Subject Re: Need an interceptSendTo hook
Date Fri, 22 Apr 2016 19:03:22 GMT
Awesome, thanks Claus. I switched to using weaveById and got the exact
behavior that I wanted in my actual route (weaveByType could work too but
is a bit less explicit).

For the benefit of others, this is how I'd switch my route DSL from what I
sent earlier:

from("direct:start")
        .setBody().constant(someXml)
        .split().xpath(anXpathExpression)
            .setHeader("myHeader", constant(somethingObtainedFromXpath))
            .id("weaveHere")
            .split().xpath(anotherXpath)
                .to("seda:result");

Then in my test I'd use weaveById("weaveHere").after().to("mock:foo") to
perform my validations.
