Hi,

I need to write test class for wrapper class coverage.

CLASS
----------
public without sharing class OppController {
    
    public OppController() {

    }
private class wrapOpp {
        public Integer index { get; set; }
        public Opportunity opp {get; set;}
        public String error {get; set; } 
        public List<SelectOption> allEquipments {
            get {
                List<SelectOption> Equipments = new List<SelectOption>();
                Equipments = OppUtil.allEquipmentOptions;
                return Equipments;
            }
        }
        
        public List<SelectOption> allNotifyDates {
            get {
                List<SelectOption> NotifyDates = new List<SelectOption>();
                if(opp.Property__c != null) {
                    NotifyDates = OppUtil.allNotifyDateOptions.get(opp.Equipment__c);
                }
                return NotifyDates;
            }
        }

    private wrapOpp(Integer ndx, Opportunity o, String err) {
            index = ndx;
            opp = o;
            error = err;           
        }
    }
  }
 

  TEST CLASS (wrapper line)
  -------------------------------------
 
 public class testOppclass{

 public static testmethod void TestOppMethod(){

  OppController.wrapperOpp Wrapvar = new OppController.wrapperOpp();

}

}

When I declare a variable I am getting error message as

" Type not visible ; OppController.wrapperOpp" on the line "OppController.wrapperOpp Wrapvar = new OppController.wrapperOpp();"

Please help me in identifying the issue.

Thanks,

JBabu.
