Hi Team,

I have the following trigger:

trigger UpdateHoursinCase on Case(after insert, after update)

{
  Map<ID, Contract> parentCont= new Map<ID, Contract>();
  List<Id> listIds = new List<Id>();

  for (Case childObj : Trigger.new) {
    listIds.add(childObj.Contract__c);
  }

  parentCont= new Map<Id, Contract>([SELECT id, Hours__c FROM Contract WHERE ID IN :listIds]);

  for (Case Cas: Trigger.new){
     Contract myParentCont = parentCont.get(Cas.Contract__c);
     myParentCont.Hours__c +=   Cas.HoursofWork__c;
  }

  update parentCont.values();
}

which counts hours from the "Child" Case to the Parent Contract.
I works fine.
The Class is:

@istest
public class UpdateLocationStatusonLocationClass{
    Private Static testmethod void TesttrgOnArticulo(){
        Test.startTest();
        Contract  CONT = new Contract ();

        CONT.RecordTypeId  = '012D0000000kZsP';
        CONT.AccountId = '001D0000010dW4H';
//        CONT.AccountId = '001L000000KmBfF';
       
        CONT.CustomerSignedId = '003D0000017D7y8';
//        CONT.CustomerSignedId = '003L000000HQ131';
       
        CONT.Status = 'Draft';   
        String datea = '2000-11-01';
        CONT.StartDate = Date.valueOf(datea);
        CONT.ContractTerm = 9;
      
        insert CONT;
        List<Case>Lstcas=new List<Case>();
        for(integer i=0; i<5; i++){
       
            Case CAS = new Case();
            CAS.Contract__c = CONT.id;
            CAS.Location__c = 'Remote';           
            CAS.Charge__c = 'PER CALL';           
            CAS.AccountId = '001D0000010dW4H';
            CAS.ContactId = '003D0000017D7y8';           
            CONT.Status = 'Closed';
            CAS.Priority= 'EXECUTIVE';           

            Lstcas.add(CAS);
        }
        insert Lstcas;
       
        CONT.RecordTypeId  = '012D0000000kZsP';
        CONT.AccountId = '001D0000010dW4H';
        CONT.CustomerSignedId = '003D0000017D7y8';
        CONT.Status = 'Draft';    
        CONT.StartDate = Date.valueOf(datea);
        CONT.ContractTerm = 9;
       
        update CONT;
       
        Test.stopTest();
    }
}

And it gets only 71% !
Any suggestions to add 4% ?
Best Regards,
Stefanos
