Hi Community,

I came across the following the situation.

I created an opportunity for the test data and I updated the stage of the opportunity. Expected a value to be changed on the other object.
Sample of my code is as follows.

My issue is in Bold letters. The old map is picking the updated value. where i need to compare old value with new value. but after update the old Map is also takinig new value.
What I am doing wrong.

@isTest
private class opporutnityBusinessLogicTest{

static testmethod void mytestmethod1(){
  Ilist<Account> lstAccount = new list<Account>();
            list<Opportunity> lstOpportunity = new  list<Opportunity>();
            list<PP_OPRTY_PRODT__c> lstOpportunityProd =new list<PP_OPRTY_PRODT__c>();
          
            final string BrokerRecType='Customer';
            schema.describesobjectresult r=account.sobjecttype.getdescribe();
            map<string,schema.recordtypeinfo> m=r.getrecordtypeinfosbyname();
            id brkerRecType= m.get(BrokerRecType).getrecordtypeid();
          
             Integer intNoOfRecord=1;
            for(integer i=0; i < intNoOfRecord; i++){
                account a=new account(Name='Test Customer Account'+i,Broker_Id__c='B99999'+i,PP_ID__c='99999BROKER'+i,Start_Date__c=date.today(),End_Date__c=date.today()+5,recordtypeId=brkerRecType);
                lstAccount.add(a);                
            }
            insert lstAccount;
          
            for(integer i=0;i< intNoOfRecord;i++){
                 Opportunity a=new Opportunity
                                            (CloseDate=date.ValueOf('2015-04-28'),Name='Test Opty ' + i

                                            );
                lstOpportunity.add(a);    
            }
            insert lstOpportunity;

            map<Id,Opportunity> oldMap=new map<Id,Opportunity>();        
            oppMap.put(oppRecId,oppRecord);
