functino 呼び出しが行われたときにスパイを使用して監視しようとしています。ただし、コードで動作させることはできません。

私のテスト

            it("calls the totalBogof() function", function() {
                spyOn(basket(), "totalBogof");
                basket().total();
                expect(basket.totalBogof).toHaveBeenCalled();
            });

私がテストしようとしているコード:

basket.prototype = {
    total: function(){
       var total=0.00;
       for(var i=0; i<shoppingBasket.length; i++){
            total += shoppingBasket[i].price;  
        }
         $('#total').html('total = '+currency+total.toFixed(2));
         this.totalBogof(total);
    },
    totalBogof: function(total){
         totalMinBOGOF = total - this.calcBOGOF();
         $('#total-bogof').html('Total - BOGOF = ' + currency + totalMinBOGOF.toFixed(2));
         this.totalPercentageDiscount(totalMinBOGOF, 10);
    },
}

私が得ているエラーはこれです：

これを修正するために私がする必要があるアイデアはありますか?

これを試しましたか？スパイのドキュメントを見てください 

it("calls the totalBogof() function", function() {
   spyOn(basket, "totalBogof");
   basket.total();
   expect(basket.totalBogof).toHaveBeenCalled();
});
