7 Top Device Farms to test your iOS and Android applications
Device farms are used to simulate the testing process of iOS and Android applications on multiple device platforms. Subsequently, you can cut labor costs and time required by using some of the best device farms for testing. Hence, it helps you achieve greater test coverage and eases your DevOps mobile pipeline.
In recent times, there has been a gradual increase in the range of mobile devices. We see devices with different features, OS, screen sizes, etc. Therefore, it’s natural that we need to put more effort into testing our applications on each of these devices. We want our applications to work flawlessly on every possible device the user might use.
With all these new versions of Android and iOS devices available, manual testing will take a toll on your budget and labor hours. Hence, there was a need for a platform that would allow you to perform simulated manual testing on a broad range of devices all in one place.

What are device farms?
When the device fleet rose in earlier times, Nokia started an initiative to make the lives of testers somewhat easier. They would allow them to run their applications on rented devices in a remote-controlled mode. However, we could not scale it to the extent of mobile variations that we have now.
As a further development, now the OS itself could provide tools that would allow testers to simulate user actions on applications. Consequently, they can write scripts that can be executed on mobile phones running in developer modes. These scripts would easily imitate user actions on devices.
Subsequently, they built DevOps tools that automatically build and run these scripts on thousands of mobile devices. These devices would have the target applications on them and run in developer mode.
A fleet of such devices with different variations running on remote cloud labs is called a device farm.
Benefits of mobile app testing on device farms
If you are working at scale, testing your mobile applications on multiple devices becomes really expensive and time-consuming. On device farms, you have access to thousands of devices with different configurations.
You can leverage emulators and simulators to perform your testing. Cloud-based testing also allows you to capture performance issues. Here are some of the most important benefits of using device farms for mobile app testing.
- You have lots of devices with different OS platforms, screen orientations, display sizes, memory, network, etc. It reduces the overall maintenance and infrastructure cost.
- You can perform parallel testing which will save you tons of time.
- Cloud-based environments are usually secure and they can be accessed from anywhere.
- You can get detailed reports in the form of graphs, video recordings, screenshots, etc.
- With the help of all the reports, it becomes easier to spot bugs and fix them.
- You can easily integrate them with your CI/CD pipeline, making collaboration easier.
Best mobile device farms for testing
On a lower level, all the device farms use some kind of special script. This script is launched by the OS to simulate actions like gestures, button presses, touch, etc.
The main difference is the subsystems used by these device farms for executing these scripts. Some of the popular ones are – Espresso, Appium, Calabash, UI Automator, Robotium, XCTest, etc.
In this article, let’s discuss a mix of free and professional device farms and test labs.
This is the most widely used and best mobile device farm for testing currently available in the market. It lets you test concurrently on multiple devices to speed up the execution of your test suites. It also generates logs and videos for extensive debugging.
Some of its core features are –
- A large number of devices with options to choose memory, CPU usage, location, carriers, etc.
