我想对使用Netty构建的套接字服务器进行一些单元测试。
套接字服务器具有以下简单代码:
import io.netty.bootstrap.ServerBootstrap;
import io.netty.channel.ChannelFuture;
import io.netty.channel.ChannelInitializer;
import io.netty.channel.ChannelOption;
import io.netty.channel.EventLoopGroup;
import io.netty.channel.nio.NioEventLoopGroup;
import io.netty.channel.socket.SocketChannel;
import io.netty.channel.socket.nio.NioServerSocketChannel;
public class SocketServer implements Runnable {
private int port;
private EventLoopGroup bossGroup;
private EventLoopGroup workerGroup;
private ChannelFuture channelFuture;
private ServerBootstrap bootstrap;
public SocketServer(int port) {
this.port = port;
this.bossGroup = new NioEventLoopGroup();
this.workerGroup = new NioEventLoopGroup();
}
public int getPort() {
return port;
}
@Override
public void run() {
try {
bootstrap = new ServerBootstrap();
bootstrap
.group(bossGroup, workerGroup)
.channel(NioServerSocketChannel.class)
.childHandler(new ChannelInitializer<SocketChannel>() {
@Override
public void initChannel(SocketChannel ch)
throws Exception {
ch.pipeline()
.addLast(new ReceiveMessageServerHandler())
.addLast(new ParseMessageServerHandler());
}
}).option(ChannelOption.SO_BACKLOG, 128).childOption(ChannelOption.SO_KEEPALIVE, true);
// Bind and start to accept incoming connections.
channelFuture = bootstrap.bind(port).sync();
// Wait until the server socket is closed
channelFuture.channel().closeFuture().sync();
} catch (InterruptedException e) {
e.printStackTrace();
} finally {
workerGroup.shutdownGracefully();
bossGroup.shutdownGracefully();
}
}
public void shutdown() throws InterruptedException {
channelFuture.channel().close();
}
}
我首先在MessageHandlers上接收以'\n'分隔的文本消息。我非常需要一个telnet客户端。
我想测试是否可以将不同的消息发送到服务器,并在一定时间内收到某些预期的响应。
我尝试使用Citrus Framework,但无法获得任何结果,因为它没有提供适当的纯文本协议(protocol)(我尝试了Rest,Soap等,但它们对我没有好处)。我在Citrus Reference 2.4中找不到答案。
Citrus 2.4 Reference - HTML Version
最佳答案
您也可以为此使用Citrus Apache Camel集成。您需要citrus-camel模块和camel-netty(http://camel.apache.org/netty.html)或camel-netty4(http://camel.apache.org/netty4.html)依赖项。然后,您可以直接使用Camel Netty组件发送消息:
@Test
@CitrusTest
public void sendNettyMessageTest() {
status(Status.DRAFT);
//sends data to server
send("camel:netty4:tcp://localhost:9123").payload("Message 1");
send("camel:netty4:tcp://localhost:9123").payload("Message 2");
}
这利用了Citrus中的动态端点,在测试运行时创建了端点配置。因此,这里几乎不需要任何其他配置!
