/**
 * <strong>Description</strong>: WebRTC to HTTP switch. Test KMS is able to
 * dynamically switch many WebRTC flows to a single HTTP endpoint Setup. Two
 * clients WebRTC send-only with audio/video: A,B. One HTTP-EP: H. Switch
 * between following scenarios: A to H, B to H. At least two round.<br/>
 * <strong>Pipeline</strong>:
 * <ul>
 * <li>WebRtcEndpoint -> WebRtcEndpoint (A)</li>
 * <li>WebRtcEndpoint -> WebRtcEndpoint (B)</li>
 * <li>WebRtcEndpoint (A) -> HttpGetEndpoint</li>
 * <li>WebRtcEndpoint (B) -> HttpGetEndpoint</li>
 * </ul>
 * <strong>Pass criteria</strong>:
 * <ul>
 * <li>Browsers starts before default timeout</li>
 * <li>Color received by HttpPlayer should be green (RGB #008700, video test of
 * Chrome)</li>
 * </ul>
