Mobile App Testing

Software testing has long been an integral part of the development process. However, mobile app testing stands out as the area of software testing that requires the most attention today. Mobile app testing is no longer viewed as a scaled-down browser version of the app. According to research by Statcounter, about 52% of the users prefer using a mobile app over a desktop.

With the mobile industry growing rapidly, any app needs to be compatible across the different versions of iOS and Android devices.

Mobile app testing involves attestation for functionalities, performance, usability, and consistency by running them on virtual mobile app testing platforms. Mobile app testing is performed on three parameters: functionality, real environment, and non-functional aspects.

Functionality testing covers business flow, UI testing, cross-platform coverage, while real environment testing aims for background testing, interruptions, gestures, and testing under different network conditions.

In this article on mobile app testing, we will see how to get started with mobile app testing using Android emulators and iOS simulators.

So, letโ€™s get started!

Need for a virtual mobile app testing platform

QA teams need to perform mobile app testing multiple times before releasing them to production. Procuring a real device to test the features all the time is a costly affair, given the fragmentation of devices and operating systems.

When you release a mobile application, it needs to be compatible with different devices and different versions. The number of mobile devices is 15 billion in 2021 and is expected to reach 18.22 billion by 2025. Performing mobile app testing on 15 billion real devices is almost impossible. The real mobile app testing challenge is maintaining 15 billion devices to do testing.

The magnitude of this problem increases if you want to test your application or website on a mobile browser. Given below is the market share of mobile browsers.

virtual mobile app testing

Most of the browsers update their versions every 15-20 days. So when it comes to mobile app testing, you need to test your web app on different browsers that you want to support and the different browser versions.

Given all these hassles, mobile application testing using emulators and simulators makes testing a breeze for QA teams. App emulators let you execute a program on a device without actually installing it. Simulators, on the other hand, work with native applications. Therefore, knowing the emulator vs simulator difference is important before performing mobile application testing using emulators and simulators.

What is an Emulator in mobile app testing?

A mobile app emulator is a virtual platform that simulates the android device on your computer, making it seamless to perform mobile application testing using emulators. As a result, you can perform Android app testing without the need for a physical device.

What is a Simulator in mobile app testing?

A simulator is a virtual platform that imitates the iOS operating system and runs the application on the selected apple device by taking charge of the computer’s operating system without needing a physical device. Using a simulator allows you to perform iOS app testing or mobile app testing using simulators easily.

The first question that would come to your mind is, โ€œShould I choose an emulator or simulator to test my application?โ€

The answer is to plan your mobile app testing strategy to push yourself to reach your objectives. Both being the virtual platforms have their merits and demerits.

Some developers advise going for the cocktail of tests spread across simulators, emulators, and sometimes for more precise results, a real device too. When it comes to emulator-based testing, developers look at it as a litmus test for the functionalities and features taking shape at the time of development.

Difference between Emulator and Simulator

Emulator and simulator – based mobile app testing is successful and considered one of the smooth methods to evaluate the performance of the mobile apps. However, like every technology, mobile application testing using emulators and simulators have their crests and troughs.

Issues Advantages Disadvantages

Mimics real devices

Simulators/Emulators work as real devices giving the real environment to perform Android app testing and iOS app testing.

May hamper the tester’s confidence on the arrival of the new version of OS.

Easy to Fetch

Simulators/Emulators are usually available for use without any underlying constraints.

Availability of Beta version may remain unavailable for the testing leading to certain restrictions on testing.

Capturing Results

Working on a simulator/emulator works well if a user can take a screenshot of the bug observed while building the app.

The screenshot of the bug observed while building the app may appear differently if the new version of the OS is released.

Internal Storage

Internal Storage and related issues may not appear while working on simulations and emulations.

The internal storage and related issues can easily hamper the mobile app performance as real devices may have certain limitations.

Not the Last Resort

Considering the profuse changes in the device environment, developers tend to resolve most functionality issues.

Mobile application testing using emulators and simulators does not always bring outstanding platters as performance validations may vary with enhancements in the OS.

Apart from the mentioned contrast, certain challenges may exceed the allocated team size and the corresponding budget. Moreover, even if we can work on it, a new challenge may appear where an emulator/simulator may not support the required mobile applications. In such a scenario, we have to pay and play the software patches, which may prove costly to the organization. Listed below are the differences between testing using a real device and testing using an emulator and simulator.

Criteria Real Device Emulator/Simulator

Reliability

Real devices allow you to test features such as the battery, GPS, etc

Virtual testing cannot replicate hardware configurations

Debugging

Debugging using a real device is time-consuming

You can easily debug and track your issues

Cross-Platform Testing

You cannot perform cross-platform testing

It is extremely easy to perform cross-platform testing.

Cost

Costly as you have to buy a lot of devices to test your application

Cheaper as you can test your app or website on all devices using a testing platform like LambdaTest. Check out the LambdaTest pricing page for more details.

What to look for in a mobile app testing tool?

A mobile app testing tool is supposed to make mobile app development easier. But how do you choose the right mobile app testing tool for your team?

The question of what kind of tools to use is difficult enough, but it’s complicated by the fact that the market is fragmented. There are many mobile app testing tools on the market, and each has its own features, target audience, pricing model, and approach. And this is because many different types of teams could benefit from tools that allow mobile application testing using emulators and simulators.

Here are some important aspects/features that should be considered when choosing a toolset for mobile app testing.

  1. Easy upload
  2. Availability of different devices for Android app testing
  3. Availability of devices for iOS app testing.
  4. Real-time debugging options
  5. Native experience
  6. Geolocation testing
  7. Test any environment
  8. Test logs
  9. Issue tracker
  10. Integrations

Choosing the right mobile app testing tool

Mobile app testing is an important part of the overall mobile application development life cycle. Therefore, it is beneficial to choose the right tool for the job.

Tools that allow mobile app testing using simulators and emulators are available in two categories: cloud-based and on-premise. While mobile device cloud testing solutions are gaining popularity for their ease of use and scalability, many organizations still prefer on-premise tools. When it comes to cloud-based mobile app testing solutions, there are many tools to choose from.

LambdaTest is a popular cloud-based cross browser testing tool that offers both real device testing as well as virtual platform testing using emulators and simulators. Apart from the seamless capability to perform mobile application testing using emulators and simulators, there are several reasons why the LambdaTest is among the most recommended mobile app testing tools:
