AWS Device Farm is an application testing service that lets you improve the quality of your web and mobile apps by testing them across an extensive range of desktop browsers and real mobile devices; without having to provision and manage any testing infrastructure. The service enables you to run your tests concurrently on multiple desktop browsers or real devices to speed up the execution of your test suite, and generates videos and logs to help you quickly identify issues with your app. Test your app in parallel against a massive collection of physical devices in the AWS Cloud. Use one of our built-in frameworks, to test your applications without having to write or maintain test scripts, or use one of our supported automation testing frameworks. Run tests and interact with a large selection of physical devices. Unlike emulators, physical devices give you a more accurate understanding of the way users interact with your app by taking into account factors like memory, CPU usage, location, and modifications made by manufactures and carriers to the firmware and software. We are always adding devices to the fleet. See the device list. Manually reproduce issues and run automated tests in parallel. We collect videos, logs, and performance data so you can dive deep and solve problems quickly.
