How To Test a Mobile App in Android or iOS – A Guide

Testing is an essential component of the mobile application life cycle. However, because of the effort and time required to complete the entire testing process, it is neglected by developers a lot of the time. It is essential to test a product at every step to make an application that is reliable and can make it enjoyable for users.

According to Statista, there will be more than 230 billion mobile app downloads in 2021, a figure higher than 200 billion in 2019. The market for mobile apps is growing, which is why mobile apps play an essential part in our daily lives. That’s why conducting portable tests is crucial to ensuring company growth. The guide below will explain the process of testing mobile devices, how to perform it, and the challenges you’ll need to master.


What is Mobile Application Testing?

Testing for mobile devices is where applications that run on contemporary mobiles are evaluated for usability, functionality performance, and more.

Testing on mobile devices is crucial to creating a top-quality product distinct from the crowd. Before releasing an app on the marketplace, each company must ensure that it is available to users, reliable, consistent and user-friendly.


What is the reason mobile app testing necessary?

As we can see in the present, the usage of mobile phones is growing every day. New applications are downloaded in response to reviews and ratings each day. Reviews and ratings for applications are dependent on the app’s performance. Therefore, this means that testing the mobile app is crucial. Different mobile phones operate on other operating systems and have various sizes of screens, making testing mobile phones a necessary procedure for software development. The update in the app will entertain the users. New bug fixes for the app ensure that no one uninstalls the app. Testing is crucial for apps to remain in the market.

In our current times, mobile phones have become very popular on the market. We do not wish to switch on our PCs or laptops. Instead, we prefer devices that can effortlessly and perform the job quickly.

This is the reason mobile apps must be tested before release.


How to Do Mobile Testing?

  1. Decide Your Devices

The initial step in your mobile testing strategy must be choosing the correct device to test your mobile application. Make sure you select real devices with different screen resolutions and OS to get accurate test results.

  1. Decide Between Emulators or Simulators

Because mobile testing devices on actual devices can be expensive and time-consuming, users can test using two virtual machines, the simulator and the emulator.

A mobile simulator emulates the operating system designed specifically for mobiles and allows you to run applications not explicitly designed for your OS. Emulators, for instance, an Android mobile emulator, are the same but use the hardware that the mobile’s hardware.

Emulators are more suited to debugging, but binary translation slows them down. Simulators may not be so reliable for debugging. However, they can be quicker since there is no binary translation. There is no way to alter your applications by using emulators. Simulators allow you to create identical environments to the OS of the original device.

So, simulators are more suitable for testing mobile devices, and emulators are better for testing mobile websites. But, the most effective way to get the most precise results is to utilize real instruments instead of virtual ones.

  1. Understand Tools

The next step of your mobile test application strategy is understanding the tools you can use to translate your tests into action. This will help you become more efficient and give you greater confidence when testing.

Although you can create your testing frameworks to increase efficiency, speed up testing and cut down on the cost of maintenance, vendor-based tools let you meet increasing requirements faster and receive more feedback more quickly. Vendor-based agencies already come with features that allow anyone to conduct a test, regardless of their technical expertise.

Setting up and choosing the testing framework you want can be challenging. However, vendors’ tools offer a quicker learning curve, making it simpler to begin by automating. When you use vendor-based tools, it is possible to reach customer support 24/7, which means you can resolve any problem at any moment.

  1. Document Throughout the Entire Process

Documentation is essential to creating the perfect mobile test plan. If you don’t write down your strategy everything from beginning to end, you could waste your time and create issues later on. However small you think it is, it’s helpful to document every decision, as it will aid in training employees and resolving problems.
