How can you unit test Apache Cache Timer routes?

Question

Using Apache Camel 2.9.1

How do I unit test something like the following?

public class MyRoute extends RouteBuilder {
    @Override
    public void configure() throws Exception {

         from("timer.something?delay=0?repeatCount=1")
             // do some stuff
             .to("{{some.endpoint}}")
             .end()

         from("timer.somethingelse?delay=3000&period=1000")
             // do some stuff
             .to("{{some.other.endpoint}}")
             .end
    }
}

What is exactly that you want to unit test here? Because it's clueless to unit test the timer component (I mean to unit test if it's triggered or not; and if its properties works as it should be): Camel team has done that already.

What is logical to unit test here is the "// do some stuff" part, which you'd do by mocking the endpoints. Your first route will be fired automaticly, while the second will with initial delay. You'll have to wait that much at least to assert anything. In these kind of cases I usually read the endpoint properties from a properties files like

from("timer:somethingelse?{{2nd.timer.properties}}")

and that can be set to

2nd.timer.properties=delay=3000&period=1000 //in prod
2nd.timer.properties=delay=0 //during tests

So that one is triggered at startup as well. Hope that helps,
