Mockito:如何模拟另一个方法内部调用的方法

问题描述

我对Mockito还是陌生的，并且我正在使用Mockito测试正在调用另一个方法的方法，并且该方法返回字符串.我尝试过，但无法编写测试.请帮助

I am new to mockito and I am using mockito to test method which is calling another method and called method returns string.I tried but I am unable write test. Please help

public class MyClass {
  protected String processIncominData(String input) {
    String request = ...;
    ...
    String response = forwardRequest(request);
    ...
    return response;
  }

  public String forwardRequest(String requestToSocket) {
   String hostname = socketServerName;
    int port = socketServerPort;
    String responseLine=null;
    Socket clientSocket = null;
    PrintStream outs=null;

    BufferedReader is = null;
    BufferedWriter bwriter=null;

    try {
        clientSocket = new Socket(hostname, port);
        outs=new PrintStream(clientSocket.getOutputStream());
        is = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
        bwriter = new BufferedWriter(new OutputStreamWriter(clientSocket.getOutputStream()));

    } catch (UnknownHostException e) {
        LOGGER.error("Don't know about host: " + hostname + e.getMessage());
    } catch (IOException e) {
        LOGGER.error("Couldn't get I/O for the connection to: " + hostname + e.getMessage());
    }

    if (clientSocket == null || outs == null || is == null) {
        LOGGER.error("Something is wrong. One variable is null.");
    }
    try {
        while ( true ) {
            StringBuilder sb = new StringBuilder();
            sb.append(requestToSocket);

            String  request = sb.toString().trim();
            bwriter.write(request);
            bwriter.write("\r\n");
            bwriter.flush();
            responseLine = is.readLine();
            LOGGER.info("Socket returns : " + responseLine);
            //outs.println(responseLine);
            bwriter.close();
        }
    } catch (UnknownHostException e) {
        LOGGER.error("Trying to connect to unknown host: "+ e.getMessage());
    } catch (IOException e) {
        LOGGER.error("IOException:  "+ e.getMessage());
    }
    finally{
        try {
            outs.close();
            is.close();
            clientSocket.close();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }
    return responseLine;
  }
}

我想在此处模拟xml响应以测试processIncomingData方法.此响应来自套接字服务器，我正在通过套接字客户端发送请求.我认为如果可以从套接字模拟xmlResponse，套接字就没有关系.请给出任何有用的答案

I want to mock xml response here to test processIncomingData method..This response is coming from socket server and I am sending request by socket client. I think socket will not matter if I can mock xmlResponse from socket. Please give any helpful answer
