Hi Akalanka, Srinath an i had a discussion. One of the aspects Srinath pointed out was to assure the use case when there're let's say 3 subscribers bound to the same topic and two subscribers acked instantly but the third took more time to ack which will result in the message being assigned to the retry cycle. At a time like that we need a test to verify the following,
1) Ensure that the subscribers who acked will not receive duplicate messages. 2) The subscriber with acked later received the message, Thanks, Pamod On Mon, Nov 3, 2014 at 4:45 PM, Akalanka Pagoda Arachchi <[email protected] > wrote: > Hi all, > > According to hasitha's mail I have identified following test cases to > include in the MQTT tests. > > *Functional Tests* > > > - Test MQTT for QOS 0,1 and 2 > - Test long topic hierarchies > - Test MQTT wildcards > - Test duplicate client Id > - Test last will testament > > > > *Load Tests* > > > - Number of clients - 50 subscribers, 50 publishers with 100000 > messages > - QOS 0,1 and 2 with 100000 messages > - Disconnection between send/receive for 100000 messages > - Payload Size 1MB message send/receive > > > Please provide if there are any other scenarios that needs to be tested > for MQTT. > > Thanks, > Akalanka > > On Thu, Oct 30, 2014 at 3:18 PM, Hasitha Amal De Silva <[email protected]> > wrote: > >> 2nd link is not valid.
