java – Mockito：如何在另一个方法中调用mock方法

2023年5月7日 348次阅读

我是mockito的新手,我正在使用mockito来测试调用另一个方法的方法,并且调用方法返回字符串.

我试过但我无法写测试.请帮忙

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;
  }
}

我想在这里模拟xml响应来测试processIncomingData方法..这个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.我认为如果我可以从socket模拟xmlResponse,套接字无关紧要.请给出任何有用的答案

最佳答案 现在您已经发布了它,如何模拟它的答案就在这里.
