You can use a REST API call to check if devices with the desired specifications are available before actually attempting to initialize the Appium driver. This way, you avoid a driver initialization error in case no such devices available for the test to start. This error would show up in Perfecto's Report Library as a blocked test.
The following example is based on the Get Device List API. It gets the count of all available devices in the specified cloud that are in a Connected state and not in use. The REST API returns an XML response that includes the list of available devices of a specific OS, OS version, and model. The list is based on the specific cloud user running the test, authenticated with the Perfecto security token.
