Class TestReferenceCount

java.lang.Object
  junit.framework.Assert
      junit.framework.TestCase
          org.xmlBlaster.test.topic.TestReferenceCount

All Implemented Interfaces:

I_ConnectionStateListener, junit.framework.Test

public class TestReferenceCount

extends junit.framework.TestCase

implements I_ConnectionStateListener

Tests the correct reference counting for persistent messages after recovery.

   1. Start xmlBlaster server
   2. Publish two messages
   3. Subscribe to message and block in callback
   4. Kill server and clients
   5. Restart server
   6. Start same subscriber - it will receive the message from 3.
   7. Start another subscriber: we expect an update
   If the reference counter is not properly set on recovery
   test 7. will fail.
 

Invoke examples:

   java junit.textui.TestRunner org.xmlBlaster.test.topic.TestReferenceCount
   java junit.swingui.TestRunner -noloading org.xmlBlaster.test.topic.TestReferenceCount

Method Detail

setUp

protected void setUp()

Sets up the fixture.

Connect to xmlBlaster and login

tearDown

protected void tearDown()

Tears down the fixture.

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

doConnect

private TestReferenceCount.Client doConnect(java.lang.String loginName,
                                            I_Callback cb)

reachedAlive

public void reachedAlive(ConnectionStateEnum oldState,
                         I_XmlBlasterAccess connection)

This is the callback method invoked from I_XmlBlasterAccess informing the client in an asynchronous mode if the connection was established.

This method is enforced through interface I_ConnectionStateListener

Specified by:

reachedAlive in interface I_ConnectionStateListener

Parameters:

oldState - The previous state of the connection.

reachedPolling

public void reachedPolling(ConnectionStateEnum oldState,
                           I_XmlBlasterAccess connection)

Description copied from interface: I_ConnectionStateListener

This is the callback method invoked from XmlBlasterAccess informing the client that the connection state has changed to POLLING.

Specified by:

reachedPolling in interface I_ConnectionStateListener

Parameters:

oldState - The previous state of the connection.

reachedDead

public void reachedDead(ConnectionStateEnum oldState,
                        I_XmlBlasterAccess connection)

Description copied from interface: I_ConnectionStateListener

This is the callback method invoked from XmlBlasterAccess informing the client that the connection was lost (i.e. when the state of the connection has gone to DEAD).

Specified by:

reachedDead in interface I_ConnectionStateListener

Parameters:

oldState - The previous state of the connection.

suite

public static junit.framework.Test suite()

Method is used by TestRunner to load these tests

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.topic.TestReferenceCount

Invoke: java org.xmlBlaster.test.topic.TestReferenceCount
