父母们，和你的孩子谈谈 ruby​​ 中的类变量。在别人做之前。

编辑：为用户创建步骤添加了场景和代码。

我正在努力测试一个旧的遗留代码库，在使用 cucumber 时遇到问题。

系统中有“患者”、“站点”和“管理员”用户。有些测试要求您使用患者登录，其他测试要求您使用站点、管理员等登录。当我仅使用已登录的患者运行功能时，它们都可以工作。当我只使用登录的站点用户运行这些功能时，它们都可以工作。当我只使用登录管理员运行功能时，它们都可以工作。当我尝试对多种类型的用户运行混合功能时，第二种和第三种用户的功能不起作用。

我发现的一个线索是，它似乎将所有用户都视为在测试运行中首先登录的用户类型。

这是站点用户的示例测试

  Background:
    Given that I am an "site" user

  Scenario: Patients compliance report page
    When I have patient "Joel" with "4" missed days in diary
    And I go to compliance report page
    Then I should see "Patient Compliance Report"
    And I should see columns
      | Site #/Investigator |
      | Patient             |
      | Registration Date   |
      | Compliance %        |

后台步骤调用以下方法：

def create_and_login_as_role(role)
  role_sym = :"#{role}_user"
  diary = FactoryGirl.create :diary
  study = FactoryGirl.create :study
  site = FactoryGirl.create :site, study: study
  user = FactoryGirl.create role_sym, diary: diary, organization: site
  login user.username, DEFAULT_PASSWORD
end

def login(username, password)
  visit destroy_user_session_path # kills any session, then defaults to login
  fill_in 'user[username]', with: username
  fill_in 'user[password]', with: password

  click_on "Sign in"
end

这是第二种情况

Background:
  Given there are two countries
  And there is a region
  Given that I am an "admin" user
  #I have to create 'ted' second because of the stupid hold-on-to-first-user-type bug
  And there is a site user "ted"

Scenario: Creating a site user
  And I visit the "sites" page
  And I click "New Site"
  And I select the first study from the list
  And I select "USA" from "Country"
  And I select "North America" from "Region"
  And I fill in "Site Number" with "234"
  And I fill in "Site Name" with "SiteySiteful"
  And I select "Active" from "Status"
  And I select "ted" from "Investigator"
  And I select "ted" from "Primary Contact"
  And I fill in "password" with "password"
  And I click "Create Site"
  Then I should see "Site was successfully created"

在这种情况下，该错误还有第二种表现形式。如果我首先创建了站点用户（这只是对工厂的调用），它会以站点用户身份登录管理员用户。

这是用户的工厂：

FactoryGirl.define do
factory :user do |u|
  sequence(:email) {|n| "example#{n}@verdacom.com" }
  sequence(:username) {|n| "user#{n}"}
  password "password"
  tmp_password "password"
  country_id 1
  user_state { FactoryGirl.create(:user_state) }
  password_confirmation {|u| u.password}
  first_name { Faker::Name.first_name }
  last_name { Faker::Name.last_name }
  work_phone "0123456789"
  mobile_phone "0123456789"
  timezone "Etc/UTC"
  diary_creation true
  diary { FactoryGirl.create(:diary) }
end

factory :admin_user, :parent => :user, :class => User do |s|
  sequence(:email) {|n| "admin#{n}@verdacom.com" }
  sequence(:username) {|n| "admin#{n}"}
  force_update_password false
  roles { [FactoryGirl.create(:admin_role)] }
end

factory :diary_author, :parent => :user, :class => User do |s|
  diary nil
end

factory :subject_user, :parent => :user, :class => User do |s|
  roles {[FactoryGirl.create(:subject_role)]}
  diary {FactoryGirl.create(:diary_with_registration_entry)}
  # s.organization { |user| user.association :site }
end

factory :site_user, :parent => :user, :class => User do
  sequence(:email) {|n| "site#{n}@verdacom.com" }
  sequence(:username) {|n| "site#{n}"}
  force_update_password false
  roles { [FactoryGirl.create(:site_role)] }
  # organization { |user| user.association :site }
end
end

这是我的gemfile；值得注意的是 rails 3.1.5、devise、mysql2、activeadmin custom fork（不是我的选择）、cancan、guard、cucumber_rails 和 database_cleaner

source 'http://rubygems.org'

gem 'rails', '3.1.5'

gem 'mysql2'
gem 'activeadmin', :path => "vendor/gems/activeadmin-0.3.4", :git => "https://github.com/alexey/active_admin.git", :branch => "0.3.4-stable" #
gem "haml"
gem "rake", ">= 0.9.2"
gem "meta_search", '>= 1.1.0.pre'
gem 'cancan'
gem 'twiliolib'
gem 'paper_trail'
gem 'jquery-rails'
gem 'capistrano'
gem "capistrano-ext"
gem 'seed-fu', '~> 2.1.0'

gem "newrelic_rpm"

gem 'andand'


gem "execjs"
gem "therubyracer"

gem "hoptoad_notifier", '2.3.11'

gem "faker" # need in development and production/staging also


gem 'sass-rails',   '~> 3.1.4'

group :assets do
  gem 'coffee-rails', '~> 3.1.1'
  gem 'uglifier', '>= 1.0.3'
end

group :test do
  gem 'turn', '< 0.8.3'
  gem 'cucumber-rails', require: false
  gem 'factory_girl_rails'
  gem 'launchy'
  gem "timecop" # for time travelling to test "entries" timeframe
  gem "rack-test"
  gem "prawn"   # for pdf test report generation
  gem "webrat" # simulte http interaction with remote service
end

group :test, :development do
  gem "rspec-rails", "~> 2.6"
  gem "shoulda"
  gem "simplecov" # rcov not supported in ruby 1.9

  gem 'capybara-webkit' # for headless testing
  gem 'database_cleaner'

  gem 'debugger'

  gem 'rb-fsevent'
  gem 'spork', '~> 1.0rc'
  gem 'guard'
  gem 'guard-spork'
  gem 'guard-rspec'
  gem 'guard-cucumber'
  gem 'single_test'
end


group :development do
  gem 'rails-footnotes', '>= 3.7.5.rc4'
  gem "rails-erd"
  gem 'pry'
  gem 'pry-rails'
  gem 'redcarpet'
  gem 'quiet_assets'
end

platforms :ruby do
  gem 'rb-readline'
end

这是我对黄瓜的 database_cleaner 设置，这正是他们的 github 自述文件中的内容：

begin
  require 'database_cleaner'
  require 'database_cleaner/cucumber'
  DatabaseCleaner.strategy = :truncation
rescue NameError
  raise "You need to add database_cleaner to your Gemfile (in the :test group) if you wish to use it."
end

Before do
  DatabaseCleaner.start
end

 After do |scenario|
   DatabaseCleaner.clean
end

任何帮助，将不胜感激。请询问任何可能相关的文件。

当然，数据库清理器不会重置类变量，因为 f@#$ 谁在 ruby​​ 中使用类变量？
