/**
* @file cadet/test_cadeT.c
* @brief testcase for cadet.c
* @author xrs
*
* Goal:
* - test session resumption after a hard channel breakup
*
* ToDos:
* - setup peer A
* - setup peer B
* - setup cadet on peer B listening on port 1234
* - create a channel from peer A to B
* - create method to find out session initiator
* - send a message over channel
* - check if message was received
* - breakup the connection without sending a channel destroy message
* - assert tunnel is down
* - resume channel (second handshake for tunnel)
* - send second message over channel
* - check if message was receveived
* - end test
*
* Questions:
* - can we simulate hard breakups with TESTBED?
* - yes, with GNUNET_TESTBED_underlay_configure_link
* - how can we test the sublayers of CADET, e.g. connection, tunnel, channel?
*
* Development
* - red -> green -> refactor (cyclic)
