* @file transport/test_transport_address_switch.c
* @brief base test case for transport implementations
*
- * This test case tests if peers can successfully switch address when connected
- * connected by monitoring statistic values
+ * This test case tests if peers can successfully switch addresses when
+ * connected for plugins supporting multiple addresses by monitoring transport's
+ * statistic values.
+ *
+ * This test starts 2 peers and connects them. When connected test messages
+ * are transmitted from peer 2 to peer 1. The test monitors transport's
+ * statistics values for information about address switch attempts.
+ *
+ * The test passes with success if one of the peers could successfully switch
+ * addresses in connected state and a test message was successfully transmitted
+ * after this switch.
+ *
+ * Since it is not possible to trigger an address switch from
+ * outside, the test still passes when no address switching attempt takes
+ * place. It fails if an address switch attempt fails.
