### Question:
FaasIidFactory { public static InstanceIdentifier<MappedTenantsEntities> mappedTenantsEntitiesIid() { return InstanceIdentifier.builder(MappedTenantsEntities.class).build(); }  static InstanceIdentifier<LogicalNetworks> logicalNetworksIid(); static InstanceIdentifier<LogicalNetwork> logicalNetworkIid(EndpointGroupId consumerEpgId,
            TenantId consumerTenantId, ContractId contractId, EndpointGroupId providerEpgId, TenantId providerTenantId); static InstanceIdentifier<MappedTenantsEntities> mappedTenantsEntitiesIid(); static InstanceIdentifier<MappedSubnet> mappedSubnetIid(TenantId gbpTenantId, SubnetId subnetId); static InstanceIdentifier<MappedTenant> mappedTenantIid(TenantId gbpTenantId); static InstanceIdentifier<MappedEntity> mappedEntityIid(TenantId gbpTenantId); static InstanceIdentifier<MappedContract> mappedContractIid(TenantId gbpTenantId, ContractId contractId); static InstanceIdentifier<MappedEndpoint> mappedEndpointIid(TenantId gbpTenantId,
            MappedEndpointKey mappedEndpointKey);  }### Answer:
@Test public void testMappedTenantsEntitiesIid() { assertNotNull(FaasIidFactory.mappedTenantsEntitiesIid()); }
