    Description

      The Documentation 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:

      @Override
protected CamelContext createCamelContext() throws Exception {
	return camelContext;
}

      you end up in having two contexts, which causes for example that exception:

      Also "CamelSpringTestSupport" requires you to implement "createApplicationContext()" which is weird.

      To sum it up - I found this configuration working fine with Camel-spring-boot:

      @ActiveProfiles("test")
@RunWith(CamelSpringBootRunner.class)
@SpringBootTest
@DirtiesContext(classMode = ClassMode.AFTER_EACH_TEST_METHOD)
@DisableJmx(true)
public class MyRouteTest extends CamelTestSupport {

	@Autowired
	private CamelContext camelContext;

	@Override
	protected CamelContext createCamelContext() throws Exception {
		return camelContext;
	}

	@EndpointInject(uri = "direct:myEndpoint")
	private ProducerTemplate endpoint;

	@Override
	public void setUp() throws Exception {
		super.setUp();
		RouteDefinition definition = context().getRouteDefinitions().get(0);
		definition.adviceWith(context(), new RouteBuilder() {
			@Override
			public void configure() throws Exception {
				onException(Exception.class).maximumRedeliveries(0);
			}
		});
	}

	@Override
	public String isMockEndpointsAndSkip() {
        	return "myEndpoint:put*";
	}

	@Test
	public void shouldSucceed() throws Exception {
		assertNotNull(camelContext);
		assertNotNull(endpoint);
		
		String expectedValue = "expectedValue";
		MockEndpoint mock = getMockEndpoint("mock:myEndpoint:put");
		mock.expectedMessageCount(1);
		mock.allMessages().body().isEqualTo(expectedValue);
		mock.allMessages().header(MY_HEADER).isEqualTo("testHeader");
		endpoint.sendBodyAndHeader("test", MY_HEADER, "testHeader");
		
		mock.assertIsSatisfied();
	}
}
