+/**
+ * @file binlog_failover.cpp binlog_failover Test of failover scenarion for binlog router
+ *
+ * - setup following configuration:
+ *   - one master
+ *   - two maxscale binlog machines
+ *   - two slaves connected to each maxscale binlog mashine
+ * - put some date via master
+ * - block master
+ * - stop all Maxscale machines with STOP SLAVE command
+ * - check which Maxscale machine contains most recent data (let's call this machine 'most_recent_maxscale')
+ * - use CHANGE MASETER on the second Maxscale machine to point it to the Maxscale machine from the previous step ('most_recent_maxscale')
+ * - wait until second Maxscale is in sync with 'most_recent_maxscale' (use SHOW MASTER STATUS)
+ * - select new master (HOW??)
+ * - set all Maxscale machines to be a slaves of new master
