/**
* @file transport/test_transport_api_manipulation_send_tcp.c
* @brief base test case for transport traffic manipulation implementation
+ * based onf cfg
*
- * This test case will setup 2 peers and connect them, the first message
- * will be sent without manipulation, then a send delay of 1 second will
- * be configured and 1 more message will be sent. Time will be measured.
+ * Peer 1 has inbound and outbound delay of 100ms
+ * Peer 2 has no inbound and outbound delay
*
- * In addition the distance on receiver side will be manipulated to be 10
+ * We send a request from P1 to P2 and expect delay of >= TEST_DELAY us
+ * Then we send response from P2 to P1 and expect delay of >= TEST_DELAY us
