JUnit route with routeContextRef

Hi

I have been trying to JUnit one of my Camel routes where the Camel context
contains a <routeContextRef>. When I comment this out my test works, but I
cannot seem to get my test to run with this in as I get an error,
IllegalArgumentException: Cannot find RouteContext with reference
commonRoute.

How do I either mock or skip this without having to import all the dependent
xml's as I am mocking the endpoint that is dependant on the reference. I am
trying to test just the transform route indicated below.

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:camel="http://camel.apache.org/schema/spring"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://camel.apache.org/schema/spring
http://camel.apache.org/schema/spring/camel-spring.xsd">

<camelContext id="management-mymanagementDetails_v2" trace="{{trace}}"
xmlns="http://camel.apache.org/schema/spring">

<propertyPlaceholder id="properties"
location="/v2/properties/details-v2.properties"/>

<routeContextRef ref="commonRoute"/>

<route id="transform">
<from uri="direct:transform"/>
<marshal ref="jaxbMain"/>
<filter xmlns:ns2="http://www.mycompany/main/management/v2">
<xpath>//ns2:getOrderDetailsRequest</xpath>
<to uri="xquery://v2/xquery/managementRequest.xq"/>
</filter>
<unmarshal ref="jaxbBus"/>
<to uri="direct:toMainServiceCall"/>
</route>

......

Test Class extract, my test is extending CamelSpringTestSupport

@Override
protected AbstractApplicationContext createApplicationContext() {

System.setProperty("trace", "true");
System.setProperty("messageCentralXslt", "messagecentral-transform.xsl");
System.setProperty("msgQueueName", "messagecentral.orderpbb");

ClassPathXmlApplicationContext a = new ClassPathXmlApplicationContext();
*a.setConfigLocations(new String[]{V2_GET_DETAILS_V2_XML});*
return a;
