# Test whether a client sends a correct PUBLISH to a topic with QoS 2.
|
|
|
|
# The client should connect to port 1888 with keepalive=60, clean session set,
|
|
# and client id publish-qos2-test
|
|
# The test will send a CONNACK message to the client with rc=0. Upon receiving
|
|
# the CONNACK the client should verify that rc==0. If not, it should exit with
|
|
# return code=1.
|
|
# On a successful CONNACK, the client should send a PUBLISH message with topic
|
|
# "pub/qos2/test", payload "message" and QoS=2.
|
|
# The test will not respond to the first PUBLISH message, so the client must
|
|
# resend the PUBLISH message with dup=1. Note that to keep test durations low, a
|
|
# message retry timeout of less than 10 seconds is required for this test.
|
|
# On receiving the second PUBLISH message, the test will send the correct
|
|
# PUBREC response. On receiving the correct PUBREC response, the client should
|
|
# send a PUBREL message.
|
|
# The test will not respond to the first PUBREL message, so the client must
|
|
# resend the PUBREL message with dup=1. On receiving the second PUBREL message,
|
|
# the test will send the correct PUBCOMP response. On receiving the correct
|
|
# PUBCOMP response, the client should send a DISCONNECT message.
