Spring Boot Apache Camel Routes testing

Question

I have a Springboot application, where I have some camel routes configured.

public class CamelConfig {
private static final Logger LOG = LoggerFactory.getLog         


        

Answer 1

This is how I did this finally

@RunWith(SpringRunner.class)
public class CamelRouteConfigTest extends CamelTestSupport {

    private static final Logger LOG = LoggerFactory.getLogger(CamelRouteConfigTest.class);
    private static BrokerService brokerSvc = new BrokerService();

    @Mock
    private QueueEventHandler queueEventHandler;

    @BeforeClass
    //Sets up a embedded broker.
    public static void setUpBroker() throws Exception {
        brokerSvc.setBrokerName("TestBroker");
        brokerSvc.addConnector("tcp://localhost:61616");
        brokerSvc.setPersistent(false);
        brokerSvc.setUseJmx(false);
        brokerSvc.start();
    }

    @Override
    protected RoutesBuilder createRouteBuilder() throws Exception {
        return new CamelConfig().route();
    }

    // properties in .yml has to be loaded manually. Not sure of .properties file
    @Override
    protected Properties useOverridePropertiesWithPropertiesComponent() {
        YamlPropertySourceLoader loader = new YamlPropertySourceLoader();
        try {
            PropertySource applicationYamlPropertySource = loader.load(
                "properties", new ClassPathResource("application.yml"),null);// null indicated common properties for all profiles.
            Map source = ((MapPropertySource) applicationYamlPropertySource).getSource();
            Properties properties = new Properties();
            properties.putAll(source);
            return properties;
        } catch (IOException e) {
            LOG.error("application.yml file cannot be found.");
        }

        return null;
    }

    @Override
    protected JndiRegistry createRegistry() throws Exception {
        JndiRegistry jndi = super.createRegistry();
        MockitoAnnotations.initMocks(this);
        jndi.bind("queueEventHandler", queueEventHandler);

        return jndi;
    }

    @Test
    // Sleeping for a few seconds is necessary, because this line template.sendBody runs in a different thread and
    // CamelTest takes a few seconds to do the routing.
    public void testRoute() throws InterruptedException {
        template.sendBody("activemq:productpushevent", "HelloWorld!");
        Thread.sleep(2000);
        verify(queueEventHandler, times(1)).handleQueueEvent(any());
    }

    @AfterClass
    public static void shutDownBroker() throws Exception {
        brokerSvc.stop();
    }
}
