HI 

I have tried a lot for below class code coverage but I'm not able to fix that, some can try the below challenges.
I'm facing exact problem in nested for loop(not able to get a code coverage).


Test class:
 

@isTest (SeeAllData = true) 
Public class TestQuoteToOrder{

 
      @isTest(seealldata=true) static void myunittest1(){
      
      Account acc=new Account();
       acc.Name='Njhhjn';
       acc.Industry__c='Energy';
       acc.Activity__c='End User';
       Acc.BillingCountry='Iia';
       Acc.BillingState='Sikkim';
       Acc.BillingCity='dsad';            
       Acc.BillingStreet='dsaf';             
       Acc.BillingPostalCode='453658';         
        
      Insert acc;
       
       opportunity opp=new opportunity();
         
       opp.Name='test 5';
       opp.CloseDate=date.today();
       opp.StageName='Qualification';
       opp.Product_Type__c='Standard Product';
       opp.Accountid=acc.Id;
       
       opp.N_EP_DPI__c='F/17/213';
       opp.Competitor_Name__c='tets';
       opp.CustomerDevelopment__c='Difficult to create any relationship';
       opp.Estimated_Starting_Date_Of_Mass_Producti__c=date.today();
       opp.Date_For_Proto_types__c=date.today();
       
       Insert opp;
       
       
       Quote__c qu=new Quote__c();
     
         qu.Opportunity_Name__c = opp.Id;
         qu.Account_Name__c = acc.Id;
         
         Insert qu;
     
          
       Quote_line_item__c qli=new Quote_line_item__c();
        qli.Name='test';
        qli.Quote1__c = qu.id;
     
       Insert qli;
       
           //List<Quote__c> qu1=new List<Quote__c>(); 
       Quote__c quii=[select Name,Payment_Terms__c,Account_name__c,Or_contact_Email__c,Or_contact_Phone__c,(select Id,Name,Final_Price__c,Asked_Qty__c,Description__c,Client_P_N__c from Quote_Line_Items__r) from Quote__c LIMIT 1];
       
          
          //qu1.add(quii);
                 
       
       
         order__c qu2=new Order__c();
                qu2.Date_of_Order__c=Date.today();
                qu2.Order_To_Street__c='Bore';
                //qu2.Payment_Terms__c=qu1.Payment_Terms__c;
                //qu2.Quote__c=qu1.id;
                qu2.Account__c=qu.Account_name__c;
       
           Insert qu2;
             
  
       
           Order_item__c orli=new Order_item__c();
           
           orli.Name=qli.Name;
           orli.Description__c=qli.description__c;
           orli.price__c=283;
           //orli.order__c=qu1.Name;
           orli.quantity__c=52;
           
           Insert orli;
         
       System.assertEquals(orli,orli);
          
        Integer rowIndex=1;
        //QuoteToOrder controll=new QuoteToOrder(new apexpages.StandardController(qu));
       ApexPages.StandardController sc= new ApexPages.StandardController(qu);
         QuoteToOrder controll=new QuoteToOrder(sc); 
       
       controll.addrow();
       //controll.remove();   
       controll.deleterow();
       controll.Osave();
       
   }
