-------------------------------------
I'm working on additions to the spring-boot.adoc page for this, PR to follow shortly. :)

> Key: CAMEL-11687
> URL: https://issues.apache.org/jira/browse/CAMEL-11687
> Project: Camel
> Issue Type: Improvement
> Components: documentation
> Reporter: Kamil
> Priority: Minor
>
> The [Documentation|http://camel.apache.org/spring-boot.html] helps a lot with configuring Camel with SpringBoot but says nothing about how to configure tests, which is not trivial...
> First of all I noticed, that when you don't Autowire CamelContext and return it in:
> {code}
> @Override
> protected CamelContext createCamelContext() throws Exception {
> return camelContext;
> }
> {code}
> you end up in having two contexts, which causes for example that exception:
> {code}
