21 * @file transport/test_transport_api.c
22 * @brief base test case for transport implementations
23 *
24 * This test case serves as a base for tcp, udp, and udp-nat
25 * transport test cases. Based on the executable being run
26 * the correct test case will be performed. Conservation of
27 * C code apparently.
