我正在使用RSpec测试我的在线商店应用程序,这就是我正在做的事情:
# spec/controllers/line_items_controller_spec.rb
require 'spec_helper'
describe LineItemsController do
describe "POST 'create'" do
before do
@current_cart = Factory(:cart)
controller.stub!(:current_cart).and_return(@current_cart)
end
it 'should merge two same line_items into one' do
@product = Factory(:product, :name => "Tee")
post 'create', {:product_id => @product.id}
post 'create', {:product_id => @product.id}
assert LineItem.count.should == 1
assert LineItem.first.quantity.should == 2
end
end
end
# app/controllers/line_items_controller.rb
class LineItemsController < ApplicationController
def create
current_cart.line_items.each do |line_item|
if line_item.product_id == params[:product_id]
line_item.quantity += 1
if line_item.save
render :text => "success"
else
render :text => "failed"
end
return
end
end
@line_item = current_cart.line_items.new(:product_id => params[:product_id])
if @line_item.save
render :text => "success"
else
render :text => "failed"
end
end
end
现在的问题是它从来没有将两个具有相同产品的line_items合二为一,因为我第二次进入line_items_controller#create
,current_cart.line_items
是[],我已经运行{{ 1}}让测试通过,任何想法出了什么问题?
答案 0 :(得分:0)
可能是因为你已经删除了控制器的current_cart,它总是返回没有line_items的Factory(:cart)
。
如果您正在测试current_cart本身,也许最好不要将其删除。
此外,@line_item.save
调用是否返回true?
