The Economics of Device Farms: Saving Costs in App Testing

5 September 2023

Apps have become an integral part of our lives transforming the way we do our day-to-day activities. From e-commerce and productivity to social media and entertainment, there’s an app for almost everything. However, the development and testing of these applications can be a daunting task for developers and businesses alike. And, with the wide range of devices, versions, browsers, and operating systems, testing the app across all of them can be a difficult and costly affair. One innovative solution to streamline the app testing process while saving costs is incorporating device farms.

Device farm serves as a comprehensive solution to simplify the testing process. It is a Cloud-based service that provides access to a vast array of real devices and browsers for testing. This approach offers scalability, flexibility, and cost-efficiency, making it an effective choice for organizations of all sizes. In this article we’ll explore the economics behind device farms and how they can help companies optimize their testing efforts.

What is a Device Farm?

Device farm, a Cloud-based service, is a collection of real mobile devices hosted in a controlled environment. These devices represent a wide range of manufacturers, models, and operating system versions. Testing teams can remotely access these devices to run their apps and test them for functionality, compatibility, and performance.

Device farms are equipped with automation tools that allow testers to run scripts and simulate real user interactions across multiple devices simultaneously. This not only saves time but also ensures consistent and comprehensive testing coverage.

The Economics of Device Farms

Incorporating device farms offers the following benefits to organizations and saves considerable time and cost.

Reduced Hardware Costs

Maintaining an in-house inventory of mobile devices for testing purposes can be expensive. Device farms eliminate the need for companies to purchase and maintain a diverse range of devices, saving on hardware costs.

Time Efficiency

Automation tools in device farms significantly reduce the time required for testing. Developers can simultaneously test their apps on numerous devices, speeding up the development cycle and reducing cost.

Improved Testing Coverage

With access to a wide variety of devices, device farms help ensure comprehensive testing coverage. This reduces the risk of app crashes and compatibility issues on different devices, saving money on post-release bug fixes and customer support.


Device farms offer scalability, allowing companies to scale their testing efforts up or down as needed. This flexibility prevents over investing in testing infrastructure during quiet periods and ensures readiness when demand peaks.

Enhanced Productivity

Testers can focus on creating and optimizing test scripts rather than performing manual tests on individual devices. This enhances productivity and allows testing teams to spend more time identifying critical issues.

Quick Bug Identification

Automated testing in device farms quickly identifies and reports bugs, enabling developers to fix issues earlier in the development cycle. This reduces the cost of addressing bugs post-release, which can be significantly higher.

Competitive Advantage

Apps that undergo thorough testing and work seamlessly on a variety of devices have a competitive edge. Positive user experiences lead to higher user retention rates, more downloads, and increased revenue.

Choosing the Right Device Farm

When considering the adoption of a device farm for app testing, companies should evaluate their specific needs, budget, and expected testing volume. Several third-party device farm providers offer various pricing models, including pay-as-you-go and subscription-based options. The choice of device farm should be made by considering various parameters, some of which are discussed below.

Key Factors to Consider When Choosing a Device Farm

Choosing the right device farm is a crucial decision in the mobile app development process. A well-selected device farm can streamline testing, enhance app quality, and ultimately lead to a more successful app launch. Here are some of the key considerations to make while choosing a device farm.

Device Coverage

The primary purpose of a device farm is to ensure comprehensive testing across various devices and platforms. When selecting a device farm, consider the device coverage it offers. Ensure that it includes a diverse range of devices with varying operating systems, screen sizes, and resolutions.

Operating System Versions

In addition to device diversity, it’s essential to check whether the device farm provides access to different operating system versions. Mobile operating systems evolve rapidly, and users may have older versions on their devices. Ensuring compatibility with a wide range of OS versions is critical to reaching a broad audience.

Accessibility to Custom Device

An app may require testing on specific devices or configurations unique to the user base. Some device farms allow us to upload custom devices or configurations for testing. If your app targets a niche audience or relies on specialized hardware, this feature can be invaluable.

Test Automation Support

Efficiency is key in app development, and automation can significantly accelerate the testing process. Look for a device farm that supports test automation frameworks and integrations with popular testing tools. Automation capabilities can save time and resources while improving testing accuracy.

Performance Testing

Mobile app performance is critical for user satisfaction. Check if the device farm offers performance testing capabilities. This includes load testing, stress testing, and measuring how your app performs under different network conditions.

Security and Data Privacy

App security is a top concern, and when using a device farm. Ensure that the chosen device farm has robust security measures in place, including data encryption, access controls, and compliance with industry standards and regulations.


Device farm pricing structures vary, and it’s essential to choose one that aligns with your budget requirements.

Reporting and Analytics

Comprehensive reporting and analytics tools can provide valuable insights into the app’s performance across different devices and configurations. Look for a device farm that offers detailed reports and analytics to help you identify and prioritize issues efficiently.


The economics of device farms for app testing are compelling. They offer cost savings, improved testing efficiency, and enhanced testing coverage. For businesses looking to develop and maintain high-quality mobile applications while staying competitive in the market, device farms represent a strategic investment. By leveraging the power of device farms, companies can ensure their apps meet the highest standards of performance, compatibility, and functionality, ultimately leading to satisfied end-users and improved ROI metrics.
