我想在java中通過套接字連接接收文本文件,我設置了服務器端,但在繼續使用客戶端之前,我想知道我製作的代碼是否有效,除非我不知道如何測試。Java socketserver如何測試?
任何幫助將不勝感激..
編輯:我知道該端口是開放的監聽請求,我想是測試會發生什麼,如果它收到任何東西,將它從輸入創建一個文件我可以通過模擬來測試(發送一個文件或字節我不知道)?
public class Server {
private static int port = 8080;
private static int maxConnections = 100000;
// Listen for incoming connections and handle them
public static void startServer() {
int i = 0;
try {
ServerSocket listener = new ServerSocket(port);
Socket server;
System.out.println("Started server on port:" + port);
while ((i++ < maxConnections) || (maxConnections == 0)) {
RunServer connection;
server = listener.accept();
RunServer conn_c = new RunServer(server);
Thread t = new Thread(conn_c);
t.start();
System.out.println("Created new thread");
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
class RunServer implements Runnable {
private Socket server;
RunServer(Socket server) {
this.server = server;
}
public void run() {
int bytesRead;
int current = 0;
BufferedOutputStream bufferedOutputStream = null;
FileOutputStream fileOutputStream = null;
DataInputStream clientData = null;
File file = null;
try {
// creating connection.
System.out.println("connected.");
// receive file
byte[] byteArray = new byte[6022386];
System.out.println("Please wait downloading file");
// reading file from socket
InputStream inputStream = server.getInputStream();
file = new File("toread.txt");
clientData = new DataInputStream(inputStream);
fileOutputStream = new FileOutputStream(file);
bufferedOutputStream = new BufferedOutputStream(fileOutputStream);
bytesRead = inputStream.read(byteArray, 0, byteArray.length);
current = bytesRead;
do {
bytesRead = inputStream.read(byteArray, current, (byteArray.length - current));
if (bytesRead >= 0)
current += bytesRead;
} while (bytesRead > -1);
bufferedOutputStream.write(byteArray, 0, current);
bufferedOutputStream.flush();
ReaderHelper.readTextFile(file);
} catch (IOException e) {
e.printStackTrace();
} catch (NumberFormatException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
} finally {
try {
if (fileOutputStream != null)
fileOutputStream.close();
if (bufferedOutputStream != null)
bufferedOutputStream.close();
if (clientData != null)
clientData.close();
if (server != null)
server.close();
} catch (IOException e) {

你,一個偶然的機會,想單元測試的代碼? – catzilla
