Question

我是netty framework的新手。我们有一个API Handler实现SimpleChannelInboundHandler并覆盖ChannelRead0函数，它接受ChannelHandlerContext和FullHTTPRequest.Now我需要进行单元测试模拟输入。任何人都可以帮助我。

让我们假设我想测试我的MyContentExtractionHandler，如下所示：

public class MyContentExtractionHandler extends SimpleChannelInboundHandler<FullHttpRequest> {
    @Override
    protected void channelRead0(ChannelHandlerContext ctx, FullHttpRequest msg) throws Exception {
        int contentLenght = msg.content().capacity();
        byte[] content = new byte[contentLenght];
        msg.content().getBytes(0, content);
        ctx.fireChannelRead(new String(content));
    }
}

我将创建常规DefaultFullHttpRequest并使用mockito来模拟ChannelHandlerContext。我的单元测试看起来像这样：

public class MyContentExtractionHandlerTest {

    @Mock
    ChannelHandlerContext mockCtx = BDDMockito.mock(ChannelHandlerContext.class);

    MyContentExtractionHandler myContentExtractorHandler = new MyContentExtractionHandler();

    @Test
    public void myTest() throws Exception {
        String content = "MyContentHello";
        DefaultFullHttpRequest fullHttpRequest = new DefaultFullHttpRequest(HttpVersion.HTTP_1_1, HttpMethod.POST, "/my /uri", Unpooled.copiedBuffer(content.getBytes()));
        myContentExtractorHandler.channelRead(mockCtx, fullHttpRequest);
        BDDMockito.verify(mockCtx).fireChannelRead(content); //verify that fireChannelRead was called once with the expected result
    }
}

最有可能的是，您的SimpleChannelInboundHandler将成为最终的处理程序。因此，在阅读消息后，不要检查fireChannelRead()检查您调用的任何方法。

在netty中对SimpleChannelInboundHandler <fullhttprequest>进行单元测试
