unit testing - Mocking Mule Variables Using JUnit -

for following mule flow, how mock random_var variable using junit?

<flow name="flow1" doc:name="flow1">     <choice doc:name="choice">         <when expression="${random_var} == 'true'">             <logger message="random var true" level="debug" doc:name="logger"/>         </when>         <otherwise>             <logger message="random var false" level="debug" doc:name="logger"/>         </otherwise>     </choice> </flow> 

i think first of need vm-endpoint in order able call test within functional test.

further should have at: http://www.mulesoft.org/documentation/display/current/functional+testing

for programmatically invoking vm-endpoints using unit test. describes how pass payload it.

the func-test use separated set of config file can define separated configuration flow, seems thing looking for. define variable? in application-config.xml? func test allow running flow test config (you can use same config test , running flow in mule app server)
