Batch Apex - testing problem

 global class BatchMerger implements Database.Batchable<SObject>{
	

 	private final String query;
	
	global BatchMerger(String q){query = q;}
	
	global database.querylocator start(Database.BatchableContext BC){return Database.getQueryLocator(query);}
	
	global void execute(Database.BatchableContext BC, Sobject[] scope){
		
	Map <Id, Account> dupes = new Map <Id, Account>();
	
	for(sobject s : scope){
	    Account a = (Account)s;
	    dupes.put(a.Id, a);
	}
	
	// Look for dupes Contacts
	List <Contact> contacts = new List <Contact>();
	for(Contact c : [select Id, AccountId from Contact
			          where AccountId in :dupes.keySet()]){
			
	        c.AccountId = dupes.get(c.AccountId).Real_Acct__c;
		contacts.add(c);
	}
		
	// updates
	Database.Saveresult[] src=Database.update(contacts);
		
	}
	
	global void finish(Database.BatchableContext BC){
		
	}
}
 
I have above simple batch to reparent account contacts. It works ok, but in the testing I am not able to get assertions to succeed.
 
 
TEST DATA CREATIONS...

 
...

String query = 'select Id, Real_Acct__c, dupe__c '
		+'from Account '
		+'where Real_Acct__c != null '
		+'and dupe__c = true '
		+'limit 200';

		BatchMerger cln = new BatchMerger(query);
		Id batchProcessId = Database.executeBatch(cln);
			
		Test.StopTest();
		AsyncApexJob[] jobs = [select TotalJobItems, Status, Id from AsyncApexJob where Id = :batchProcessId];
		system.assertEquals(1, jobs[0].TotalJobItems);  <-- THIS IS OK!
                system.assertEquals(0, [select count() from Opportunity where AccountId = :dupes[0].Id]);  <-- THIS FAILS, actual being 1 - the one opp in that in test data was assigned to this account dupes[0].
 
 Can anyone see what's wrong here ?
 
Thanks for help!
