How to query OpportunityHistory in apex test class

Hi Experts,

I am not able to query the opportunity history in a test class. If I tried to query the history, it returns null values. Please let me know how to use the opportunity history object in apex test class.

Thanks,
Vijay

use seeAllData=true. Only then you will get history record. Let us know if this will work

Hi Amit, 

Is there any alternative option without using seeAllData = true option in test class?

Hi Vijay,

I have try the same thing rigth now. And the conclusion is you can not query the OpportunityHistory without SeeAllData = true. Try my code once with SeeAllData = true and then SeeAllData = false and check the Debug you can easily understand what is happening behind.
  
@isTest
public class testCls{
    static testMethod void validateHelloWorld(){
        Account testAcct = new Account (Name = 'My Test Account');
        insert testAcct;
 
        Opportunity oppt = new Opportunity(Name ='New mAWS Deal',
                            AccountID = testAcct.ID,
                            StageName = 'Qualification',
                            Amount = 3000,
                            CloseDate = System.today()
                            );

        insert oppt;
        oppt.StageName = 'Closed Won';
        oppt.Amount = 5000;
        Update oppt;
        list<opportunity> lstOpp = [select id, (select id from OpportunityHistories) from Opportunity where id=:oppt.id];
        system.debug('lstOpp: ' + lstOpp);  
        system.debug('lstOpp: ' + lstOpp[0].OpportunityHistories);  
        
        list<OpportunityHistory> oppHistoryLst = [SELECT Id, OpportunityId, CreatedById, CreatedDate, StageName, 
                                                Amount, ExpectedRevenue, CloseDate, Probability, ForecastCategory, 
                                                SystemModstamp, IsDeleted FROM OpportunityHistory where OpportunityId =:oppt.id];
        system.debug('oppHistoryLst: ' + oppHistoryLst);
    }
}
