org.xmlBlaster.test.stress
Class LoadTestSub

java.lang.Object
  junit.framework.Assert
      junit.framework.TestCase
          org.xmlBlaster.test.stress.LoadTestSub

All Implemented Interfaces:

junit.framework.Test, I_Callback

public class LoadTestSub
extends junit.framework.TestCase
implements I_Callback

This client does a subscribe() with many publish() calls.
The same message is published 1000 times, to measure messages/second performance.

This client may be invoked multiple time on the same xmlBlaster server, as it cleans up everything after his tests are done.

Invoke examples:

    java junit.textui.TestRunner org.xmlBlaster.test.stress.LoadTestSub
    java junit.swingui.TestRunner org.xmlBlaster.test.stress.LoadTestSub

Constructor Summary

LoadTestSub()

LoadTestSub(Global glob, java.lang.String testName, java.lang.String loginName, java.lang.String passwd, int numPublish, int burstModePublish, boolean publishOneway, boolean persistent)
Constructs the LoadTestSub object.

Method Summary

void	doPublish() TEST: Construct a message and publish it.
void	doSubscribeXPath() TEST: Subscribe to messages with XPATH.
static void	main(java.lang.String[] args) Deprecated. Use the TestRunner from the testsuite to run it: java -Djava.compiler= junit.textui.TestRunner org.xmlBlaster.test.stress.LoadTestSub
protected void	setUp() Sets up the fixture.
static junit.framework.Test	suite() Method is used by TestRunner to load these tests
protected void	tearDown() Tears down the fixture.
void	testManyPublish() TEST: Construct a message and publish it, the previous XPath subscription should match and send an update.
java.lang.String	update(java.lang.String cbSessionId, UpdateKey updateKey, byte[] content, UpdateQos updateQos) This is the callback method invoked from xmlBlaster delivering us a new asynchronous message.
(package private) static void	usage()
private void	waitOnUpdate(long timeout, int numWait) Little helper, waits until the wanted number of messages are arrived or returns when the given timeout occurs.

Constructor Detail

LoadTestSub

public LoadTestSub()

LoadTestSub

public LoadTestSub(Global glob,
                   java.lang.String testName,
                   java.lang.String loginName,
                   java.lang.String passwd,
                   int numPublish,

                   boolean publishOneway,
                   boolean persistent)

Constructs the LoadTestSub object.

Parameters:

testName - The name used in the test suite

loginName - The name to login to the xmlBlaster

numPublish - The number of messages to send

burstModePublish - send given number of publish messages in one bulk

Method Detail

setUp

protected void setUp()

Sets up the fixture.

Connect to xmlBlaster and login

Overrides:

setUp in class junit.framework.TestCase

tearDown

protected void tearDown()

Tears down the fixture.

cleaning up .... erase() the previous message OID and logout

Overrides:

tearDown in class junit.framework.TestCase

doSubscribeXPath

public void doSubscribeXPath()

TEST: Subscribe to messages with XPATH.

The returned subscribeOid is checked

doPublish

public void doPublish()

TEST: Construct a message and publish it.

The returned publishOid is checked

testManyPublish

public void testManyPublish()

TEST: Construct a message and publish it,
the previous XPath subscription should match and send an update.

update

public java.lang.String update(java.lang.String cbSessionId,
                               UpdateKey updateKey,
                               byte[] content,
                               UpdateQos updateQos)

This is the callback method invoked from xmlBlaster delivering us a new asynchronous message.

Specified by:

update in interface I_Callback

Parameters:

cbSessionId - The session ID specified by the client which registered the callback. You can specify a cbSessionId during connection (with ConnectQos) and this is bounced back here so you can authenticate the message.

updateKey - The arrived key containing the topic name

content - The arrived message content. This is your payload.

See Also:

I_Callback.update(String, UpdateKey, byte[], UpdateQos)

waitOnUpdate

private void waitOnUpdate(long timeout,
                          int numWait)

Little helper, waits until the wanted number of messages are arrived or returns when the given timeout occurs.

Parameters:

timeout - in milliseconds

numWait - how many messages to wait

suite

public static junit.framework.Test suite()

Method is used by TestRunner to load these tests

usage

static void usage()

main

public static void main(java.lang.String[] args)

Deprecated. Use the TestRunner from the testsuite to run it:

   java -Djava.compiler= junit.textui.TestRunner org.xmlBlaster.test.stress.LoadTestSub

Invoke: java org.xmlBlaster.test.stress.LoadTestSub
You can use the command line option -numPublish 5000 to change the number of messages sent.
