Java 测试Apache Camel Junit的所有进程和路由

我正在尝试验证路由的所有进程，但在它开始中断后，start工作正常。请为此给我一些有用的参考或示例。提前感谢

在org.apache.camel.processor.SendProcessor.process（SendProcessor.java:145）

上，测试框架不会自动启动

CamelContext

，因为您正在使用

AdviceWith

，以允许您在路由启动之前向路由添加建议。添加建议后，在

doPostSetup

末尾添加对

startCamelContext（）

的调用

另外，

append

似乎不是

文件

组件的有效属性，因此您需要删除

append=true

正确的解决方案是，但此测试回避了一个问题，即此处实际测试的是什么。你在模拟你的路线，有效地，你只是在真正测试处理器。最好是单独测试处理器，而不是嵌入到这样的路径中（如果没有其他方法的话），以实现
