* @file transport/test_transport_api_disconnect.c
* @brief base test case for transport implementations
*
- * This test case serves as a base for tcp, udp, and udp-nat
- * transport test cases. Based on the executable being run
- * the correct test case will be performed. Conservation of
- * C code apparently.
+ * This test case tests disconnect notifications in peer shutdown
