-world circumstances, accurate device testing helps assess the reaction speed and availability of a mobile application’s critical transactions. It allows the tester to evaluate the app’s back-end and front-end performance on actual mobile devices under a variety of network situations.

5. Reliability

Real-world testing is more trustworthy than testing on emulators or simulators. The possibility of inconsistent test findings is eliminated with accurate device testing. When compared to emulators and simulations, it provides better accuracy. Because the mobile OS is not executed on a real device, emulation testing has a number of drawbacks.

Similarly, a simulator approximates the behavior of the real device but does not provide a genuine duplicate of the mobile operating system. As a result, actual devices are often the most effective platform for app testing.

6. Memory and storage requirements must be tested

Memory, camera, and CPU are just a few of the hardware requirements for apps. On a device with less memory, it tends to crash or operate slowly (RAM). It can, however, operate well on instruments with more memory. Real-world device testing aids in determining the app’s hardware requirements.

7. Testing

You can test your app against a variety of features and sensors that your app relies heavily on in order to perform accurate device testing. If your program includes functionalities that are reliant on certain sensor kinds, this is critical. Testing on a real device permits you to see how the app will react when it interacts with mobile features such as GPS, camera, Bluetooth, and fingerprint sensor.

8. Rendering accuracy up to each pixel

Real-world device testing allows you to evaluate the app’s brightness and screen resolution in a variety of lighting settings. It also helps in thoroughly verifying the precision with which the software produces each pixel.

9. End-user actions should be recreated

The tester can recreate the actions that users take while using the app using real devices. As a result, it aids in validating the applications’ performance in the face of hardware interruptions like SMS, calls, push notifications, and so on.

10. Wider coverage

You may create suitable test cases with realistic device testing to cover the greatest number of test scenarios necessary, depending on the current release. For better test coverage, establish a list of real devices before starting the test procedure.

Testing your mobile application has a big influence on its performance and success. It improves a mobile app’s performance, capabilities, and quality while confirming its main operations.


These programs will not work at their best without significant testing. Mobile app testing is more difficult since it requires managing various specs, optimizing notification handling, and testing synchronization across many platforms. From a pool of 3000+ real devices, test and debug your app for responsiveness and compatibility. Testers have learned how to guarantee that mobile apps run well, whether they are native or hybrid, thanks to their years of expertise. An in-depth understanding of numerous testing techniques enables service providers to uncover hidden faults in various software components and give the best solution for your company.
