Camel单元测试总是失败，我不能解释为什么expected是0，或者如何正确地断言expected
Camel单元测试总是失败，我不能解释为什么expected是0，或者如何正确地断言expected

我让这个带有Apache Camel的rest端点查找来自不同来源的一些值，首先我验证请求，然后根据路径转到不同的路由：
restConfiguration()
.component("servlet")
.bindingMode(RestBindingMode.json)
...
rest("/lookup/{path}")
.consumes(MediaType.APPLICATION_JSON_VALUE)
.produces(MediaType.APPLICATION_JSON_VALUE)
.post().type(LookupRequest.class).outType(LookupResponse.class)
.to("direct:validate-request")
from("direct:validate-request")
.routeId(Constants.ROUTE_VALIDATE_REQUEST)
.to("bean-validator://x")
.process(exchange ->
exchange.getIn().setHeader("lookupType", env.getProperty("lookup.path." + exchange.getIn().getHeader("path", String.class)))
)
.to("bean:lookupValidationService?method=validate(${body}, ${header.lookupType})")
.toD("direct:db-lookup-${header.lookupType}");
from("direct:db-lookup-customer")
.routeId(Constants.ROUTE_CUSTOMER_LOOKUP)
.log(LoggingLevel.DEBUG, CamelRouter.CAMEL_BODY)
...
.to("sql:{{lookup.queries.customer}}?placeholder=~&usePlaceholder=true")
.process(new SqlQueryResultProcessor())
...
.endRest();这是我测试路由的尝试之一：
@ActiveProfiles("test")
@CamelSpringBootTest
@SpringBootTest(classes = LookupServiceApplication.class)
@MockEndpointsAndSkip("log:.*")
@UseAdviceWith
class CameltestingApplicationTests {
@Autowired CamelContext camelContext;
@Autowired ProducerTemplate producerTemplate;
@EndpointInject("mock:direct:db-lookup-customer")
MockEndpoint customerMock;
static List<Map<String, Object>> results = new ArrayList<Map<String, Object>>() {{
add(new HashMap<String, Object>() {{
put("customerName", "Test customer");
}});
}};
@BeforeEach
public void before() throws Exception {
camelContext.setTracing(true);
AdviceWith.adviceWith(camelContext, Constants.ROUTE_CUSTOMER_LOOKUP, routeBuilder -> {
routeBuilder.interceptSendToEndpoint("sql:*").skipSendToOriginalEndpoint().process(e -> e.getIn().setBody(results));
});
}
@Test
public void testReceive() throws Exception {
camelContext.start();
// Expect:
customerMock.expectedMessageCount(1);
// And: the process to set the header
customerMock.expectedHeaderReceived("lookupType", "customer.info");
Map<String, Object> headers = new HashMap<>();
headers.put("path", "customer.info");
Map<String, Object> keywords = new HashMap<>();
keywords.put("customerNumber", 1234678);
LookupRequest request = new LookupRequest();
request.setKeywords(keywords);
// When we send the message
producerTemplate.sendBodyAndHeaders("direct:validate-request", request, headers);
// Everything is satisfied.
Assert.assertNotNull(camelContext.hasEndpoint("direct:db-lookup-customer"));
customerMock.assertIsSatisfied();
}
}这是日志：

您的@MockEndpointsAndSkip("log:.*")只模拟了log端点，并将customerMock注入为mock:direct:db-lookup-customer，但是如果它不在路由中，它如何接收消息呢？
我认为您所需要做的就是以某种方式模拟您的direct:db-lookup-customer，例如在adviceWith中或使用注释
