Old value of field on Apex test?

Hi,
I have an Apex class that compares on some methods the current and the old value of fields.
My question is, for example, If I have an Opportunity and change its name, how can I get the old name value from the test class to compare it with the new/current one?
Thanks.

Try like this
  
Opportunity o = new Opportunity();
        o.name = 'Test';
        o.AccountId = a.Id;
        o.StageName = 'Closed Won';
        o.CloseDate = Date.today();
        o.Type = 'New Customers';
        
        insert o;
		
		String oldName = o.Name ; 
		
		o.Name = 'Udpdate' ; 
		
		update o; 
		
		String newName = o.Name ;
