Mocking Beans
Does Camel have some built in functionality to replace a Bean within a
Route while maintaining the method called on the bean?
For instance, given the RouteBuilder below, I would like to replace myBean
with myMockBean during testing. I've considered using AdviceWith, but that
seams to replace the entire Bean Node rather than just the instance of the
class used by the Bean Node.
public class MyRouteBuilder extends RouteBuilder
{
@BeanInject
private MyBean myBean;
@Override
public void configure() throws Exception
{
from("direct:myEndpoint")
.bean(myBean, "myMethod")
.id("myBeanId");
}
}

Hi
Yeah you can also have getter/setter for the bean and then set a new
bean in the route builder class before starting the test.
Or as suggested by Luiz you can inject other beans from the @Autowried
@BeanInject and what else annotations are there.
And for advice with, you can also use its replace with, and then set
up another node that calls another bean.

Thanks Luiz! Constructor injection should work for us. Just wanted to make
sure there wasn't something built in to Camel!

I confess I'm not familiar with @BeanInject, but if it's similar in purpose
as @Autowired from Spring, then I'd suggest using constructor injection.
That way you can create your object with your mocked bean.
Personally I do it like that in unit testing.
