Device Farm


Device farms are essential tools for simulating the testing process of iOS and Android applications across multiple device platforms. By leveraging some of the best device farms for testing, you can significantly reduce labor costs and time required, thus achieving greater test coverage and streamlining your DevOps mobile pipeline.

In recent times, the range of mobile devices has expanded considerably. Devices now come with different features, operating systems, screen sizes, and more. Therefore, it’s crucial to ensure your applications work flawlessly on every possible device a user might employ.

With the plethora of new versions of Android and iOS devices, manual testing can quickly become expensive and labor-intensive. This has led to the development of platforms that allow simulated manual testing on a broad range of devices, all in one place.

What are Device Farms?

When the device fleet began to grow, Nokia initiated a project to make testers' lives easier by allowing them to run applications on rented devices remotely. However, this approach couldn't scale to the extent of today's mobile variations.

The OS itself now provides tools to simulate user actions on applications, enabling testers to write scripts that can be executed on developer-mode mobile phones. These scripts mimic user actions on devices.

DevOps tools have been developed to automatically build and run these scripts on thousands of mobile devices in remote cloud labs. A fleet of such devices with different variations is called a device farm.

Benefits of Mobile App Testing on Device Farms

Testing mobile applications on multiple devices at scale can be expensive and time-consuming. Device farms offer a solution by providing access to thousands of devices with different configurations. Here are some key benefits:

  • Access to a wide variety of devices with different OS platforms, screen orientations, display sizes, memory, networks, etc.
  • Reduced maintenance and infrastructure costs.
  • Parallel testing capabilities, saving significant time.
  • Secure, cloud-based environments accessible from anywhere.
  • Detailed reports in the form of graphs, video recordings, screenshots, etc.
  • Easier bug detection and fixing.
  • Integration with CI/CD pipelines, enhancing collaboration.

Best Mobile Device Farms for Testing

Device farms use various scripts to simulate actions such as gestures, button presses, and touches. The main difference lies in the subsystems used to execute these scripts. Popular subsystems include Espresso, Appium, Calabash, UI Automator, Robotium, XCTest, etc. Here, we discuss a mix of free and professional device farms and test labs.


RobotQA is a cloud-based, no-code or appium based test automation platform that allows parallel automated or manual tests on real devices hosted in the cloud. It supports managing test cases, eliminating the need for infrastructure setup.
