I can send you example JMX file if you want. The clue here is to simulate the socket IO communication. If you want to create it on your own please see this spec: https://github.com/LearnBoost/socket.io-spec

You need take care about the initialization, connection, connection closing etc. You need also to grab the session ID and pass it to your samplers.

You can also use google chrome and see how communication works. Only this browser have support to see communication details.

It would be awesome if you could send me an example... Currently we have an issue with sockets getting disconnected after a while. I managed to send the message, just copy pasted from chrome dev tools.

Thanks for your quick response.

Kind regards,

Marco Franssen

Here is the content of sample JMX file. Just copy and paste and open it w/ JMeter.

I've set project variables: hots and referrer (referrer is not required and probably you can remove it from all places where it is present in load test project, however it was used by logic which I've examined so it remains here) you need to adjust them to URLs which you are calling. You can add the Tree View listener to see communication.

My example works as a streaming and logic which I'm examining is sending messages during 30 seconds time period so I've put delay on connection close - just to receive more messages.

It is just en example how you can use this extension feel free to modify, change or adjust to your expectations.

BTW I've found that this plugin is not ready to examine services w/ high load or soak testing it requires to some fixes on author side however it is better than nothing. You can always do some coding and fix this plugin as well.
