Testing MQTT packet types - any simple python tests anyone has ?

[Stefan Kwiatkowski]

I wish to test against all 15 control packet types (http://docs.oasis-open.org/mqtt/mqtt/v3.1.1/os/mqtt-v3.1.1-os.html#_Table_2.1_-)  of MQTT - does anyone have some simple Python tests that go through all of them so as to carry out some regression testing against the same or new Brokers ?  Might need some code on the Server to carry out the Server to Client calls listed as well.
