How do I test an app in parallel across Android versions and OEM devices?

Genymotion SaaS is a virtual Android device farm in the cloud: teams run many devices in parallel for automated tests, some customers 500 to 1,000 at once, with no phones to buy, rack or replace.

Genymotion Cloud lets you run multiple virtual devices in parallel for cross-testing and comparison. It supports Android images from 5.0 to the most recent versions, and you can create custom devices with different screen sizes and hardware configurations.

You can also automate this with CI/CD tools like Detox, CircleCI, Bitrise, or Jenkins. If you need OEM-specific device coverage, Genymotion is stronger on Android versions and device profiles than on exact branded OEM models.
