For Automated Testing, devices are selected through a collection called a device pool. Some curated device pools are provided automatically, but you can create your own pools, too. During execution, tests will be run against all devices in the specified pool that are compatible with your application and tests. For Remote Access, you select the desired device based on make, model, carrier variant, and operating system version. You can then optionally upload apps and other data as well as configure other device settings. Device Farm then locates an available device matching your request and displays the device’s display in your browser. You can then interact with the device and capture screenshots and video.
