编写 apache 骆驼测试用例但出现此错误

Question

我正在写一个骆驼路线测试用例，但遇到了这个问题，还包括了骆驼路线。 已调试看起来 object 正在正确流过，但根据我的断言，它似乎失败了......

java.lang.AssertionError: mock://seda:processMessage?blockWhenFull=true 收到的消息计数。 预期：<1> 但实际为：<0>

（以下为骆驼路线）

 ThreadPoolExecutor executor = (ThreadPoolExecutor) Executors.newFixedThreadPool(2);
    ExecutorService executorService =
        MoreExecutors.getExitingExecutorService(executor, 100, TimeUnit.MILLISECONDS);

    throttlingInflightRoutePolicy.setResumePercentOfMax(25);

    // Camel's error handler that will attempt to redeliver the message 3 times
    errorHandler(deadLetterChannel("seda:costIqDeadLetterChannel")
                    .maximumRedeliveries(3)
                    .redeliveryDelay(3000)
    );

    // SEDA Endpoint Stage Event Driven Architecture
    from(Endpoints.SEDA_SEND_ENDPOINT)
        .messageHistory()
        // Route Name
        .routeId(Endpoints.SEDA_SEND_ENDPOINT)

        // multicast
        .multicast()
        .parallelProcessing() // create parallel threads

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

        .choice()
        .when(PrismUtility.costIQPredicate)
        .circuitBreaker()
        .inheritErrorHandler(true)
        .bean(CostIQService.class, PrismConstants.CALCULATE_PRICE) // rules engine call
        .bean(
            CostIQPayloadTransformer.class,
            PrismConstants.PAYLOAD_TRANSFORMER) // payload transformer
        .to(
            Endpoints.SEDA_PROCESS_ENDPOINT // consumer 1
            )
        .endCircuitBreaker()
        .endChoice()

        .log("Final :- ${body}")
        .end();

编辑：

我通过在我的路线中添加“模拟：”修改了 class，如下所示，但是有没有办法绕过这个 go？ 如果我不更改并将“模拟：”值添加到它发送的位置，它似乎没有发送到正确的端点

编辑：

我添加了这段代码 - 尝试在我的测试 class 中使用 adviceWith。我这样调用端点

    getMockEndpoint("mock:"+Endpoints.SEDA_PROCESS_ENDPOINT).expectedBodiesReceived(costIQPayloadString());

但是我收到错误

无法建议路线，因为没有路线

   @Test
    public void testReplaceFrom() throws Exception {
        AdviceWith.adviceWith(context, Endpoints.SEDA_PROCESS_ENDPOINT, a -> {
            a.mockEndpoints("mock:"+Endpoints.SEDA_PROCESS_ENDPOINT);
        });
        }

这是一个带有路线建议的示例。 请注意，您可能需要在测试后进行一些清理以重置数据！

kotlin 中的代码有点旧，但应该明白了：

@SpringBootTest
class YourTest {
    @Autowired
    private lateinit var camelContext: CamelContext

    @Autowired
    private lateinit var template: ProducerTemplate

    // No MockEndpoints

    ...

    @Throws(Exception::class)
    private fun configureMockEndpoint() {
        AdviceWith.adviceWith(
            camelContext,
            "yourRouteId"
        ) { adviceWithRouteBuilder: AdviceWithRouteBuilder ->
            adviceWithRouteBuilder.replaceFromWith("direct:test")
        }
    }

    @Test
    fun yourTest() {
        configureMockEndpoint()
        template.sendBodyAndHeader("direct:test", "Your headers", """
            your content
        """.trimIndent())
        // asserts
        // cleanups
    }

}
