【问题描述】:
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;
}
}
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。如果我可以从套接字模拟 xmlResponse,我认为套接字无关紧要。请给出任何有用的答案
【问题讨论】:
-
显示
xmlResponse是如何生成的。您需要在String xmlResponse = ...;行使用模拟。如果这是一个实例方法调用,请使用Mockito模拟 bean(读取套接字客户端)。如果这是一个静态调用,请使用JMockit模拟静态调用。 -
我正在从套接字服务器读取 xml 响应。它是字符串格式,如“
”等123 -
您的单元测试不应依赖于套接字服务器。你应该在嘲笑客户。
-
你能告诉我如何模拟客户端吗?
-
发布更多代码。具体来说,1) 检索
xmlResponse的完整代码行 2)MyClass如何获取它正在使用的客户端实例。
