Spring Boot Apache Camel 路线测试

我已经为下面的apache camel路径编写了一个测试用例,
我相信这只测试从SEDA发送端点到模拟端点的消息传输,但可能不会测试棱镜 Camel 路由。想看看是否如何模拟实际端点-如果可能的话。

package com.sams;

import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.test.junit5.CamelTestSupport;
import org.junit.jupiter.api.Test;

import com.sams.pricing.prism.data.processor.util.Endpoints;

public class CamelRouteTests extends CamelTestSupport {

    
    @Override
    protected RouteBuilder createRouteBuilder() {
        return new RouteBuilder() {
            public void configure() {
                from(Endpoints.SEDA_SEND_ENDPOINT)
                    .to("mock:" +  Endpoints.SEDA_PROCESS_ENDPOINT);
            }
        };
    }

    @Test
    public void testRoute() throws Exception {
        // Set up the expectations for the mock endpoint
        getMockEndpoint("mock:" + Endpoints.SEDA_PROCESS_ENDPOINT).expectedMessageCount(1);

        // Send a message to the seda:sendMessage endpoint
        template.sendBody("seda:sendMessage", "test message");

        // Verify that the mock endpoint expectations are met
        assertMockEndpointsSatisfied();
    }


}
// SEDA Endpoint Stage Event Driven Architecture
    from(Endpoints.SEDA_SEND_ENDPOINT)
        .messageHistory()
        // Route Name
        .routeId(Endpoints.SEDA_SEND_ENDPOINT)
        .log("${body}")

        // multicast
        .multicast()
        .parallelProcessing() // create parellel threads
        .log("${body}")

        // thread pool
        .threads()
        .executorService(executorService) // specific thread pool
        .log("Camel Route Started Message Processing : - ${body}")

        // content based routing
        .choice()
        .when(
            CommonUtility
                .costIQPredicate) // predicate checking based on the header value to decide the
        // route
     //    .bean(CostIQService.class, "calculatePrice") // // rules engine call
        .bean(CostIQPayloadTransformer.class, "payloadTransformer") // payload transformer

        // multiple consumer
        .to(
            Endpoints.SEDA_PROCESS_ENDPOINT, // consumer 1
            Endpoints.SEDA_PROCESS_ENDPOINT, // consumer 2
            Endpoints.SEDA_PROCESS_ENDPOINT) // consumer 3
        .when(CommonUtility.optimizationPredicate)
        .bean(OptimizationService.class, "calculatePrice")
        .bean(CostIQPayloadTransformer.class, "payloadTransformer")
        .to(
            Endpoints.SEDA_PROCESS_ENDPOINT,
            Endpoints.SEDA_PROCESS_ENDPOINT,
            Endpoints.SEDA_PROCESS_ENDPOINT)
        .when(CommonUtility.markDownPredicate)
        .bean(MarkDownService.class, "calculatePrice")
        .bean(CostIQPayloadTransformer.class, "payloadTransformer")
        .to(
            Endpoints.SEDA_PROCESS_ENDPOINT,
            Endpoints.SEDA_PROCESS_ENDPOINT,
            Endpoints.SEDA_PROCESS_ENDPOINT)
        .when(CommonUtility.pricingPredicate)
        .bean(PricingService.class, "calculatePrice")
        .bean(CostIQPayloadTransformer.class, "payloadTransformer")
        .to(
            Endpoints.SEDA_PROCESS_ENDPOINT,
            Endpoints.SEDA_PROCESS_ENDPOINT,
            Endpoints.SEDA_PROCESS_ENDPOINT)
        .log("Final :- ${body}")
        .end();
  }

其中,SEDA_SEND_ENDPOINT ="seda:发送消息?块满时=真且并发使用者= 100"
并且SEDA_PROCESS_ENDPOINT ="已满时,seda:处理消息?块=真"
曾试图查找嘲笑,但无法找到解决方案,因为这不会测试实际的 Camel 路线。

我认为您不需要在Test类中覆盖createRouteBuilder(),但在测试中,您需要让Camel模拟您感兴趣的端点:

AdviceWith.adviceWith(context, Endpoints.SEDA_PROCESS_ENDPOINT, a -> {
    a.mockEndpoints(Endpoints.SEDA_PROCESS_ENDPOINT));
});

那你可以

getMockEndpoint("mock:" + Endpoints.SEDA_PROCESS_ENDPOINT)...

请参阅有关模拟现有端点的内容。
