无法将 application.prop 添加到 Camel 测试

Question

我不能让我的测试在测试环境中使用 application.propperies，而在 main 上它工作正常。写它找不到这样的属性。我尝试使用 @TestPropertySource(locations="classpath:application.properties") 但没有帮助。还将 application.propperies 添加到 test 文件夹中的资源中。

My project structure

我的测试课：

@RunWith(SpringRunner.class)
@SpringBootTest
//@TestPropertySource(locations="classpath:application.properties")
public class Excercise5to7ApplicationTests extends CamelTestSupport {


    @Override
    protected RouteBuilder createRouteBuilder() {
        return new MyRoute();
    }

    @Before
    public void mockEndpoints() throws Exception {
        AdviceWithRouteBuilder mockKafka = new AdviceWithRouteBuilder() {

            @Override
            public void configure() throws Exception {
                // mock the for testing
                interceptSendToEndpoint("kafka:*")
                        .skipSendToOriginalEndpoint()
                        .to("mock:kafka");
            }
        };
        RouteDefinition myRoute = context.getRouteDefinition("myRoute");
        myRoute.adviceWith(context, mockKafka);
    }

    @Test
    public void testWithRealFile() throws Exception {
        context.start();
        MockEndpoint kafka = getMockEndpoint("mock:kafka");
        kafka.expectedMessageCount(10);
        kafka.assertIsSatisfied();
        context.stop();
    }
    @Override
    protected Context createJndiContext() throws Exception {
        JndiContext context = new JndiContext();
        context.bind("myBean", new MyBean());
        return context;
    }


    @Override
    public boolean isUseAdviceWith() {
        return true;
    }
}

Answer 1

我在测试中加载属性文件时遇到了同样的问题，我覆盖了通过 CamelTestSupport 类提供的受保护方法“useOverridePropertiesWithPropertiesComponent”。例如：

@Override
protected Properties useOverridePropertiesWithPropertiesComponent()
{
  Properties properties = new Properties();
  try
  {
    properties.load(new FileInputStream(
      "./src/test/resources/test.properties"));
  }
  catch (IOException e)
  {
    fail(e.getMessage());
  }

return properties;

}

@CookieSoup 答案的较短变体可能是更新 Camel Context 为 properties 组件。

@RunWith(CamelSpringBootRunner.class)
@ContextConfiguration
@DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD)
public class YourRouterTest extends CamelTestSupport
{
    ...

    @Override
    protected CamelContext createCamelContext() throws Exception
    {
        SimpleRegistry registry = new SimpleRegistry();
        registry.put("beanName", bean);

        CamelContext camelContext = new DefaultCamelContext(registry);
        camelContext.addRoutes(yourRoutes);

        PropertiesComponent pc = new PropertiesComponent();
        pc.setLocation("classpath:application.properties");
        camelContext.addComponent("properties", pc);

        return camelContext;
    }

    ...
}
