  * @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 serves tests disconnect notification if peer shutsdown
