10 Mobile App testing best practices

After understanding the importance and challenges of mobile app testing, let’s see what mobile app testing best practices are.

1. Create a detailed test plan

Creating a detailed test plan is essential for successful mobile app testing, as it:

  • Outlines the testing approach, scope, timeline, and test cases, ensuring thorough quality and functionality testing.
  • Assists in identifying the tools, infrastructure, and resources required for testing.
  • Defines each test cycle uniquely, contributing to a robust and well-tested app.
  • It gives the team insight into what needs to be tested and how to mitigate issues during testing.

2. Understand your target audience

To meet users' needs effectively, testers must understand their expectations, demographics, and behaviors. With this understanding, testers can identify the critical features of the app that users want and understand what frustrates them. This knowledge helps testers to craft relevant test cases and simulate the most accurate user scenarios. It also helps to identify valuable insights into areas where the app might be lacking and gives developers the necessary feedback to make the necessary improvements.

3. Know your app

The testers must comprehensively understand the app's goals, requirements, and user scenarios. They need to identify the potential issues that may arise during app usage and test accordingly, using relevant test cases. For instance, if an app is designed to help users track their daily water intake, testers should not only check if the app records the input correctly but also consider scenarios like changing time zones or interruptions during input. 

This detailed understanding ensures that testing is purposeful, with each test case contributing uniquely to enhancing the app's functionality and user experience. Additionally, being familiar with the app helps testers recognize how it interacts with other systems or platforms, including databases, back-end systems, and third-party tools, ensuring seamless integration and performance across the board. 

4. Use automated and manual testing

Both automated and manual testing are essential parts of mobile app testing.  Automated testing helps detect potential issues, offering quick and reliable results without human intervention. Automated testing is ideal for testing the same function repeatedly and continuously (like in regression or load testing), as it eliminates human errors and saves time that you would otherwise spend on repetitive tasks.

On the other hand, manual testing allows testers to navigate and perform complex user flows, identify user interface issues, and execute visual inspections. For example, a manual tester might simulate a user signing up for a new account on a mobile app to ensure that the sign-up process is intuitive and that all user inputs are correctly validated. The best approach is combining automated and manual testing to ensure thorough testing of mobile apps

5. Consider usability and UI testing

Usability testing analyzes the app from a user's perspective, determining whether it is easy to use, such as manually checking if users can easily navigate through a shopping app to find and purchase products without confusion. On the other hand, UI testing analyzes the app in terms of design and user interface, like automatically verifying that all buttons are correctly aligned and responsive across different screen sizes.

With usability testing, testers identify issues related to mobile device compatibility and test scenarios and user flows. Meanwhile, UI testing ensures that the app's interface is functional, user-friendly, and meets the standards of the target audience. It helps testers identify design issues that may interfere with the user experience. Incorporating usability and UI testing in mobile app testing ensures that the app will provide the intended user experience and be adopted by users. A poorly designed and difficult-to-use app may result in negative reviews, a low adoption rate, and a failure.

Pro tip

Effective usability and UI testing involves a combination of automated and manual methods, utilizing diverse tools to encompass various user scenarios. The objective is to guarantee every user experiences a seamless and consistent interface with your web app, regardless of the device or browser used.


6. Other types of testing to consider

In addition to usability and UI testing, mobile app testing encompasses other testing practices that ensure the app works seamlessly. Some of the different types of testing to consider are:

  • Functional testing checks if the app meets the requirements and intended use case.
  • Performance testing ensures the app runs efficiently, testing lag time and speed, resource usage, and scalability.
  • Security testing detects security vulnerabilities and provides user data is secure.
  • Compatibility testing verifies the app works on different platforms, devices, and OS.
  • Localization testing checks if the app functions well under different languages and local contexts.
  • Regression testing ensures changes and features don't create unintended outcomes.

7. Conduct cross-platform testing

With numerous mobile devices and platforms on the market, like Android, iOS, and Windows, cross-platform testing is a critical aspect of the quality assurance process. It verifies that the app functions consistently across various devices, operating systems, and platforms. Cross-platform testing identifies essential compatibility issues such as screen size, image resolution, and aspect ratios and ensures that the app works reliably. Furthermore, it provides the developer with valuable feedback to ensure that the app works perfectly across the targeted user's devices, supporting a seamless experience.

8. Conduct connectivity-related testing

Connectivity-related testing is an essential mobile app testing practice that ensures the app works well in different network conditions. Given the rise of mobile devices and the demand for mobile internet access, connectivity-related testing checks whether the app supports different network speeds, such as 2G, 3G, 4G, and Wi-Fi.
