Mobile Testing with Simulators/Emulators vs Real Devices

Well, only a few can say that the emulator and simulator can be beaten in one group. However, real device testing does what implies - it tests the application when they run a user's smartphone.

Let's look at the deeper category.

Real device cellular testing requires the actual use of smartphones. But the emulator and simulator are based on the concept of virtual testing. Virtual testing involves testing software that provides the same function as provided by real telephone.

To test the mobile application, the emulator is a desktop application that mimics hardware and OS applications that must be tested. Simulator does not mimic hardware / OS, but imitate the basic behavior of a device. While simulators are usually simpler than emulators, they are useless like emulators. Testing real device checks the functionality of cellular applications as a whole and ensures appropriate application work.

The emulator provides better results compared to simulators because it can be used to test certain situations or cases, and can also mimic multiple devices. Emulators are often used more because they are relatively cheaper - especially when compared to real devices.

Emulator / simulator vs real device

Let's try to compare what provides better benefits in the following scenario:

Situation Based Scenario: In situation-based scenarios, buying required cellular devices may be difficult - when using emulators / simulators can take care of needs. This means, not all scenarios can be tested on the simulator / emulator - this is only possible if the test is done on the cellphone.

The ease of use: Emulator or simulator makes testing a number of applications on some mobile devices available today is much easier, but they lose the aspects of UI and UX applications, including display colors and brightness.

Ease of access scenarios: Testing on reliable cellular devices - However, testing on emulators and simulators makes it easier because it only requires URL for the application.

Validation of Battery Scenarios: Mobile devices can do this test as needed while emulators and simulators usually cannot mimic the problems associated with the battery.

Validating Performance: This is a very important part of testing cellular applications. Testing application performance on mobile devices usually provides more accurate results than when tested on emulators or simulators.

Which is a better choice?

While the emulator and simulator look like a big alternative to test the application, because it has a variety of real devices also contributing the costs involved.

However, they have problems that can produce false positive and negative results, which will definitely have a negative impact on the business ROI.

Another disadvantage of the emulator / simulator is that how many of their features are possible for real applications, emulators / simulators may still do not cover all features / scenarios and the results obtained may not be as accurate we want them.

Testing real devices won the challenge of one of the two. With an efficient testing process, real devices can validate for any possible scenario with almost 100% accuracy.

However, having the three options have its own benefits, and can be used according to needs, helping organizations fulfill their goals.
