/* unit tests for /core/Messenger.c
* Design:
* Just call every non-static function in Messenger.c, checking that
* they return as they should with check calls. "Bad" calls of the type
* function(bad_data, good_length) are _not_ checked for, this type
* of call is the fault of the client code.
*
* Note:
* None of the functions here test things that rely on the network, i.e.
* checking that status changes are received, messages can be sent, etc.
* All of that is done in a separate test, with two local clients running. */
