感谢史蒂文哈曼的这个要点,我得到了它的工作.devise_mail_helpers.rb

module Features
  module MailHelpers

    def last_email
      ActionMailer::Base.deliveries[0]
    end

    # Can be used like:
    #  extract_token_from_email(:reset_password)
    def extract_token_from_email(token_name)
      mail_body = last_email.body.to_s
      mail_body[/#{token_name.to_s}_token=([^"]+)/, 1]
    end

  end
end

我将文件添加devise_mail_helpers.rb到功能规格所在的文件夹中并编写了此规范.

require 'devise_mail_helpers.rb'
include Features
include MailHelpers
describe "PasswordResets" do
  it "emails user when requesting password reset" do
    user = FactoryGirl.create(:user)
    visit root_url
    find("#login_link").click
    click_link "Forgot your password?"
    fill_in "Email", :with => user.email
    click_button "Send instructions"
    current_path.should eq('/users/sign_in')
    page.should have_content("You will receive an email with instructions about how to …

我正在尝试通过使用factorygirl创建用户创建一个注销流程规范,然后使用Devise的sign_in方法对用户进行身份验证,然后使用capybara单击"注销"链接.

当我运行规范时,我得到(在我看来是什么)一个奇怪的错误:

Failures:

  1) Sign out flow successfully redirects to the welcome index (root)
     Failure/Error: Unable to find matching line from backtrace
     NoMethodError:
       undefined method `env' for nil:NilClass

Finished in 0.00226 seconds (files took 3.32 seconds to load)
1 example, 1 failure

这是规格:

require 'rails_helper'

describe "Sign out flow" do

  include Devise::TestHelpers

  describe "successfully" do
    it "redirects to the welcome index (root)" do
      user = create(:user)
      sign_in user


      within '.user-info' do
        click_link 'Sign Out'
      end …

我正在使用FactoryGirl和Faker在我的seeds.rb文件中生成用户对象但由于某种原因,正在创建完全相同的用户并且rake db:seed由于电子邮件唯一性验证而失败.

用户工厂:

#users.rb
require 'faker'

FactoryGirl.define do
  factory :user do
    first_name            Faker::Name.first_name
    last_name             Faker::Name.last_name
    phone                 Faker::PhoneNumber.cell_phone
    email                 Faker::Internet.email
    password              "password"
    password_confirmation "password"
  end
end

和seeds.rb文件中的代码:

#seeds.rb
rand(5..11).times { FactoryGirl.create(:user) }

错误:

ActiveRecord::RecordInvalid: Validation failed: Email has already been taken

如果我打开控制台并使用FactoryGirl.create(:user)我得到相同的结果......相反的对象正在反复创建,即使我只运行Faker::Internet.email几次我会收到几封电子邮件.

工厂女工:

[1] pry(main)> FactoryGirl.create(:user)
...
=> #<User id: 3, first_name: "Osvaldo", last_name: "Wunsch", email: "willy@damore.net", phone: "(912)530-4949 x64848", created_at: "2014-07-31 20:57:27", updated_at: "2014-07-31 20:57:27", encrypted_password: "$2a$10$mxWC7yLYR0m/Sw8MO6Lyru.xuTHCdCEuM9Orx3LXGApF...", reset_password_token: nil, reset_password_sent_at: …

假设我有一个模型user,它对该email字段有唯一性约束

如果我打电话Factory(:user)一切都很好,但是如果我第二次打电话它会因"条目已存在"错误而失败.

我目前正在使用一个简单的帮助程序在创建工厂之前在数据库中搜索现有条目...并调用我通过该帮助程序创建的任何工厂.

它有效,但它并不完全优雅,考虑到我认为这个问题有多常见,我猜这是一个更好的解决方案.那么,工厂女孩是否有一种内置return_or_create的工厂方式,而不仅仅是提前充电create()？如果没有,大多数人如何避免与他们的工厂重复输入？

假设您有以下mongoid文档:

class User
    include Mongoid::Document
    embeds_one :name
end

class UserName
    include Mongoid::Document
    field :first
    field :last_initial

    embedded_in :user
end

你如何创建一个工厂女工厂,初始化嵌入的名字和最后的名字？你也将如何处理这种embeds_many关系呢？

给定两个对象之间的标准has_many关系.举个简单的例子,我们来看看:

class Order < ActiveRecord::Base
  has_many :line_items
end

class LineItem < ActiveRecord::Base
  belongs_to :order
end

我想要做的是生成带有存根行项目列表的存根订单.

FactoryGirl.define do
  factory :line_item do
    name 'An Item'
    quantity 1
  end
end

FactoryGirl.define do
  factory :order do
    ignore do
      line_items_count 1
    end

    after(:stub) do |order, evaluator|
      order.line_items = build_stubbed_list(:line_item, evaluator.line_items_count, :order => order)
    end
  end
end

上面的代码不起作用,因为Rails想要在分配line_items时调用order并且FactoryGirl引发异常: RuntimeError: stubbed models are not allowed to access the database

那么你如何(或者可能)生成一个存根对象,其中has_may集合也是存根的？

我有一个网络服务,为几个不同的客户提供广告.广告的结构因客户端而异,因此,我通过客户名称为我的模型和控制器使用名称空间来区分广告.从高层看,它看起来像这样:

'app/models/client1/ad.rb'

class Client1::Ad < ActiveRecord::Base
  attr_accessible :title, :description
end

'app/models/client2/ad.rb'

class Client2::Ad < ActiveRecord::Base
  attr_accessible :title, :description, :source
end

实际上,这些模型更复杂并且具有关联性,但这不是重点.
我正在使用rspec-rails 2.4.0和factory_girl_rails 1.0.1编写一些单元测试,并且我的所有工厂都运行良好.但是,我无法为命名空间模型定义工厂.我尝试过类似的东西:

Factory.define :client1_ad, :class => Client1::Ad do |ad|
  ad.title       "software tester"  
  ad.description "Immediate opening"
end  

和

Factory.define :client2_ad, :class => Client2::Ad do |ad|
  ad.title       "software tester"  
  ad.description "Immediate opening"
  ad.source      "feed"
end

它没有完成这项工作.我环顾四周,但我看到的每个例子都使用非命名空间的模型.有人有主意吗？任何输入都非常感谢.

我正在尝试使用factory_girl创建一个"用户"工厂(使用RSpec)但是它似乎没有在事务上运行,并且由于测试数据库中先前测试的残余数据而显然失败了.

Factory.define :user do |user|
  user.name                   "Joe Blow"
  user.email                  "joe@blow.com" 
  user.password               'password'
  user.password_confirmation  'password'
end

@user = Factory.create(:user)

我在模型中有一个方法:

class Article < ActiveRecord::Base
  def do_something
  end
end

我还对此方法进行了单元测试:

# spec/models/article_spec.rb
describe "#do_something" do
  @article = FactoryGirl.create(:article)
  it "should work as expected" do
    @article.do_something
    expect(@article).to have_something
  end
  # ...several other examples for different cases
end

一切都很好,直到我发现将此方法转移到after_save回调中更好:

class Article < ActiveRecord::Base
  after_save :do_something

  def do_something
  end
end

现在我对这个方法的所有测试都破了.我必须解决它:

• 没有更具体的调用do_something因为create或save将触发此方法,或者我将遇到重复的数据库操作.
• 更改create到build
• 测试respond_to

• 使用general model.save而不是单独的方法调用model.do_something

  describe "#do_something" do
    @article = FactoryGirl.build(:article)
    it "should work as expected" do
      expect{@article.save}.not_to raise_error …

transient doFactoryBot工厂的目的是什么？

我见过很多以下面的东西开头的工厂.

factory :car do
  owner nil
  other_attribute nil
end
...

我在这个博客上找到了一些信息:http://blog.thefrontiergroup.com.au/2014/12/using-factory-easily-create-complex-data-sets-rails/

但我仍然不完全明白如何以及为什么这样做.我对FactoryBot的体验很小.

任何有使用FactoryBot经验的人都可以分享一些见解吗？
