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

For one route with MQ and Spring Boot like this:

    @Component
    public class InboundRoute extends RouteBuilder {
    
      @Override
      public void configure() {
        JaxbDataFormat personDataFormat = new JaxbDataFormat();
        personDataFormat.setContextPath(Person.class.getPackage().getName());
        personDataFormat.setPrettyPrint(true);
        from("direct:start").id("InboundRoute")
            .log("inbound route")
            .marshal(personDataFormat)
            .to("log:com.company.app?showAll=true&multiline=true")
            .convertBodyTo(String.class)
            .inOnly("mq:q.empi.deim.in")
            .transform(constant("DONE"));
      }
    }

I use adviceWith in order to replace the endpoint and use only mocks:

    @RunWith(CamelSpringBootRunner.class)
    @UseAdviceWith
    @SpringBootTest(classes = InboundApp.class)
    @MockEndpoints("mock:a")
    public class InboundRouteCamelTest {
    
      @EndpointInject(uri = "mock:a")
      private MockEndpoint mock;
    
      @Produce(uri = "direct:start")
      private ProducerTemplate template;
    
      @Autowired
      private CamelContext context;
    
      @Test
      public void whenInboundRouteIsCalled_thenSuccess() throws Exception {
        mock.expectedMinimumMessageCount(1);
        RouteDefinition route = context.getRouteDefinition("InboundRoute");
        route.adviceWith(context, new AdviceWithRouteBuilder() {
          @Override
          public void configure() {
            weaveByToUri("mq:q.empi.deim.in").replace().to("mock:a");
          }
        });
        context.start();
    
        String response = (String) template.requestBodyAndHeader("direct:start",
            getSampleMessage("/SimplePatient.xml"), Exchange.CONTENT_TYPE, MediaType.APPLICATION_XML);
    
        assertThat(response).isEqualTo("DONE");
        mock.assertIsSatisfied();
      }
    
      private String getSampleMessage(String filename) throws Exception {
        return IOUtils
            .toString(this.getClass().getResourceAsStream(filename), StandardCharsets.UTF_8.name());
      }
    }

I use the following dependencies: Spring Boot 2.1.4-RELEASE and Camel 2.23.2. The complete source code is available on Github.
