我需要创建一个集成测试,演示如何将UDP数据包成功发送到远程软件。远程软件在测试环境中是不可用的(这是一个传统但仍支持的版本),并且不在我的控制之下,所以我认为我会设置一个测试,至少证明命令按预期发生。阅读this question's answers后,我建立了我的代码如下:UDP算法的集成测试
public void TestRemoteCommand()
{
//A "strategy picker"; will instantiate a version-specific
//implementation, using a UdpClient in this case
var communicator = new NotifyCommunicator(IPAddress.Loopback.ToString(), "1.0");
const string message = "REMOTE COMMAND";
const int port = <specific port the actual remote software listens on>;
var receivingEndpoint = new IPEndPoint(IPAddress.Loopback, port);
//my test listener; will listen on the same port already connected to by
//the communicator's UdpClient (set up without sharing)
var client = new UdpClient();
client.Client.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true);
client.Client.Bind(receivingEndpoint);
//Results in the UDP diagram being sent
communicator.SendRemoteCommand();
//This assertion always fails
Assert.IsTrue(client.Available > 0);
var result = client.Receive(ref receivingEndpoint);
Assert.AreEqual(result.Select(b => (char)b).ToArray(), message.ToCharArray());
}
但是,这是行不通的如上评论。有人看到我在这里失踪了吗?
原来是它的一部分。我再次抨击它,并发现我在所有的端口上监听,而不是在特定的端口上监听,而这个端口不工作。但是,是的,我还不得不抛出一个快速的Thread.Sleep()语句来确保数据包通过硬件层进入接收存储桶。它实际上运行良好,一次运行一个测试,但在套件中失败。 – KeithS 2011-02-02 20:21:43
