What Is Mobile App Testing?

Mobile testing for applications is the process by which mobile apps are tested on devices for functionality, usability, and consistency to ensure flawless user experiences. Mobile app testing can be done either manually or with automation.

Mobile App Testing in 2022

In 2022, there are 6.65 billion smartphone users worldwide, which is 86% of the global population. Smartphones are not just a booming industry, but also an essential part of our daily lives. This means mobile testing should be an integral part of a development strategy to stay in the competitive environment. Mobile testing ensures your apps and smartphones are secure, reliable, and user-friendly.

Set up your mobile apps for success and update your test coverage with this blueprint for strategic testing.

What Are the Types of Mobile Testing?

There are three main types of mobile device testing.


App functionality tests include:

  • Business flows.
  • UI testing (e.g., landscape/portrait, languages).
  • Cross-platform coverage.

Real Environment

Real environment condition testing includes:

  • Network conditions.
  • Interruptions (e.g., calls, text messages).
  • Background/foreground.
  • Gestures (e.g., force touch).

For real environment condition testing, it’s especially important to test on real devices instead of simulators.

Non-functional testing includes:

  • Security.
  • Accessibility.
  • Performance and availability.
  • API testing.

There are different approaches you can take to these mobile testing types. This includes manual testing, automated testing, and continuous testing.

Device Testing: Which Ones? How Many?

What combination of devices should you be testing against right now?  

It's a common question! The answer varies depending on your users, your location, and how risk averse you are. 

Testing one one or two devices is not enough. Testing on all devices is too much. Here are three considerations for determining the right devices.

Balance Data & Analysis

Combine data in this free test coverage guide sharing the devices you should be testing (by country) with your own analysis and risk assessment to decide how many devices (how much test coverage) you need to address a majority of your target users.

Map Coverage Against Your Pipeline

Map coverage needs to your test pipeline or apply to your test pyramid. Consider virtual devices for earlier phases of testing. Use real devices in later phases.

Optimize Your Lab Configuration

Consider your test data parameters (like number of tests, test duration, and required execution time). You may need to add devices or test in parallel in order complete all your tests within your cycle. 

How Is Mobile Device Testing Different From Web Testing?

Mobile testing is different from web testing in complexity.

Mobile apps usually have more users and need to work on a broader range of devices — with more communication. This increases testing complexity. While web apps are increasingly used on mobile devices, testing them is not quite as complex.
