How do you test code that uses sockets (TCP)?

Testing code that utilizes sockets (TCP) involves creating a server and client that can communicate over the network. This can be efficiently done by using tools or libraries designed for socket programming in Java. Below is a simple example illustrating how you can establish a TCP connection, send data from a client to a server, and receive a response.


        // Server Code
        import java.io.*;
        import java.net.*;

        public class Server {
            public static void main(String[] args) {
                try (ServerSocket serverSocket = new ServerSocket(8080)) {
                    System.out.println("Server is listening on port 8080");
                    Socket socket = serverSocket.accept();
                    System.out.println("Client connected");

                    InputStream input = socket.getInputStream();
                    BufferedReader reader = new BufferedReader(new InputStreamReader(input));
                    String message = reader.readLine();
                    System.out.println("Message from client: " + message);

                    PrintWriter writer = new PrintWriter(socket.getOutputStream(), true);
                    writer.println("Hello from server!");

                    socket.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }

        // Client Code
        import java.io.*;
        import java.net.*;

        public class Client {
            public static void main(String[] args) {
                try (Socket socket = new Socket("localhost", 8080)) {
                    PrintWriter writer = new PrintWriter(socket.getOutputStream(), true);
                    writer.println("Hello from client!");

                    BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
                    String response = reader.readLine();
                    System.out.println("Response from server: " + response);
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
