21 * @file transport/test_transport_api_manipulation_recv_tcp.c
22 * @brief base test case for transport traffic manipulation implementation
24 * This test case will setup 2 peers and connect them, the first message
25 * will be sent without manipulation, then a receive delay of 1 second will
26 * be configured and 2 more message will be sent. Time will be measured
28 * In addition the distance on receiver side will be manipulated to be 10
31 #include "gnunet_transport_service.h"
32 #include "transport-testing.h"
35 * How long until we give up on transmitting the message?
