### Question:
ServiceRpcInputEntityBuilder extends AbstractBuilder<Map<String, String>, RpcServiceTopologyOperationInputEntity> { @Override public RpcServiceTopologyOperationInputEntity build(DelegateExecution execution, Map<String, String> inputs) throws Exception { RpcServiceTopologyOperationInputEntity rpcServiceTopologyOperationInputEntity = new RpcServiceTopologyOperationInputEntity(); ServiceTopologyOperationInputEntity serviceTopologyOperationInputEntity = new ServiceTopologyOperationInputEntity(); loadSdncRequestHeaderEntity(serviceTopologyOperationInputEntity, execution); loadRequestInformationEntity(serviceTopologyOperationInputEntity, execution); loadServiceInformation(serviceTopologyOperationInputEntity, execution); loadServiceRequestInputEntity(serviceTopologyOperationInputEntity, execution); rpcServiceTopologyOperationInputEntity .setServiceTopologyOperationInputEntity(serviceTopologyOperationInputEntity); return rpcServiceTopologyOperationInputEntity; }  @Override RpcServiceTopologyOperationInputEntity build(DelegateExecution execution, Map<String, String> inputs);  }### Answer:
@Test public void buildTest() throws Exception { serviceRpcInputEntityBuilder.build(delegateExecution, null); }
