# Test whether a client sends a correct SUBSCRIBE to a topic with QoS 2.
|
|
|
|
# The client should connect to port 1888 with keepalive=60, clean session set,
|
|
# and client id subscribe-qos2-test
|
|
# The test will send a CONNACK message to the client with rc=0. Upon receiving
|
|
# the CONNACK and verifying that rc=0, the client should send a SUBSCRIBE
|
|
# message to subscribe to topic "qos2/test" with QoS=2. If rc!=0, the client
|
|
# should exit with an error.
|
|
# Upon receiving the correct SUBSCRIBE message, the test will reply with a
|
|
# SUBACK message with the accepted QoS set to 2. On receiving the SUBACK
|
|
# message, the client should send a DISCONNECT message.
