21 * @file transport/test_transport_api_unreliability_constant.c
22 * @brief test case for transports; ensures messages get
23 * through, regardless of order, constant packet size
25 * This test case serves as a base for unreliable
26 * transport test cases to check that the transports
27 * achieve reliable message delivery.
