### Question:
FlexClientManager extends ManageableComponent { protected FlexClient createFlexClient(String id) { return (id == null) ? new FlexClient(this) : new FlexClient(this, id); } FlexClientManager();  FlexClientManager(MessageBroker broker);  FlexClientManager(boolean enableManagement, MessageBroker mbroker); String[] getClientIds(); int getFlexClientCount(); long getFlexClientTimeoutMillis(); void setFlexClientTimeoutMillis(long value); MessageBroker getMessageBroker(); FlexClient getFlexClient(String id); FlexClient getFlexClient(String id, boolean createNewIfNotExist); FlexClientOutboundQueueProcessor createOutboundQueueProcessor(FlexClient flexClient, String endpointId); void monitorAsyncPollTimeout(TimeoutAbstractObject asyncPollTimeout); void monitorScheduledFlush(TimeoutAbstractObject scheduledFlushTimeout); @Override void start(); void stop(); static final String TYPE; }### Answer:
@Test public void testCreateFlexClientWithId() { String id = "abc"; FlexClient client = manager.createFlexClient(id); Assert.assertEquals(id, client.getId()); }
