Hi all:

   I am using the wizard apec controller from the book, and decided to write a test class I am getting errors all over ...

please help..

System.DmlException: Insert failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, Required fields are missing: [Name]: [Name]

Class.newOpportunityController.save: line 88, column 7 Class.newOpportunityController.hol: line 146, column 8 External entry point

public class newOpportunityController {

   // These four member variables maintain the state of the wizard.  
    
   // When users enter data into the wizard, their input is stored  
    
   // in these variables.   
    
   Account account;
   Contact contact;
   Opportunity opportunity;
   OpportunityContactRole role;


   // The next four methods return one of each of the four member  
    
   // variables. If this is the first time the method is called,  
    
   // it creates an empty record for the variable.  
    
   public Account getAccount() {
      if(account == null) account = new Account();
      return account;
   }

   public Contact getContact() {
      if(contact == null) contact = new Contact();
      return contact;
   }

      return opportunity;
   }

      if(role == null) role = new OpportunityContactRole();
      return role;
   }


   // The next three methods control navigation through  
    
   // the wizard. Each returns a PageReference for one of the three pages  
    
   // in the wizard. Note that the redirect attribute does not need to  
    
   // be set on the PageReference because the URL does not need to change  
    
   // when users move from page to page.
