hi,

Please any one help me on this issue

I have a wrapper class and passing the values from main class and i am not able to write a test class for Wrapper class  please any one help me 

Main class Code sample

   public  List<CustForecastWrapper> custForecasts = null;
    public List<CustForecastWrapper> getCustForecasts(){
  
        New_Forecast__c CustFCst=new New_Forecast__c();
        
        CustFCst=[select id,name from new_forecast__c where Region__r.sales_Rep__c=:usr.id limit 1];
        
        List<Product2> ProdLst=new List<Product2>();
        Map<Id,List<Forecast_sku__c>> CustForcstMap = new Map<Id,List<Forecast_sku__c>>();
        Map<Id,List<Forecast_sku__c>> CustForcstMap1 = new Map<Id,List<Forecast_sku__c>>();
        Map<Id,List<Forecast_sku__c>> CustForcstMapLastYear = new Map<Id,List<Forecast_sku__c>>();
        Map<Id,List<Forecast_sku__c>> CustForcstMapLtLastYear = new Map<Id,List<Forecast_sku__c>>();
        Map<Id,Product2> ProdMap = new Map<Id,Product2>();
        List<Forecast_sku__c> ForcastSKULst = new List<Forecast_sku__c>();
          List<Forecast_sku__c> ForcastSKULst1 = new List<Forecast_sku__c>();
        
        Map<Id,new_forecast__c> CustForcstRecMap = new Map<Id,new_forecast__c>();
        
        ProdLst=[SELECT Id, Name FROM Product2 WHERE IsActive = true order by name];
        for(Product2 Prod : ProdLst){
         List<Forecast_sku__c> TempForcst11 = new List<Forecast_sku__c>();

                CustForcstMap1.get(oForcst.sku__c).add(oForcst);
            }

            }
        }
        for(Forecast_sku__c oForcst : ForcastSKULst){
            if(CustForcstMapLtLastYear.containsKey(oForcst.sku__c) && oForcst.Year__c==LtLastYear){

            }
        }
        
        Map<Id,double> PriceMap = new Map<Id,double>();
        PricebookEntry[] PricEntry = [Select UnitPrice,Product2Id From PricebookEntry where Product2Id IN:ProdMap.KeySet()];
        for(PricebookEntry oPB : PricEntry){
            PriceMap.put(oPB.Product2Id,oPB.UnitPrice);
        }
        
        for(Id oId : CustForcstMap.KeySet()){
            CustForecastWrapper oProdFrcstWrap = new CustForecastWrapper(ProdMap.get(oId), Year ,CustFCst,CustForcstMap1.get(oId),CustForcstMap.get(oId),CustForcstMapLastYear.get(oId), CustForcstMapLtLastYear.get(oId));
            if(PriceMap.containsKey(oID)){
                oProdFrcstWrap.skprc = String.ValueOF(PriceMap.get(oID));
                if(oProdFrcstWrap.skprc=='')
                    oProdFrcstWrap.skprc = 'Please add Standard Price to SKU';
            }           
            custForecasts.add(oProdFrcstWrap);            
        }
        
        return custForecasts;
    }

and This is my wrapper class

public class CustForecastWrapper{

   
    
    public CustForecastWrapper(Product2 prod, String year,new_forecast__c nfc1,List<Forecast_sku__c> LFSKU11,List<Forecast_sku__c> LFSKU,List<Forecast_sku__c> LFSKULstYear,List<Forecast_sku__c> LFSKUSecLstYear ){
        
        
    
}

Thanks....
