apachecamelbeans单元测试

Question

我在我的应用程序中使用带Spring boot的Apache Camel。目前我正在进行单元测试。

Java代码

>

DataRoute类

from("direct:getData")
.routeId("getData")
.bean(DataService.class, "processData")
.marshal().json(JsonLibrary.Jackson)
.end();

DataService类

public Data processData() {
    return new Data("Hello World");
}

带有getter、setter和Jackson-toString方法的数据类

private String value;

单元测试

BaseCamelContextUnitText

public abstract class BaseCamelContextUnitTest extends CamelTestSupport
{
     @Autowired
     private DataService dataService;

     @Produce
     private ProducerTemplate producerTemplate;

     public CamelContext getCamelContext() {
         return camelContext;
     } 

     @Override
     protected Context createJndiContext() throws Exception {
         JndiContext context = new JndiContext();
         context.bind("dataService", dataService);
         return context;
     }

     @Test
     public void shouldProcessData() throws Exception {
          RouteDefinition routeDef = getCamelContext().getRouteDefinition("getData");
          routeDef.adviceWith((ModelCamelContext) getCamelContext(), new RouteBuilder() {

             @Override
             public void configure() throws Exception {
                  from("direct:getData")
                    .pipeline("bean:dataService?method=processData");
             }
     });

     getCamelContext().start();

     String responseData = "{"
        + "\"value\":\"Unit test success\""
        + "}";

     Object response = producerTemplate.sendBody("direct:getData",   ExchangePattern.InOut, null);

     ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
((InputStreamCache) response).writeTo(byteArrayOutputStream);

     assertThat(new String(byteArrayOutputStream.toByteArray()), is(responseData));
     }
  }

我怎么嘲弄

   .bean(DataService.class, "processData")

在单元测试中，返回一个模拟数据对象，其默认字符串变量为“unit test success”，然后测试路由是否会返回模拟对象，而不是带有“Hello World”字符串变量的对象？

Answer 1

您可以在您的DataRoute中自动安装DataService，例如

@Component
public class DataRoute extends RouteBuilder {

    @Autowired
    private DataService dataService;

    @Override
    public void configure() throws Exception {
        from("direct:getData")
        .routeId("getData")
        .bean(dataService, "processData")
        .marshal().json(JsonLibrary.Jackson)
        .end();
    }

}

因此，您可以像往常一样模拟DataService。

另一种方法是在路由中使用beanRef（“beanName”、“methodName”）。
