### Question:
NetworkRpcInputEntityBuilder extends AbstractBuilder<Map<String, String>, RpcNetworkTopologyOperationInputEntity> { @Override public RpcNetworkTopologyOperationInputEntity build(DelegateExecution execution, Map<String, String> inputs) { RpcNetworkTopologyOperationInputEntity rpcNetworkTopologyOperationInputEntity = new RpcNetworkTopologyOperationInputEntity(); NetworkTopologyOperationInputEntity networkTopologyOperationInputEntity = getNetworkTopologyOperationInputEntity(execution, inputs); rpcNetworkTopologyOperationInputEntity.setInput(networkTopologyOperationInputEntity); return rpcNetworkTopologyOperationInputEntity; }  @Override RpcNetworkTopologyOperationInputEntity build(DelegateExecution execution, Map<String, String> inputs);  }### Answer:
@Test public void buildTest() { networRpcInputEntityBuilder.build(delegateExecution, null); }
