c# - 如何对将网络流发送到服务器的功能进行单元测试
问题描述
我已经实现了一个简单的聊天程序(在这里找到:http ://csharp.net-informations.com/communications/csharp-chat-server.htm ),我希望在我的客户端中对函数“button1_Click”进行单元测试,但是我该怎么做?我不知道如何测试该函数输出 coorect 流。
我对单元测试的世界还很陌生,所以任何帮助都会得到帮助:)
客户端如下:
using System;
using System.Windows.Forms;
using System.Text;
using System.Net.Sockets ;
using System.Threading;
namespace WindowsApplication2
{
public partial class Form1 : Form
{
System.Net.Sockets.TcpClient clientSocket = new System.Net.Sockets.TcpClient();
NetworkStream serverStream = default(NetworkStream);
string readData = null;
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
byte[] outStream = System.Text.Encoding.ASCII.GetBytes(textBox2.Text + "$");
serverStream.Write(outStream, 0, outStream.Length);
serverStream.Flush();
}
private void button2_Click(object sender, EventArgs e)
{
readData = "Conected to Chat Server ...";
msg();
clientSocket.Connect("127.0.0.1", 8888);
serverStream = clientSocket.GetStream();
byte[] outStream = System.Text.Encoding.ASCII.GetBytes(textBox3.Text + "$");
serverStream.Write(outStream, 0, outStream.Length);
serverStream.Flush();
Thread ctThread = new Thread(getMessage);
ctThread.Start();
}
private void getMessage()
{
while (true)
{
serverStream = clientSocket.GetStream();
int buffSize = 0;
byte[] inStream = new byte[10025];
buffSize = clientSocket.ReceiveBufferSize;
serverStream.Read(inStream, 0, buffSize);
string returndata = System.Text.Encoding.ASCII.GetString(inStream);
readData = "" + returndata;
msg();
}
}
private void msg()
{
if (this.InvokeRequired)
this.Invoke(new MethodInvoker(msg));
else
textBox1.Text = textBox1.Text + Environment.NewLine + " >> " + readData;
}
}
}
服务器如下:
using System;
using System.Threading;
using System.Net.Sockets;
using System.Text;
using System.Collections;
namespace ConsoleApplication1
{
class Program
{
public static Hashtable clientsList = new Hashtable();
static void Main(string[] args)
{
TcpListener serverSocket = new TcpListener(8888);
TcpClient clientSocket = default(TcpClient);
int counter = 0;
serverSocket.Start();
Console.WriteLine ("Chat Server Started ....");
counter = 0;
while ((true))
{
counter += 1;
clientSocket = serverSocket.AcceptTcpClient();
byte[] bytesFrom = new byte[10025];
string dataFromClient = null;
NetworkStream networkStream = clientSocket.GetStream();
networkStream.Read(bytesFrom, 0, (int)clientSocket.ReceiveBufferSize);
dataFromClient = System.Text.Encoding.ASCII.GetString(bytesFrom);
dataFromClient = dataFromClient.Substring(0, dataFromClient.IndexOf("$"));
clientsList.Add(dataFromClient, clientSocket);
broadcast(dataFromClient + " Joined ", dataFromClient, false);
Console.WriteLine(dataFromClient + " Joined chat room ");
handleClinet client = new handleClinet();
client.startClient(clientSocket, dataFromClient, clientsList);
}
clientSocket.Close();
serverSocket.Stop();
Console.WriteLine("exit");
Console.ReadLine();
}
public static void broadcast(string msg, string uName, bool flag)
{
foreach (DictionaryEntry Item in clientsList)
{
TcpClient broadcastSocket;
broadcastSocket = (TcpClient)Item.Value;
NetworkStream broadcastStream = broadcastSocket.GetStream();
Byte[] broadcastBytes = null;
if (flag == true)
{
broadcastBytes = Encoding.ASCII.GetBytes(uName + " says : " + msg);
}
else
{
broadcastBytes = Encoding.ASCII.GetBytes(msg);
}
broadcastStream.Write(broadcastBytes, 0, broadcastBytes.Length);
broadcastStream.Flush();
}
} //end broadcast function
}//end Main class
public class handleClinet
{
TcpClient clientSocket;
string clNo;
Hashtable clientsList;
public void startClient(TcpClient inClientSocket, string clineNo, Hashtable cList)
{
this.clientSocket = inClientSocket;
this.clNo = clineNo;
this.clientsList = cList;
Thread ctThread = new Thread(doChat);
ctThread.Start();
}
private void doChat()
{
int requestCount = 0;
byte[] bytesFrom = new byte[10025];
string dataFromClient = null;
Byte[] sendBytes = null;
string serverResponse = null;
string rCount = null;
requestCount = 0;
while ((true))
{
try
{
requestCount = requestCount + 1;
NetworkStream networkStream = clientSocket.GetStream();
networkStream.Read(bytesFrom, 0, (int)clientSocket.ReceiveBufferSize);
dataFromClient = System.Text.Encoding.ASCII.GetString(bytesFrom);
dataFromClient = dataFromClient.Substring(0, dataFromClient.IndexOf("$"));
Console.WriteLine("From client - " + clNo + " : " + dataFromClient);
rCount = Convert.ToString(requestCount);
Program.broadcast (dataFromClient, clNo, true);
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
}//end while
}//end doChat
} //end class handleClinet
}//end namespace
