How to Select Devices for Mobile Testing?

This article explores various factors that testers should consider when choosing devices for software testing and recommends WeTest Live Testing as a convenient and efficient solution.

Software testing plays a crucial role in ensuring the quality and functionality of mobile applications. One important aspect of testing is selecting the right mobile devices for comprehensive test coverage. 

Software testing can be done by considering the following aspects:


1. Target Audience

Understand the target audience of the application and determine the devices that are most commonly used by them. This will help prioritize the selection of devices for testing.

2. Market Share

Research the market share of different mobile devices to identify the most popular ones. This will ensure that the application is tested on devices that are widely used by users.

3. Operating System Versions

Consider the different versions of operating systems that the application needs to support. Testers should select devices that cover a wide range of operating system versions to ensure compatibility.

4. Screen Sizes and Resolutions

Test the application on devices with various screen sizes and resolutions to ensure that the user interface is properly displayed and functions correctly.

5. Hardware Features

Consider the hardware features that the application utilizes, such as a camera, GPS, accelerometer, etc. Testers should select devices that have these features to thoroughly test their functionality.

6. Performance and Speed

Test the application on devices with varying performance capabilities to ensure that it performs well under different conditions.

7. Network Connectivity

Test the application on devices with different network connectivity options, such as 3G, 4G, Wi-Fi, etc., to ensure that it functions properly in different network environments.

8. Budget Constraints

Consider the budget constraints of the testing project. Testers should select devices that provide a good balance between coverage and cost.

By considering these aspects, testers can effectively select the devices for testing purposes and ensure comprehensive test coverage for the application.

Experienced Testers Frequently Employ Such Scenarios:


1. Opting for a strategy or method for choosing mobile devices;

2. Identifying presently accessible and popular mobile devices in the market;

3. Discovering which devices frequently lead to issues;

4. Determining the required operating systems and their versions;

5. Assessing the supported types of network connection for the selected devices;

6. Constructing a classification tree of devices suitable for manual and automated testing of the software product and making the appropriate choices;

7. Inquiring with the development team and other stakeholders regarding the suitability of the strategy and the feasibility of acquiring and utilizing the designated devices for mobile testing;

If the approach seems unsuitable, it becomes necessary to reexamine the project and devise an alternative strategy that is more suitable.


Selecting the appropriate mobile devices for software testing is essential to ensure comprehensive test coverage and deliver a high-quality application to users. By considering factors such as target audience, market share, operating system versions, screen sizes, hardware features, performance, network connectivity, and budget constraints, testers can effectively choose the devices for testing purposes.
