I am writing a test class and am having trouble getting a mthod to test correctly.  The method looks at a couple of parameters and I am not sure how to pass the parameters to the method through my test class.  Can anyone help me?

I need to pass the SelectBox = True and the Participated = false paramerters to this method.  
    public pageReference saveContacts(){
     List<eventRelation> addeventRelation = new List<eventRelation>();
     for(cContacts c: getTeamMember()){
        IF(c.selectBox ==  true && c.participated == false){
            eventRelation ev = new eventRelation();
            ev.RelationId =  c.cId;
            ev.eventId =  eId;
            addeventRelation.add(ev);
     }
    }
    insert addeventRelation;
    pageRef.setRedirect(true);
    return pageRef;
    }
My test method.
 PageReference page = new PageReference('/apex/EventTeamMemberSelection?scontrolCaching=1&id=' + testEvent.Id);
        Test.setCurrentPage(page);
        Test.StartTest();
        ApexPages.StandardController stdCont = new ApexPages.StandardController(testEvent);
        EventTeamMemberSelection extCont = new EventTeamMemberSelection(stdCont); 
        pageReference addCon = extCont.saveContacts();
        pageReference delCon = extCont.deleteContacts();
        Test.StopTest();
