### Question:
AmqpJmsMapMessageFacade extends AmqpJmsMessageFacade implements JmsMapMessageFacade { @Override public Enumeration<String> getMapNames() { return Collections.enumeration(messageBodyMap.keySet()); }  @Override byte getJmsMsgType(); @Override AmqpJmsMapMessageFacade copy(); @Override Enumeration<String> getMapNames(); @Override boolean itemExists(String key); @Override Object get(String key); @Override void put(String key, Object value); @Override Object remove(String key); @Override void clearBody(); @Override boolean hasBody(); @Override JmsMapMessage asJmsMessage();  }### Answer:
@Test public void testNewMessageToSendReportsIsEmpty() throws Exception { AmqpJmsMapMessageFacade amqpMapMessageFacade = createNewMapMessageFacade(); assertFalse(amqpMapMessageFacade.getMapNames().hasMoreElements()); }
@Test public void testNewMessageToSendReturnsEmptyMapNamesEnumeration() throws Exception { AmqpJmsMapMessageFacade amqpMapMessageFacade = createNewMapMessageFacade(); assertNotNull(amqpMapMessageFacade.getMapNames()); Enumeration<String> names = amqpMapMessageFacade.getMapNames(); assertFalse(names.hasMoreElements()); }
