Mobile app testing continues to gain importance as people embrace digital transformation. As a result, it’s important to understand what it is, what it involves, and why it’s an important practice in app development. Let’s dive in and thoroughly explore mobile testing, including types, techniques, challenges, and best practices.

What Is Mobile App Testing?

Mobile app testing involves testing mobile apps developed for mobile devices for their functionality, usability, and stability. It’s important to test apps before releasing them into the market to ensure they’re not only functional but stable, secure, and consistent. During the process, the application is also tested for various other aspects such as UI (user interface), performance, security, and vulnerability.

Methods of App Testing

App testing can be manual or automated using virtual emulators. Developers have realized that automated testing, such as virtual iOS testing, is more viable and produces better results with fewer errors. Automated testing also helps:

  • Run parallel tests on multiple devices
  • Get enhanced test coverage
  • Reuse tests
  • Achieve better testing ROI

Types of Mobile Apps

Three types of mobile applications undergo testing before release:

● Native Apps (Android/iOS apps): Apps that are developed for particular platforms or operating systems such as Android, Windows, iOS.
● Web Apps: These apps are similar to native apps, except that they can be used through a mobile device or a web browser. They largely depend on the device’s browser for functionality.
● Hybrid Apps: These are apps that combine both native and web-based apps. They’re more complicated to test, and lack the power and speed or native or web-based apps.

Why Is Mobile App Testing Important?

In the current fast-paced app development, testing apps across various operating systems and mobile devices is vital to check for compatibility, usability, security, and consistency. For example, virtual iOS testing can help improve the performance of an iOS-based app and even get insights to change its functionality to Hybrid. App testing helps to build applications that are accessible and scalable across multiple platforms.

Key Challenges That Mobile App Testing Addresses

Here are some of the critical challenges that mobile app testing tries to address:
● Downloadable: The apple must be downloadable (obtainable) for a platform or various platforms like AppStore, Microsoft Store, or Google Store.
● Diversity in platforms: Is it a native, Hybrid, or web-based application. This diversity must come out clear since each OS has particular limitations.
● Device availability: The ever-growing list of devices and OSs creates a challenge or establishes the right app device access. This can become a greater challenge if testers are in different regions.
● Mobile network operators. Knowing if the app can integrate well with the over 400 mobile network operators worldwide is vital. Examples include CDMA, GSM, FOMA, and TD-SCDMA.
● Scripting: A single script never functions effectively on one device. This variety of devices challenges test script execution.
● Compatibility: Testing must reveal apps’ compatibility across devices, and operating systems is a real challenge, including establishing compatibility with screen resolutions and sizes.

Types of Mobile App Testing

Here are some key types of mobile app testing:
● Functional Testing: Are the app’s functions working correctly or not.
● Compatibility Testing: Is the app working seamlessly in different networks, devices, operating systems, and internal hardware (specifications or requirements).
● Usability Testing: Is the app user-friendly in terms of use, UI, and intuitiveness?
● Performance Testing: How does the app behave or perform under a certain load.
● Security Testing: Security of the user’s personal data is important as the test reveals the app’s behavior under different device permission requests.
Other key types of testing are Installation, Exploratory, Automated, Storage, Interrupt, and more.


The goal of app testing is to reveal and act on the app’s overall functionality before releasing it to the market. This is also important to ensure that the app gives the intended user experience with no functionality issues and security loopholes.
