You can run tests on real devices on the cloud by creating Runs. To create Runs, you first need to create a Run Configuration. A Run Configuration (or in short "config") specifies the order of tests and other parameters in the Run.
You can also run a Robo Test. A Robo Test analyzes your app and explores it by simulating user behavior. It can help you validate UI issues or discover crashes without creating any Barista Tests.
