  * <p>
  *   These tests mock the {@link TopWinnerStatsChannelHolder#getWinners()} and {@link TeamStatsChannelHolder#getTeamStats()} methods to return pre-defined input and then set up a sample WebSocket client to listen to messages sent by the server. Each message received is placed into a {@link java.util.concurrent.BlockingQueue} so that message content can be asserted once the expected number of messages have been received.
