+/* 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. */
