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