Question

非常简单的路线：

import org.apache.camel.builder.RouteBuilder

class TestRoutes extends RouteBuilder {    
  @Override
  void configure(){
    from("direct:foo").to("mock:bar")
  }
}

非常简单的测试用例：

package mocktest

import static org.junit.Assert.*
import org.junit.*

import org.apache.camel.CamelContext
import org.apache.camel.ProducerTemplate
import org.apache.camel.test.junit4.CamelTestSupport

class TestRouteTests extends CamelTestSupport {

  def CamelContext camelContext
  def ProducerTemplate producerTemplate

  @Test
  void testSomething() {

    getMockEndpoint('mock:bar').expectedMessageCount(1)
    producerTemplate.sendBody('direct:foo', "Hello World")

    assertMockEndpointsSatisfied()
  }
}

获取此信息：

| Failure:  testSomething(mocktest.TestRouteTests)
|  java.lang.AssertionError: mock://bar Received message count. Expected: <1> but was: <0>

与骆驼一起尝试：2.12.1，骆驼：2.11.1 今天试图解决问题。完整的测试grails项目仅包含此问题：https://github.com/gutsal-arsen/mocktest

有人可以帮我解决一下吗？

  @Test
  void testSimpleRoute() {
    def mockEndpoint
    mockEndpoint = camelContext.getEndpoint('mock:bar')
    //mockEndpoint = getMockEndpoint('mock:bar')                                                                                                                                                                                               

    mockEndpoint.expectedMessageCount(1)

    producerTemplate.sendBody('direct:foo', 'Hello World')

    mockEndpoint.assertIsSatisfied()
  }

这个没有：

   @Test
  void testSimpleRoute() {
    def mockEndpoint
    //mockEndpoint = camelContext.getEndpoint('mock:bar')
    mockEndpoint = getMockEndpoint('mock:bar')                                                                                                                                                                                               

    mockEndpoint.expectedMessageCount(1)

    producerTemplate.sendBody('direct:foo', 'Hello World')

    mockEndpoint.assertIsSatisfied()
}

所以问题出在getMockEndpoint（）方法中。

要解决此问题，我们应该覆盖CamelTestSupport#createCamelContext方法，因为默认实现创建了单独的camel上下文，它不包含我们的路由（因此，模拟端点是假的）。

像这样：

   protected CamelContext createCamelContext() throws Exception {                                                                                                                         
    return camelContext;
  }

完整的资源现在看起来像：

package mocktest

import static org.junit.Assert.*
import org.junit.*

import org.apache.camel.CamelContext
import org.apache.camel.impl.DefaultCamelContext
import org.apache.camel.ProducerTemplate
import org.apache.camel.test.junit4.CamelTestSupport
import org.apache.camel.builder.RouteBuilder

import org.apache.camel.processor.interceptor.Tracer
import org.apache.camel.processor.interceptor.DefaultTraceFormatter
import org.apache.camel.LoggingLevel

class TestRouteTests extends CamelTestSupport {

  def CamelContext camelContext
  def ProducerTemplate producerTemplate

  protected CamelContext createCamelContext() throws Exception {                                                                                                                         
    return camelContext;
  }

  @Test
  void testSomething() {
    def mockEndpoint
    //mockEndpoint = camelContext.getEndpoint('mock:bar') // this works                                                                                                                  
    mockEndpoint = getMockEndpoint('mock:bar') // this works now also                                                                                                                          

    mockEndpoint.expectedMessageCount(1)
    producerTemplate.sendBody('direct:foo', "Hello World")

    assertMockEndpointsSatisfied()                                                                                             
  }
}

你从未定义过向mock:bar端点发送消息的路由......添加类似这样的内容

@Override
protected RouteBuilder createRouteBuilder() throws Exception {
    return new RouteBuilder() {
        @Override
        public void configure() throws Exception {
            from("direct:foo").to("mock:bar");
        }
    };
}

Camel Mock端点不会收到任何消息
