Hi All 

I have a controller and I am working to deploy it to the server and it says code coverage failed 

I am struggling with the test class. Here is the controller. 

public class PriceBookserna {
    
   public class productInfo {
    
        public Product2 prod{get; set;}
        public List<PriceBookEntry> pbes {get; set;}
                public List<PriceBookEntry> pbef {get; set;}
                                public List<PriceBookEntry> pbea {get; set;}

                                public List<PriceBookEntry> pbeb {get; set;}
                                  // public List<PriceBookEntry> pbec {get; set;}


        public productInfo() {
            pbes = new List<PriceBookEntry>();
                        pbef = new List<PriceBookEntry>();
           pbea = new List<PriceBookEntry>();
           pbeb = new List<PriceBookEntry>();
                     // pbec = new List<PriceBookEntry>();



        }
        
    }
    
    public List<ProductInfo> products {get; set;}

Please help me with the Test Class.
