Hi,

We have an apex class on our organistaion that has a code coverage of 88% (23/26).  The class itself is only 37 lines and the test class is 25 lines.

Apex Class:

public class Enrg_MeterOfferTag_ACL{
    public static integer rec=0;
    public static void taggOS(Set<Id> setOS, Map<Id,Id> mapOS){
        if(rec==0){
            List<Offer_Site__c> listOS=new List<Offer_Site__c>();
            List<Offer_Site__c> updOs=new List<Offer_site__c>();
            listOS=[Select id,Meter_Provided__c,Meter_Read__c from Offer_Site__c where Id in :setOS];
            for(Offer_site__c objOS:listOS){
                if(objOS.Meter_Read__c==null && mapOS.ContainsKey(objOS.Id)){
                    objOS.Meter_Provided__c=true;
                    objOS.Meter_Read__c=mapOS.get(objOS.Id);
                    updOS.add(objOS);
                }
            }
            if(updOS.Size()>0)
                update updOS;
            rec++;   
        }
    }
     public static void taggRej(Set<String> setreg, Map<String,ID> mapreg){
        if(rec==0){
            List<Registrations__c> listreg=new List<Registrations__c>();
            List<Registrations__c> updreg=new List<Registrations__c>();
            listreg=[Select id,Meter_Read_Information__c from Registrations__c where Id in :setreg];
            for(Registrations__c objreg:listreg){
                System.debug(objreg.Id);
                if(mapreg.ContainsKey(String.valueof(objreg.Id).substring(0,15))){
                    objreg.Meter_Read_Information__c=mapreg.get(String.valueof(objreg.Id).substring(0,15));
                    updreg.add(objreg);
                }
            }
            if(updreg.Size()>0)
                update updreg;
            rec++;   
        }
    }
}

Apex Class Test:

@isTest
private class Enrg_MeterOfferTag_ACL_Test {
private static integer rec=0;
    static testMethod void Enrg_MeterOfferTag_ACL_Test_testmethod() {
        offer__c off=new offer__c();
        insert off;
        Offer_Site__c offsite1=new Offer_Site__c(name='offersite1',offer__c=off.id,MPRN__c='23652013036', Meter_Provided__c=true);
        insert offsite1;       
        Meter_Read__c meter1=new Meter_Read__c(Offer_Site_Id__c=offsite1.id,MPRN__c='23652013036');
        insert meter1;
       
    }
    static testMethod void Enrg_MeterOfferTag_ACL_Test_testmethod1() {
       
        offer__c off1=new offer__c();
        insert off1;
        Offer_Site__c offsite2=new Offer_Site__c(name='offersite2',offer__c=off1.id,MPRN__c='23652013036');
        insert offsite2;
        Registrations__c reg=new Registrations__c() ;
        insert reg;    
        Meter_Read__c meter2=new Meter_Read__c(registration__c=reg.id);
        insert meter2;
        //update reg;
    }
}

Does anyone know what I could add in order to have the code coverage as 100% (26/26)?
Any help is much appreciated.

Thanks
