testing camel quartz job

I try to make a junit test for apache camel route. Something like this :

@RunWith(CamelSpringJUnit4ClassRunner.class)
@ContextConfiguration(
    loader = CamelSpringDelegatingTestContextLoader.class
)
public class MyExportRouteBuilderIT extends CamelTestSupport {
    @Test
    public void test() {
        // trigger and check the files made by route builder processor
    }

    @Override
    protected RouteBuilder createRouteBuilder() throws Exception {
        return new MyExportRouteBuilder();
    }
}

The builder class is defined like this

from("quartz2://exportJob?cron=" + cronTrigger)
.setHeader(FILE_NAME, expression(FILE_NAME_FORMAT))
.process(myExportRouteProcessor)
.marshal(new BindyCsvDataFormat(MyExportData.class))
.to("file:///destination);

The 'myExportRouteProcessor' class just gets some data from the JPA repository and puts the results to the route. What I want is to trigger this job in the test class to check if the whole process was properly finished. Currently, processor is not fired. What should I do more ?
