使用@SpringBootTest进行Spring Boot和Camel测试

Question

我有spring boot app，有1.5.8版本的spring boot。 camel 2.20.1

简单路线：

@Component
public class MyRoute extends RouteBuilder {

  public static final String IN = "file://in";

  public static final String OUT = "file://out";

  @Override
  public void configure() throws Exception {
    from(IN).routeId("myId").to(OUT);
  }
}

Und简单测试：

//@SpringBootTest
public class MyRouteTest extends CamelTestSupport {


      @Produce(uri = MyRoute.IN)
      private ProducerTemplate producerTemplate;

      @EndpointInject(uri = "mock:file:out")
      private MockEndpoint mockEndpointOut;

      @Override
      public String isMockEndpoints() {
        return "*";
      }

      @Test
      public void simpleTest() throws Exception {
        mockEndpointOut.expectedMessageCount(1);
        producerTemplate.sendBody("Test");
        mockEndpointOut.assertIsSatisfied();
      }

      @Override
      protected RoutesBuilder createRouteBuilder() throws Exception {
        return new MyRoute();
      }

    }

当我运行此测试时，它运行正常，并且收到一条消息，并且端点满意。如果添加@SpringBootTest注释，则测试失败？为什么呢 当我运行maven clean install时也没有注释，它也会失败:(

任何人都知道此注释对骆驼测试有何作用，或者我如何对其进行调整以使其起作用？

谢谢

Answer 1

这是最后的工作：

@RunWith(CamelSpringBootRunner.class)
@SpringBootTest
@MockEndpoints
public class MyRouteTest2 {

  @Autowired
  private ProducerTemplate producerTemplate;

  @EndpointInject(uri = "mock:file:out")
  private MockEndpoint mockCamel;

  @Test
  public void test() throws InterruptedException {
    String body = "Camel";
    mockCamel.expectedMessageCount(1);

    producerTemplate.sendBody("file:in", body);

    mockCamel.assertIsSatisfied();
  }
}

Answer 2

尝试添加注释@RunWith(CamelSpringBootRunner.class)。根据文档：

实现将功能引入CamelSpringTestSupport基于Spring Boot Test的测试用例的实现。这种方法使开发人员可以使用典型的Spring Test约定对测试开发进行基于Spring Boot的应用程序/路由的测试。

另外，考虑添加@DirtiesContext(classMode = ClassMode.AFTER_EACH_TEST_METHOD)和@DisableJmx(true)。第一个在每种测试方法之后清除Spring Context，这将避免在同一测试用例中其他测试留下的任何后果（例如，显然没有理由失败的测试）。

后面的将禁用JMX，因为您在测试中不需要它。

在官方的文档有大约有春节启动运行Apache骆驼的更多信息。这里有一个摘录的例子：

@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();
    }
}

希望能有所帮助。
