21 * @file transport/test_transport_api_dv.c
22 * @brief base test case for dv transport (separated from other transport
23 * testcases for two reasons. 1) dv-service relies on core and other
24 * transport plugins, dv plugin relies on dv-service, so dv-plugin needs
25 * to live here, and 2) a dv plugin testcase is different from other
26 * tranport plugin testcases because we need at least three peer to test
29 * This test case tests DV functionality. Specifically it starts three
30 * peers connected in a line (1 <-> 2 <-> 3). Then a message is transmitted
31 * from peer 1 to peer 3. Assuming that DV is working, peer 2 should have
32 * gossiped about peer 3 to 1, and should then forward a message from one
