How to start a route in Camel test with mocked endpoints

Question

I start with Camel and am having trouble writing a test. My usage example is the same as cfx proxy example. Except that I don't need a "RealWebservice". Now I'm trying to write unit test (not the integration test included in the example) using the annotation approach:

@RunWith(CamelSpringJUnit4ClassRunner.class) @ContextConfiguration(locations = { "classpath:application-context.xml" }) @MockEndpointsAndSkip public class RoutesTest { @Autowired CamelContext camelContext; @EndpointInject(uri = "mock:cxf:bean:cxfEndpoint", context = "camelContext") MockEndpoint cxfEndpoint; @EndpointInject(uri = "mock:log:input", context = "camelContext") MockEndpoint logInputEndpoint; @EndpointInject(uri = "mock:http:realhostname:8211/service", context = "camelContext") MockEndpoint realEndpoint; @EndpointInject(uri = "mock:cxf:bean:cxfEndpoint") ProducerTemplate producer; @Test public void testLeleuxMifidRoute() throws InterruptedException { String body = "<blah/>"; cxfEndpoint.expectedBodiesReceived(body); logInputEndpoint.expectedBodiesReceived(body); realEndpoint.expectedBodiesReceived(body); producer.sendBody(body); MockEndpoint.assertIsSatisfied(camelContext); } } 

CxfEndpoint receives the message , but other endpoints do not have.

The route looks like this (it works when I run it and send a message with SoapUI, obviously I obfuscated ips and beannames in this example):

 <endpoint id="callRealWebService" uri="http://realhostname:8211/service?throwExceptionOnFailure=true" /> <route> <from uri="cxf:bean:cxfEndpoint?dataFormat=MESSAGE"/> <to uri="log:input?showStreams=true"/> <to ref="callRealWebService"/> <to uri="log:output"/> </route> 

What am I doing wrong? All the examples I gave and other questions seem to use "direct: start" or change the production route.

One of the approaches that we have used with success is the availability of different property files for the test and for the main code.

In the context of a camel, we define a property

 <propertyPlaceholder id="properties" location="classpath:META-INF/uri.properties" xmlns="http://camel.apache.org/schema/spring" /> 

In the folder /src/main/resources/META-INF/ we have the uri.properties file for the main code, and /src/test/resources/META-INF/ we have uri.properties for the test.

Your route should be rewritten using the property placeholder instead of the real uri values ​​using the notation {{properties.name}}

 <route> <from uri="{{cxf.bean.cxfEndpoint}}"/> </route> 

core uri.properties will be

 cxf.bean.cxfEndpoint=cxf:bean:cxfEndpoint?dataFormat=MESSAGE 

uri.properties test will be

 cxf.bean.cxfEndpoint=direct:start 

Using this configuration, you can easily test your route.
