/**
* <strong>Description</strong>: Back-To-Back WebRTC switch. Three clients:
* A,B,C sets up WebRTC send-recv with audio/video. Switch between following
* scenarios: A<->B, A<->C, B<->C. At least two rounds. <br/>
* <strong>Pipeline(s)</strong>:
* <ul>
* <li>WebRtcEndpoint -> WebRtcEndpoint</li>
* <li>WebRtcEndpoint -> WebRtcEndpoint</li>
* <li>WebRtcEndpoint -> WebRtcEndpoint</li>
* </ul>
* <strong>Pass criteria</strong>:
* <ul>
* <li>Browsers starts before default timeout</li>
* <li>Color received by clients should be green (RGB #008700, video test of
* Chrome)</li>
* </ul>
