### Question:
ArpFlowFactory { public static Action createSendToControllerAction(int order) { return new ActionBuilder().setOrder(order) .setKey(new ActionKey(order)) .setAction( new OutputActionCaseBuilder().setOutputAction( new OutputActionBuilder().setMaxLength(0xffff) .setOutputNodeConnector(new Uri(OutputPortValues.CONTROLLER.toString())) .build()).build()) .build(); }  static EthernetMatch createEthernetMatch(MacAddress destinationMacAddress); static EthernetMatch createEthernetMatch(); static ArpMatch createArpMatch(ArpMessageAddress targetAddress, Ipv4Address senderProtocolAddress); static Action createSendToControllerAction(int order);  }### Answer:
@Test public void createSendToControllerActionTest() { int order = 25; Action action = ArpFlowFactory.createSendToControllerAction(order); Assert.assertEquals(order, action.getOrder().intValue()); Assert.assertEquals(order, action.getKey().getOrder().intValue()); Assert.assertTrue(action.getAction() instanceof OutputActionCase); OutputActionCase output = ((OutputActionCase) action.getAction()); Assert.assertEquals(OutputPortValues.CONTROLLER.toString(), output.getOutputAction().getOutputNodeConnector().getValue()); }
