Re: Unit test camel with activeMQ

[hbellat]

I followed some examples in camel-jms package but still have problem.

I wrote my camel.xml 

beans
   xmlns=http://www.springframework.org/schema/beans;
   xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance;
   xsi:schemaLocation=http://camel.apache.org/schema/spring
http://camel.apache.org/schema/spring/camel-spring.xsd
   http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd;

camelContext id=camel xmlns=http://camel.apache.org/schema/spring;

packageScan
   packageorg.foo.bar/package
/packageScan

route
  from uri=activemq:start/
  bean ref=MyBean method=route /
   to uri=activemq:finish/
/route
/camelContext
bean id=mybean class=com.testBeans.MyBean /
bean id=activemq
class=org.apache.activemq.camel.component.ActiveMQComponent 
property name=connectionFactory
  bean class=org.apache.activemq.ActiveMQConnectionFactory
property name=brokerURL
value=vm://localhost?create=falseamp;waitForStart=1 /
property name=userName value=${activemq.username}/
property name=password value=${activemq.password}/
  /bean
/property
/bean
/beans



MyBean class still the same in the last post.

I create a class MyBeanTest.java :

public class MyBeanTest  extends CamelTestSupport{


protected MockEndpoint resultEndpoint;
protected String componentName = activemq;
 protected String startEndpointUri;

@Before
public void setUp() throws Exception {
startEndpointUri = componentName + :start;

super.setUp();

resultEndpoint = (MockEndpoint) 
context.getEndpoint(mock:result);
}

protected AbstractXmlApplicationContext createApplicationContext() {
// TODO Auto-generated method stub
return new 
ClassPathXmlApplicationContext(ressource/camel.xml);
}
   

@Test
public void testRoute() throws Exception {
Object requestBody = template.requestBody(startEndpointUri,
toto);
assertEquals(test, requestBody);
}


}


I create the jar and put it in lib directory for activeMQ and I copy the
content of local file camel.xml to the camel.xml in ActiveMQ.

I started ActiveMQ and the unit Test MyBeanTest but I go into an exception:

Unit test camel with activeMQ

[hbellat]

Hello,

I used Junit for java program but I need some examples to understand how it
works in camel with activeMQ

I wrote a simple camel.xml as follow :

camelContext id=camel xmlns=http://camel.apache.org/schema/spring;
route
from uri=activemq:start/
bean ref=MyBean method=route /
to uri=activemq:finish/
/route
/camelContext

and MyBean.java is :

  public class MyBean {


public void route(Exchange message){

 String name = message.getIn().getBody(String.class);
 
 name=test;
 
 message.getOut().setBody(name);
}
}

In my route I send any string like my unit Test, this string received by
the bean and affecte test in my String and route it to activemq:finish.

How can I write a unit test for that simple code ?

In my test I was wondring if my activemq must be started ?

I will appreciate your help.
