How to print Gatling JMS request reply

Question

I am new in gatling world and i tried to send messages to TIBCO EMS(Enterprise Message Service) using gatling JMS support. I was able to send the messages but i have no idea how can i print the request reply.

For http requests i just uncomment in logback-test.xml this line:

<logger name="io.gatling.http.engine.response" level="TRACE" />

This is my setup for gatling JMS:

object GetEMSConn {


  val jndiBasedConnectionFactory = jmsJndiConnectionFactory
    .connectionFactoryName("FACTORY_NAME")
    .url("tibjmsnaming://JNDI-A.company-name")
    .credentials("anonymous", "xxx")
    .contextFactory("com.tibco.tibjms.naming.TibjmsInitialContextFactory")

  val jmsProtocol = jms
    .connectionFactory(jndiBasedConnectionFactory)
    //    .matchByCorrelationId
    .matchByMessageId
    .useNonPersistentDeliveryMode
    //    .usePersistentDeliveryMode
    .credentials("credentials", "password")
    .listenerThreadCount(1)
    .replyTimeout(1000.seconds)
}

object JMSScenario {

  val feedData = csv("testData/data.csv").circular

val jmsScenario = scenario("JMS DSL test")
    .repeat(5) {
      feed(feedCID)
        .exec(jms("My test")
          .requestReply
          .queue("MY_QUEUE")
          .textMessage("<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope</soapenv:Body>\n</soapenv:Envelope>")
          .jmsType("SoapAction")
        )
    }
}

class JMSSimulation extends Simulation {

  private val jmsEx = JMSScenario.jmsScenario
    .inject(
      atOnceUsers(1)
    ).protocols(GetEMSConn.jmsProtocol)

setUp(
    jmsEx
  )
    .maxDuration(10.seconds)
    .assertions(global.responseTime.max.lt(5000))
}

When i run the above code i get only this:

I also tried to check with simpleCheck() method:

object JMSScenario {

  val feedData = csv("testData/data.csv").circular

val jmsScenario = scenario("JMS DSL test")
    .repeat(5) {
      feed(feedCID)
        .exec(jms("My test")
          .requestReply
          .queue("MY_QUEUE")
          .textMessage("<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope</soapenv:Body>\n</soapenv:Envelope>")
          .jmsType("SoapAction")
          .check(simpleCheck(checkBodyTextCorrect))
        )
    }

  def checkBodyTextCorrect(m: Message) = {
    // this assumes that the service just does an "uppercase" transform on the text
    print("in check \n")
    m match {
      case tm: TextMessage => tm.getText == "<"
      case _ => false
    }
  }
}

But when i check, it's simply fail the test and i don't see why...

Can anyone help me with information about how can i print the request reply? :)

Answer 1

I found the solution:

add in src/test/resources/logback-test.xml the next line:

<logger name="io.gatling.jms" level="TRACE"/>
