Could someone help me to setup a scenario.  
I want my test to have 10 users posting every second for 3 minutes.

Here is how my scenario and setup are:  
val scn = scenario("MQTT publish).exec(publish)

setUp(scn.inject(atOnceUsers(10))).protocols(mqttConf)

Thank you

Probably inject constantUserPerSec(10) during(3 minutes) ?
