JUnit + Apache骆驼

Question

Suppose I have these two routes

<camelContext> 
    <route>
        <from ref="incoming" />
        <!-- some processors -->
        <inOnly ref="outgoing" />
    </route>

    <route>
        <from ref="outgoing" />
        <!-- some processors -->
        <inOnly ref="finish" />
    </route>
</camelContext>

In the real context they are JMS queues which is fine. But I want to test that the routing is correct so I changed JMS components in the testContext.xml to:

incoming -> direct
outgoing -> mock
finish -> mock

I want those inOnly queues to be mocks so I can test them for the number of messages. The problem is that a mock queue cannot work as an input queue in the second route. How can I fix this?

Answer 1

I usually embedd an ActiveMQ broker when doing automated integration JUnit tests with Camel and JMS.

I would also consider a simpler scenario where you have "outgoing" as a seda endpoint. Then you would only have to check the "finish" mock endpoint for messages, and you know the entire route works. For more complicated routing scenarios, it takes a bit of thinking to cover it in JUnit tests, if you should do it at all.

您可以使用存根组件而不是JMS等。它的seda / vm在后台排队，因此您可以从其中发送和使用消息http://camel.apache.org/stub
