This document discusses how to set up remote testing capabilities for the Rant Cell Pro app using Google Cloud Messaging (GCM). It involves: 1. Configuring a project in the Google Developer Console to enable GCM and generate server API keys. 2. Having the Rant Cell app register with GCM to receive a registration ID when launched. 3. The server sending command messages using GCM and the registration ID to trigger tests on the app, which will then run the configured tests. 4. Providing a tracking feature on the website to monitor test status and results from devices in real-time.
