How to test redeliver messages?

Hello everybody,

I would like to make sure my redeliver logic is working. I do not find any
feature to do that.
For example, is there anyway to do:

weaveById("ws-call").replace().throwException(new RuntimeException());

This will throw the exception anytime, what if I want to make it fail only
once?

Thanks,
Carl

Hi

You can weave and replace with a mock, and then on the mock endpoint
you can specify that it should throw an exception on the first
message, or the N'th message, with the whenExchangeReceive method.

The Camel in Action book covers this in the testing chapter.

Hey Carl,

you can define a custom processor to throw an exception whenever you want:

weaveById("ws-call").replace().processor(new Processor {
    
    @Override
    void process(Exchange e) {
        // Some custom logic in here to throw an exception
    }
});
