Camel处理器单元/集成测试

Question

我可能完全错过了一些东西,但我无法按照自己的意愿测试我的路线.

我有以下bean:

@Component("fileProcessor")
public class FileProcessor {
   public boolean valid(@Header("customObject) CustomObject customObject,Exchange exchange) throws IOException{
       return false;
}

我有一条路线叫我的豆像这样:

from("direct:validationFile").routeId("validationFile").validate().method("fileProcessor","valid")
        // Other stuff
        .end();

这是我的单元测试,基于我发现的一个例子:

@RunWith(SpringJUnit4ClassRunner.class)
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class})
@ContextConfiguration(locations = { "classpath:/tu-dao-beans.xml" })
public class FileProcessorTest extends CamelTestSupport {

    @EndpointInject(uri = "mock:result")
    protected MockEndpoint resultEndpoint;

    @Produce(uri = "direct:start")
    protected ProducerTemplate template;

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

    @Test
    public void testSendMatchingMessage() throws Exception {
        String expectedBody = "<matched/>";
        resultEndpoint.expectedBodiesReceived(expectedBody);
        template.sendBodyAndHeader(expectedBody, "foo", "bar");
        resultEndpoint.assertIsSatisfied();
    }

    @Test
    public void testSendNotMatchingMessage() throws Exception {
        resultEndpoint.expectedMessageCount(0);
        template.sendBodyAndHeader("<notMatched/>", "foo", "notMatchedHeaderValue");
        resultEndpoint.assertIsSatisfied();
    }

    @Override
    protected RouteBuilder createRouteBuilder() {
        return new RouteBuilder() {
            public void configure() {
//                from("direct:start").filter(header("foo").isEqualTo("bar")).to("mock:result");
                from("direct:start").routeId("validationFile").validate().method("fileProcessor","valid").to("mock:result");
            }
        };
    }
}   

测试失败,因为fileProcessor没有找到,但我很确定我spring context已正确加载,我正在使用相同的beans.xml文件进行dbunit测试,我的DAO组件发现很好......我错过了什么？

编辑:感谢JérémisB的回答,我很容易解决问题.如果有人绊倒我在这里做的是我添加的代码:

@Autowired
private FileProcessor fileProcessor;

@Override
protected JndiRegistry createRegistry() throws Exception {
    JndiRegistry registry = super.createRegistry();
    registry.bind("fileProcessor", fileProcessor);
    return registry;
}

您可以在Spring上看到"如何"测试的官方文档.

在您的示例中,您创建了一个Spring Context,但使用CamelTestSupport:此类创建一个不知道Spring Context的CamelContext.此上下文未看到bean"fileProcessor".

有很多方法可以进行这种测试.使用您已有的代码,最简单的可能是:

• 使用@Autowire在您的测试类中注入fileProcessor
• 覆盖createRegistry并将fileProcessor添加到注册表

您也可以覆盖CamelSpringTestSupport和实施createApplicationContext.另一种方法是将路由定义保存在Spring Bean中(通过xml或RouteBuilder),并注入测试MockEndpoint或ProducerTemplate.
