org.xmlBlaster.test.stress
Class BigMessage

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

All Implemented Interfaces:

junit.framework.Test, I_Callback

public class BigMessage
extends junit.framework.TestCase
implements I_Callback

This client tests a message of 2 Megabytes published and subscribed

We start our own xmlBlaster server in a thread.

Invoke examples:

    java junit.textui.TestRunner org.xmlBlaster.test.stress.BigMessage
    java junit.swingui.TestRunner -noloading org.xmlBlaster.test.stress.BigMessage

Method Summary

static void	main(java.lang.String[] args) Invoke:
protected void	setUp() Sets up the fixture.
protected void	tearDown() Tears down the fixture.
void	testBigMessage() Create a RDBMS table, fill some data and destroy it again.
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.
private void	waitOnUpdate(long timeout) Little helper, waits until the variable 'messageArrive' is set to true, or fails when the given timeout occurs.

Constructor Detail

BigMessage

public BigMessage(java.lang.String testName)

Constructs the BigMessage object.

Parameters:

testName - The name used in the test suite

Method Detail

setUp

protected void setUp()

Sets up the fixture.

We start an own xmlBlaster server in a separate thread, it is configured to load the tinySQL BigMessage driver to test SQL access (with dBase files)

Then we connect as a client

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

testBigMessage

public void testBigMessage()

Create a RDBMS table, fill some data and destroy it again. We use the tinySQL dBase BigMessage driver for testing.

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)

Little helper, waits until the variable 'messageArrive' is set to true, or fails when the given timeout occurs.

Parameters:

timeout - in milliseconds

main

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

Invoke:

  java org.xmlBlaster.test.stress.BigMessage -contentSize 2000000 -startEmbedded false
