Mockito:How to mock method called inside another method
提问by Lakshya
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
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，并且被调用的方法返回字符串。我试过了，但我无法编写测试。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;
}
}
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
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套接字模拟 xmlResponse，套接字将无关紧要。请给出任何有用的答案

Now that you have posted it, the answer to how to mock it is here.
既然你已经发布了它，如何模拟它的答案就在这里。

You can try the spymethod:
你可以试试这个spy方法：
MyClass myClass = spy(new MyClass());
when(myClass.forwardRequest("foo")).thenReturn("bar");
then when you call
然后当你打电话
myClass.processIncominData("baz");
the response will be "bar" (if request is "foo")
响应将是“bar”（如果请求是“foo”）
PS: When you need to mock class under test it shows some problem with your design.
PS：当您需要模拟被测类时，它表明您的设计存在一些问题。
