MqttSessionSpec: MQTT server connector should produce a duplicate publish on the server given two client connections #454

Closed raboof closed 9 months ago

raboof commented 9 months ago

Appears to be flaky. Seen before #148 #46 

[info] MQTT server connector
[info] - should flow through a server session (68 milliseconds)
[info] - should receive two subscriptions for the same topic (38 milliseconds)
[info] - should unsubscribe a server session (131 milliseconds)
[info] - should reply to a ping request (38 milliseconds)
[info] - should close when no ping request received (1 second, 542 milliseconds)
[info] - should notify on disconnect (248 milliseconds)
[info] - should re-connect given connect, subscribe, disconnect, connect, publish (35 milliseconds)
[info] - should re-connect given connect, subscribe, connect again, publish (41 milliseconds)
[info] - should consume a duplicate publish on the server (27 milliseconds)
[info] - should produce a duplicate publish on the server given two client connections *** FAILED *** (15 seconds, 469 milliseconds)
