Init JMS Topic before start of test

Hi,

I would like to know how to clear a JMS topic before test execution. I have found code below via this link. How do I change the code to only read the JMS topics until there is nothing more on the topic?

Motivation for this: I have created a DataSource Loop test. But sometimes there are already (alot of) messages on the queue that need to be cleared, so that what I put on the topic and my test step to verify the topic are in sync.

 

Thanks in advance!

import com.eviware.soapui.impl.wsdl.submit.transports.jms.util.HermesUtils
import com.eviware.soapui.impl.wsdl.submit.transports.jms.JMSEndpoint
import hermes.Hermes
import javax.jms.*

def jmsEndpoint = new  JMSEndpoint("jms://activeMQSession::queue_testQ1::queue_testQ1");
def hermes = HermesUtils.getHermes( context.testCase.testSuite.project, jmsEndpoint.sessionName)
def jmsConnectionHolder = new JMSConnectionHolder( jmsEndpoint, hermes, false, null ,null ,null);

Session queueSession = jmsConnectionHolder.getSession();
Queue queueSend = jmsConnectionHolder.getQueue( jmsConnectionHolder.getJmsEndpoint().getSend() );
Queue queueBrowse = jmsConnectionHolder.getQueue( jmsConnectionHolder.getJmsEndpoint().getReceive() );

MessageProducer messageProducer =queueSession.createProducer( queueSend );
TextMessage textMessageSend = queueSession.createTextMessage();
textMessageSend.setText( "jms message from groovy");
messageProducer.send( textMessageSend );
textMessageSend.setText( "another jms message from groovy");
messageProducer.send( textMessageSend );

QueueBrowser qb  = queueSession.createBrowser(queueBrowse);
Enumeration en= qb.getEnumeration();
while(en.hasMoreElements()){
    TextMessage tm = (TextMessage)en.nextElement();
    log.info tm.getText()
    }
jmsConnectionHolder.closeAll()// don't forget to close session and connection
