I am trying to implement entitlements and I have a few chunks of code that I found here on developerforce. The problem is one trigger that I found, I needed to clone it and change it so that it ran after update instead of after insert. I am using both blocks of code. One is 100% covered and the other (the one I changed) is 0% covered. It works perfectly and I would like to push it into our production org, but since it's a trigger I can't deploy it unless it is at least 1% covered. Can anyone help me out here?

Original Block of Code:

trigger completeFirstResponseCaseComment on CaseComment (after insert) {
         
        // Cannot be a portal user
        if (UserInfo.getUserType() == 'Standard'){
            DateTime completionDate = System.now();
            List<Id> caseIds = new List<Id>();
            for (CaseComment cc : Trigger.new){
                // Only public comments qualify
                if(cc.IsPublished == true)
                    caseIds.add(cc.ParentId);
            }
            if (caseIds.isEmpty() == false){
                List<Case> caseList = [Select c.Id, c.ContactId, c.Contact.Email,
                                  c.OwnerId, c.Status,
                                  c.EntitlementId, c.SlaStartDate,
                                  c.SlaExitDate
                               From Case c
                               Where c.Id IN :caseIds];
                if (caseList.isEmpty() == false){
                    List<Id> updateCases = new List<Id>();
                    for (Case caseObj:caseList) {
                        // consider an outbound email to the contact on the case a valid first response
                        if ((caseObj.Status != 'Awaiting Customer Reply')&&
                            (caseObj.EntitlementId != null)&&
                            (caseObj.SlaStartDate <= completionDate)&&
                            (caseObj.SlaStartDate != null)&&
                            (caseObj.SlaExitDate == null))
                            updateCases.add(caseObj.Id);
                    }
                    if(updateCases.isEmpty() == false)
                        milestoneUtils.completeMilestone(updateCases, 'First Response', completionDate);
                }
            }
        }
    }

Here is the code as I have altered it: 

trigger completeFirstResponseCaseCommentUpdateToPublic on CaseComment (after update) {
         
        // Cannot be a portal user
        if (UserInfo.getUserType() == 'Standard'){
            DateTime completionDate = System.now();
            List<Id> caseIds = new List<Id>();
       
            for (CaseComment cc : Trigger.new){
                // Only public comments qualify
               if(cc.IsPublished == true)
                   caseIds.add(cc.ParentId);
            }
            for (CaseComment cc : Trigger.old){
                // Only public comments qualify
                if(cc.IsPublished == true)
                    caseIds.add(cc.ParentId);
            }
            if (caseIds.isEmpty() == false){
                List<Case> caseList = [Select c.Id, c.ContactId, c.Contact.Email,
                                  c.OwnerId, c.Status,
                                  c.EntitlementId, c.SlaStartDate,
                                  c.SlaExitDate
                               From Case c
                               Where c.Id IN :caseIds];
                if (caseList.isEmpty() == false){
                    List<Id> updateCases = new List<Id>();
                    for (Case caseObj:caseList) {
                        // consider an outbound email to the contact on the case a valid first response
                        if ((caseObj.Status != 'Awaiting Customer Reply')&&
                            (caseObj.EntitlementId != null)&&
                            (caseObj.SlaStartDate <= completionDate)&&
                            (caseObj.SlaStartDate != null)&&
                            (caseObj.SlaExitDate == null))
                            updateCases.add(caseObj.Id);
                    }
                    if(updateCases.isEmpty() == false)
                        milestoneUtils.completeMilestone(updateCases, 'First Response', completionDate);
                }
            }
        }
    }
