### Question:
NeutronOvsdbIidFactory { public static InstanceIdentifier<ExternalGatewayAsL3Endpoint> neutronGbpExternalGatewayIidWildcard() { return InstanceIdentifier.builder(Mappings.class) .child(NeutronByGbpMappings.class) .child(ExternalGatewaysAsL3Endpoints.class) .child(ExternalGatewayAsL3Endpoint.class) .build(); }  static InstanceIdentifier<Topology> topologyIid(TopologyId ovsdbTopologyId); static InstanceIdentifier<OvsdbNodeAugmentation> ovsdbNodeAugmentationIid(TopologyId ovsdbTopologyId); static InstanceIdentifier<ExternalGatewayAsL3Endpoint> neutronGbpExternalGatewayIidWildcard(); static InstanceIdentifier<EndpointByPort> endpointByPortIid(UniqueId portId); static InstanceIdentifier<NeutronByGbpMappings> neutronGbpMappingsIidWildcard(); static InstanceIdentifier<Node> nodeIid(TopologyId ovsdbTopologyId, NodeId nodeId); @SuppressWarnings("checkstyle:LineLength") // Longer lines in this method are caused by long package names. static InstanceIdentifier<org.opendaylight.yang.gen.v1.urn.opendaylight.inventory.rev130819.nodes.Node> nodeIid(
            org.opendaylight.yang.gen.v1.urn.opendaylight.inventory.rev130819.NodeId nodeId);  }### Answer:
@Test public void test_NeutronGbpExternalGatewayIidWildcard() { InstanceIdentifier<ExternalGatewayAsL3Endpoint> iid = NeutronOvsdbIidFactory.neutronGbpExternalGatewayIidWildcard(); assertNotNull(iid); Class<?>[] expectedTypes = {Mappings.class, NeutronByGbpMappings.class, ExternalGatewaysAsL3Endpoints.class, ExternalGatewayAsL3Endpoint.class}; assertPathArgumentTypes(iid.getPathArguments(), expectedTypes); assertEquals(ExternalGatewayAsL3Endpoint.class, iid.getTargetType()); assertTrue(iid.isWildcarded()); }
