Migrating from CamelTestSupport to AbstractCamelTestNGSpringContextTests - apache-camel

Question

I've been using Apache Camel since 3-4 months on Spring 4.0.7.RELEASE
I have several Camel 2.14.0 TestNG tests based on extending CamelTestSupport, in which I use some MockEndpoints.
I configured my routes by overriding the createRouteBuilder() method.
Now I would need also to inject some Spring beans in one of them, by #Autowired annotation.
By reading what is said at http://camel.apache.org/spring-testing.html, I understood that I've to extend AbstractCamelTestNGSpringContextTests now, which supports #Autowired, #DirtiesContext, and #ContextConfiguration.
While I understood that all MockEndpoints are no more accessible by getMockEndpoint() method, but by using #EndpointInject annotation, it is not clear to me is how I can express my routes, because createRouteBuilder() is not more available.
I saw that is possible to define producers and consumers by using annotations, but I cannot manage to understand how routes can be designed.
Many thanks to the community.

Alternatively to the solution given here, you may use the TestNG helper CamelSpringTestSupport in combination with AnnotationConfigApplicationContextif you want to initialize an annotated based Spring configuration context without the need of an additional XML Spring configuration file.
Camel configuration bean class using Spring annotations:
#Configuration
public class MyConfig extends SingleRouteCamelConfiguration {
#Bean
#Override
public RouteBuilder route() {
return new RouteBuilder() {
#Override
public void configure() throws Exception {
from("direct:test").to("mock:direct:end");
}
};
}
}
The TestNG test class extends CamelSpringTestSupport and the Spring configuration MyConfig is initialized with AnnotationConfigApplicationContext:
public class TestNGTest extends org.apache.camel.testng.CamelSpringTestSupport {
#EndpointInject(uri = "mock:direct:end")
protected MockEndpoint errorEndpoint;
#Produce(uri = "direct:test")
protected ProducerTemplate testProducer;
#Override
protected AbstractApplicationContext createApplicationContext() {
return new AnnotationConfigApplicationContext(MyConfig.class);
}
#DirtiesContext
#Test
public void testRoute() throws InterruptedException {
// use templates and endpoints
}
}
