+ * @brief base test case for transport traffic manipulation implementation
+ *
+ * This test case will setup 2 peers and connect them, the first message
+ * will be sent without manipulation, then a receive delay of 1 second will
+ * be configured and 2 more message will be sent. Time will be measured
+ *
+ * In addition the distance on receiver side will be manipulated to be 10
