> While implementing a Camel route in a new project which uses Spring's JavaConfig I ran into some issues with tests I had written.
> Originally I implemented the tests using the old XML-based appContext, then once I had everything working I started converting it all to JavaConfig.  After some research, I found that to do this I had to use
> {code:java}
> @ContextConfiguration(
>         locations = {"blah.EsbConfig", ... },
>         loader = JavaConfigContextLoader.class
> )
> {code}
> Which was fine, except it completely broke the functionality of the @MockEndpoints annotation on my tests.  I tried adding a org.apache.camel.impl.InterceptSendToMockEndpointStrategy bean to my JavaConfig context, but that didn't change anything.  To fix it I ended up making a new (Smart)ContextLoader called CamelSpringDelegatingTestContextLoader, which extends Spring's DelegatingSmartContextLoader and is based on CamelSpringTestContextLoader.  It handles both XML and JavaConfig style Spring configuration, and so far seems to have fixed everything.  
> You must use CamelSpringJUnit4ClassRunner for this to work, and change @ContextConfiguration's "locations" to "classes" (and specify them as Class instances). See example below.
> {code:java}
> @RunWith(CamelSpringJUnit4ClassRunner.class)
> @ContextConfiguration(
>         classes = {TestCamelSpringDelegatingTestContextLoader.TestConfig.class},
>         loader = CamelSpringDelegatingTestContextLoader.class
> )
> @MockEndpoints
> public class TestSomethingWithCamel { ... }
> {code}
