I can't really make a unit test, but I can provide example drl:
Assuming that the rule project contains a guided decision table and a drl
file:
Guided Decision Table producing drl:
rule "guided rule"
when
then
  myFunctionCall(myGlobalList);
end

The drl file:
import java.util.List;
global java.util.List myGlobalList;

function void myFunctionCall(List aList) {
  System.out.println("List contains:"+list);
}

the rules are initiated by calling:
KieSession ksession = ....
List globalList = new ArrayList();
ksession.setGlobal("myGlobalList", globalList);
