Error starting escalus story when user have offline messages #197
Description
I'm trying to test offline messages using escalus. When I'm trying to start escalus story for user who have offline messages, I'm getting following error:
** (ErlangError) Erlang error: {:assertion_failed, :assert, :is_presence, {:xmlel, "message", [{"xml:lang", "en"}, {"to", "[email protected]/res1"}, {"from", "[email protected]/res1"}], [{:xmlel, "archived", [{"by", "[email protected]"}, {"id", "8512ba7a-04fd-11e9-bc0e-69dacdbc2072"}, {"xmlns", "urn:xmpp:mam:tmp"}], []}, {:xmlel, "stanza-id", [{"by", "[email protected]"}, {"id", "8512ba7a-04fd-11e9-bc0e-69dacdbc2072"}, {"xmlns", "urn:xmpp:sid:0"}], []}, {:xmlel, "seq", [{"id", "2"}, {"xmlns", "urn:message:seq"}], []}, {:xmlel, "delay", [{"from", "example2.com"}, {"stamp", "2018-12-21T08:50:51.830393Z"}, {"xmlns", "urn:xmpp:delay"}], [xmlcdata: "Offline storage"]}, {:xmlel, "body", [], [xmlcdata: "offline message"]}]}, '<message xml:lang=\'en\' to=\'[email protected]/res1\' from=\'[email protected]/res1\'><archived by=\'[email protected]\' id=\'8512ba7a-04fd-11e9-bc0e-69dacdbc2072\' xmlns=\'urn:xmpp:mam:tmp\'/><stanza-id by=\'[email protected]\' id=\'8512ba7a-04fd-11e9-bc0e-69dacdbc2072\' xmlns=\'urn:xmpp:sid:0\'/><seq id=\'2\' xmlns=\'urn:message:seq\'/><delay from=\'example2.com\' stamp=\'2018-12-21T08:50:51.830393Z\' xmlns=\'urn:xmpp:delay\'>Offline storage</delay><body>offline message</body></message>'}
Short investigation shows that escalus story aways wait for presences after starting client (https://github.com/esl/escalus/blob/master/src/escalus_story.erl#L136) but this behaviour is not fully correct in my case.
