c# - 如何测试我的套接字异常处理代码？

Question

我有以下代码:

try
{
  mainSocket = new Socket(AddressFamily.InterNetwork, 
    SocketType.Stream, ProtocolType.Tcp);
  IPEndPoint ipEndPoint = new IPEndPoint(IPAddress.Any, serverPort);
  mainSocket.Bind(ipEndPoint);
  mainSocket.Listen(MAX_CONNECTIONS);
  mainSocket.BeginAccept(new AsyncCallback(serverEndAccept), mainSocket);
  OnNetworkEvents eventArgs = 
    new OnNetworkEvents(true, "Listening for Connection");
  OnUpdateNetworkStatusMessage(this, eventArgs);
}
catch (SocketException e)
{
  // add code here
}
catch (ObjectDisposedException e)
{
  // add code here
}

如果服务器始终成功监听，我如何测试代码的 SocketException？

Answer 1

不要针对实时网络进行测试。模拟套接字并针对抛出 SocketException 的模拟进行测试。
