如何使用具有持久角色的 Cucumber/Factory Girl

Question

我使用db/seeds.rb 用两个永远不会改变的用户角色（“Admin”、“User”）填充我的数据库。但是，当我运行测试时，种子数据不会被继承，结果是错误测试。

当我尝试运行 cucumber 时，出现以下错误：

使用默认配置文件...功能：登录以获取访问权限 到网站的受保护部分 一个有效的用户应该能够 登录

场景：用户未注册# features/users/sign_in.feature:6 未注册：角色 (参数错误)
/Users/x/.rvm/gems/ruby-1.9.2-p180/gems/factory_girl-2.0.0.rc4/lib/factory_girl/registry.rb:15:in find'
/Users/x/.rvm/gems/ruby-1.9.2-p180/gems/factory_girl-2.0.0.rc4/lib/factory_girl.rb:39:in factory_by_name'
/Users/x/.rvm/gems/ruby-1.9.2-p180/gems/factory_girl-2.0.0.rc4/lib/factory_girl/syntax/vintage.rb:53:in default_strategy'
/Users/x/.rvm/gems/ruby-1.9.2-p180/gems/factory_girl-2.0.0.rc4/lib/factory_girl/syntax/vintage.rb:146:in Factory'
/Users/x/rails/ply_rails/features/support/db_setup.rb:6:in '之前' 鉴于我没有登录# 特征/step_definitions/user_steps.rb:36

这是我的设置：

# features/support/db_setup.rb
Before do
  # Truncates the DB before each Scenario,
  # make sure you've added database_cleaner to your Gemfile.
  DatabaseCleaner.clean

  Factory(:role, :name => 'Admin')
  Factory(:role, :name => 'User')
end



# features/users/sign_in.feature
Feature: Sign in
  In order to get access to protected sections of the site
  A valid user
  Should be able to sign in

    Scenario: User is not signed up  # THIS IS LINE 6
      Given I am not logged in
      And no user exists with an email of "user@user.com"
      When I go to the sign in page
      And I sign in as "user@user.com/password"
      Then I should see "Invalid email or password."
      And I go to the home page
      And I should be signed out



# features/step_definitions/user_steps.rb
Given /^I am a "([^"]*)" named "([^"]*)" with an email "([^"]*)" and password "([^"]*)"$/ do |role, name, email, password|
  User.new(:name => name,
            :email => email,
            :role => Role.find_by_name(role.to_s.camelize),
            :password => password,
            :password_confirmation => password).save!
end

不知道从哪里开始进行这项工作，感谢您的帮助/时间！

Answer 1

嗯，测试的重点是从一个干净的数据库开始，即一致的状态，所以一切都被擦除是件好事。

其次，就黄瓜而言，您应该定义一个背景块来进行设置。这将针对每个场景运行，并具有明确知道每个操作的好处。如果您使用黄瓜场景纯文本显示给客户，这将特别有用。所以你应该这样做：

Background:
    Given that the role "Admin" exists
    And that the role "User" exists

Scenario:
    etc

并为 that the role [blank] exists 创建自定义步骤，为您创建角色。
