20/**
21 * @file transport/test_transport_address_switch.c
22 * @brief base test case for transport implementations
23 *
24 * This test case tests if peers can successfully switch addresses when
25 * connected for plugins supporting multiple addresses by monitoring transport's
26 * statistic values.
27 *
28 * This test starts 2 peers and connects them. When connected test messages
29 * are transmitted from peer 2 to peer 1. The test monitors transport's
30 * statistics values for information about address switch attempts.
31 *
32 * The test passes with success if one of the peers could successfully switch
33 * addresses in connected state and a test message was successfully transmitted
34 * after this switch.
35 *
36 * Since it is not possible to trigger an address switch from outside,
37 * the test returns "77" (skipped) when no address switching attempt
38 * takes place. It fails if an address switch attempt fails.
39 *
40 * NOTE: The test seems largely useless right now, as we simply NEVER
41 * switch addresses under the test conditions. However, it may be a
42 * good starting point for a future test. For now, it always times
43 * out and returns "77" (skipped), so we set the timeout suitably low.
