In general you won't know until you run your code, as you've not shown
any code which adds something to @items. For example:

cart = Cart.new
product = Flurble.new
cart.items << product
cart.add_product(product)

In this case, current_item will be of class Flurble.

Yes, you're right:

def add_product(product)
current_item = @items.find {|item| item.product == product}
if current_item
current_item.increment_quantity
else
@items << CartItem.new(product)
end
end

in my case current_item w'll be of class "CartItem"
Thank you for reply
