我具有创建order
的功能规格。 order
具有如下回调:
class Order
belongs_to :site
before_validation :add_call_number
def call_number
self.call_number = self.site.call_number_start
end
end
在规范中,call_number_start
出现NoMethod错误,因为self.site
不存在。
我发现在操作之前在Rspec中创建的Site
根本不存在。换句话说...
require 'rails_helper'
describe "create successfully", type: :feature, js: true do
before do
@site = create(:site)
visit "/orders"
.... # various actions to build an order using the page's form
puts ">>>>>"
puts "site in before action: #{Site.all.size}"
find("#checkoutModal #submit").click()
sleep(1)
end
it "should create" do
expect(Order.all.size).to equal(1)
expect(Order.last.call_number).to equal(@site.call_number_start)
end
end
# controller action that #submit POSTs to
def create
puts ">>>>>"
puts "site in controller create: #{Site.all.size}"
puts ">>>"
puts "site_id from order_params: #{order_params[:site_id]}"
@order = Order.new(order_params)
@order.save if @order.valid?
end
# puts output:
>>>>>
site in before action: 1
>>>>>
site in controller create: 0
>>>
site_id from order_params: 1
我以为这是数据库清理程序的问题,所以我非常认真地去手动将其设置为truncation
方法,如下所示:
# rails_helper.rb
Rspec.configure do |config|
config.use_transactional_fixtures = false
config.before(:each) do
DatabaseCleaner.strategy = :transaction
end
config.before(:each, js: true) do
DatabaseCleaner.strategy = :truncation
end
config.before(:each, truncate: true) do
DatabaseCleaner.strategy = :truncation
end
config.before(:each) do
DatabaseCleaner.start
end
config.after(:each) do
DatabaseCleaner.clean
end
end
如何正确测试此回调?
您创建了一个站点,但未在控制器中对其进行排序。
该站点是否来自Controller中的order_params
?然后在控制器中找出为什么站点不可用。
该网站与订单相关吗?然后需要创建订购站点:
FactoryBot.create(:site, order: order)
