System.NullPointerException: Argument 1 cannot be null

I have created a apex controller in that I calculated

 

 

 List<PManagement__c PM=[select Rep__c,Revenue___c,Quantity___c,Month_Starting__c,Month_Ending__c from PManagement__c where id=:scon.getId()];
    }
   
public pageReference UpdatePerformance(){
   
   if(!PM.IsEmpty()){
      PManagement__c PMD= PM[0];
      list<sales__c> BS=[select SRep__c,Total_Products__c,Total_Sale_Val__c from SMB_Sales__c   where sale_date__c >=:PMD.Month_Starting__c and sale_date__c <=:PMD.Month_Ending__c AND SRep__c=:PMD.Rep__c ];
      if(SMBS.size()!=0){      
           
            for(Sales__c BS1:BS){
                 TotalRev += BS1.Total_sale_Val__c; // I think problem is here TotalRev is incremented with null value..
                 TotalTar += BS1.Total_Products__c;
            }
            
                 PMD.Revenue__c=TotalRev;
                 PMD.Quantity__c=TotalTar;
            Update PMD;   

   return null;
  }

 Now I am writing test case for above controller

ApexPages.StandardController stdcon=new ApexPages.StandardController(PM); 
     RevTarCon Con= new RevTarCon(stdcon);
       Con.UpdatePerformance(); // This generates error 
    }

 I Got System.NullPointerException: Argument 1 cannot be null , error in test class

How I can I solve this problem.. please help me ?

 

for(Sales__c BS1:BS){          
 TotalRev += BS1.Total_sale_Val__c; 
// I think problem is here TotalRev is incremented with null value..
 TotalTar += BS1.Total_Products__c;
)

TotalTar and TotalRev must both be initialized to zero in the constructor as already suggested and ...

 

TotalRev += (BS1.total_sale_val__c != null ? BS1.Total_sale_Val__c : 0);

can you please post the test class code

@isTest
Class TestRevTarCon{
  Static testMethod void Method1(){
  Date mydate= Date.Today();
  pageReference PR=page.Calculate;
  Test.SetCurrentPage(PR);

insert SR;

   ApexPages.StandardController stdcon=new ApexPages.StandardController(PM); 
     RevTarCon Con= new RevTarCon(stdcon);
     System.assert(con!=null);   
     Con.UpdatePerformance(); // This line causing an error.
 
PManagement__c DUP=[select Revenue__c,Quantity__c,Performance_Calculated__c from PManagement__c where id=:PM.id];
   
   System.assert(DUP.Revenue__c==200);
   System.assert(DUP.Quantity__c==3);
  }

}

 This is my test class

Hi,

 

Try initializing in constructor.

TotalTar = 0; before you increment

TotalRev += (BS1.total_sale_val__c != null ? BS1.Total_sale_Val__c : 0);

Thank you for your response....

 

I followed your suggestions there is no error but..... in test case assertion failed due to not updating of Revenue__c,Quantity__c.

System.assert(DUP.Revenue__c==200);
   System.assert(DUP.Quantity__c==3);


I have noticed that in debug log above valules are initalized with zeros. How to get success with assertions,.. my test case is avaible in previous post of this problem....

18:28:56.308 (308388000)|USER_DEBUG|[30]|DEBUG|REVENUE..........................0
18:28:56.308 (308454000)|USER_DEBUG|[31]|DEBUG|QUANTITY.........................0

Your testmethod is inserting SM_Sales__c SObjects but your controller method is reading SMB_Sales__c objects 

 

As an aside, these issues are readily resolvable by using system.debug statements in your controller so you can see variable values
