Dear Camel Guru's
I have a query regarding testing of a Java DSL route and how to effectively=
 mock endpoints.

I have a SpringRouteBuilder (see following) that polls a database table via=
 the hibernate component, with the results being split into individual resu=
lt items which are transformed into an HAPI HL7 Message via a custom proces=
sor before being sent to a HL7 receiver via a Mina2 endpoint.

Having looked over the testing documentation and not seeing an immediately =
obvious answer, my question is, how best to test a routes logic whilst mock=
ing the producer and consumer endpoints (Hibernate and Mina2 respectively) =
without duplicating the route logic in a Junit test?

HL7RouteBuilder
from("hibernate:HibernateModel?consumeDelete=3Dfalse&consumer.query=3DFROM =
HibernateModel WHERE processed =3D 'N'")
.split(simple("body"))
.log(LoggingLevel.DEBUG, "my.logger", "Transforming HibernateModel ${body.i=
d}")
.to("direct:toHL7");

from("direct:toHL7")
.onException(new Class[] { java.lang.Exception.class })
.log(LoggingLevel.ERROR, " my.logger", "Failed to generate ORU^R01 ${body.i=
d} - ${exception.stacktrace}")
.stop()
.end()
.log(LoggingLevel.DEBUG, "my.logger", "Transforming HibernateModel ${body.i=
d} into HLv2 ORU^R01")
.processRef("modelProcessor")
.marshal().hl7(false)
.to("mirthV2StoreOut");

Camel Spring Configuration
<camel:endpoint id=3D"mirthV2StoreOut" uri=3D"mina2:tcp://${listen.host}:${=
listen.port}?codec=3D#hl7codec"/>
<camel:camelContext id=3D"integrationEngineInCamelCtx">
            <camel:routeBuilder ref=3D"HL7RouteBuilder" />
</camel:camelContext>
<bean id=3D"HL7RouteBuilder" class=3D"HL7RouteBuilder" scope=3D"prototype"/=
>

Kind Regards,
Paul
