I am a beginner in Java. I have built a client-server group chat application watching tutorials. I read a lot about unit tests and can implement in simple maths problems but i don't know how does it work out for complex codes. So I want to see a demo of that which will make it easy to understand testing for rest parts. One part of the code is the 'server' class and it is:
import java.io.*;
import java.net.ServerSocket;
import java.net.Socket;
//import java.awt.event.*;
public class Server {
private final ServerSocket s;
public Server(ServerSocket serverSocket)
{
this.s = serverSocket;
//this.display = display;
}
public void startServer() {
try {
// Listen for connections (clients to connect) on port 1234.
while (!s.isClosed()) {
// Will be closed in the Client Handler.
Socket socket = s.accept();
System.out.println("A new client has connected!");
ClientHandler clientHandler = new ClientHandler(socket);
Thread thread = new Thread(clientHandler);
// The start method begins the execution of a thread.
// When you call start() the run method is called.
// The operating system schedules the threads.
thread.start();
}
} catch (IOException e) {
closeServerSocket();
}
}
// Close the server socket gracefully.
public void closeServerSocket() {
try {
if (s != null) {
s.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
// Run the program.
public static void main(String[] args) throws IOException {
ServerSocket s = new ServerSocket(1234);
Server server = new Server(s);
server.startServer();
}
}
and the test I want to perform are:
import static org.junit.Assert.*;
public class ServerTeste {
@org.junit.Test
public void startServer() {
}
@org.junit.Test
public void closeServerSocket() {
f
}
}
@org.junit.Test
public void main() {
}
}
NB: Apologies for any mistake because I am complete beginner.
