### Question:
Messagizer implements SessionPacket, TransportMessage { public void sessionNotify( Object event ) throws Exception { session.sessionNotify( event ); } Messagizer( TransportPacket transport, String uri, Resources resources );  Messagizer( TransportPacket transport, URL uri, Resources resources ); TransportPacket getTransport(); @Override String toString(); void sessionPacket( Who sender, FlexBuffer buf ); void transportMessage( Who recipient, Message msg ); Object sessionQuery( Object query ); void sessionControl( Object control, Object value ); void sessionNotify( Object event ); Object transportQuery( Object query ); void transportControl( Object control, Object value ); void transportNotify( Object event ); SessionMessage getSession(); void setSession( SessionMessage session ); static final String FORMAT; }### Answer:
@Test public void sessionNotify() throws Exception { Object EVENT = "foo"; assertNull( session.what ); assertNull( session.event ); m.sessionNotify( EVENT ); assertSame( What.SESSION_NOTIFY, session.what ); assertSame( EVENT, session.event ); }
