Rails + Cucumber / Capybara：如何在测试中设置/检索Cookie？

问题描述

我正在实施一个延迟登录功能。我的黄瓜功能应该描述它：

 功能：用户登录
 
场景： $ b由于我没有注销最后一次我在网站
当我去主页
然后我应该自动登录
  

这些是我的步骤定义：

  / ^我没有注销最后一次我在网站$ /）do 
 user = FactoryGirl.create（：user）
访问new_user_session_path 
 fill_in（'user [email] '，with：user.email）
 fill_in（'user [password]'，with：'test123'）
 click_button（'登录'）
 
 Capybara.reset_sessions！ 
 end 
 
当（/ ^我去主页$ /）do 
访问root_path 
 end 
 
然后应该自动记入$ /）do＃<  - 失败
 page.should have_content（Logout）
 end 
  

这是用户登录时会发生的情况： cookies.signed [：auth_token] 设置。这将由我的ApplicationController中的前过滤器使用，以便打开一个新的浏览器的用户将自动登录：

  SessionsController< Devise :: SessionsController 
 
 def create 
 super 
如果user_signed_in？ 
 puts'yesssssss'
 session [：user_id] = current_user.id 
 current_user.remember_me！如果current_user.remember_token.blank？ 
 cookies.signed [：auth_token] = {
：value => current_user.remember_token，
：domain => mysite.com，
：secure => ！（Rails.env.test？|| Rails.env.development？）
} 
 putscurrent_user.remember_token =＃{current_user.remember_token}
 puts'cookies：'
 puts cookies.signed [：auth_token] 
 end 
 end 
  

end

这是我的ApplicationController中的前过滤器：

  def sign_in_through_cookie 
 logger.info通过cookie登录
 puts通过cookie登录
 puts cookies.signed [：auth_token]＃<  -  PROBLEM：this returns nil。 
 return true if！current_user.nil？ 
 if！cookies [：auth_token] .nil？ &&& cookies [：auth_token]！=''
 user = User.find_by_remember_token（cookies.signed [：auth_token]）
如果user.blank返回false？ 
 sign_in（user）
 put'success'
 return true 
 else 
 return false 
 end 
 end 
  / code>返回nil。我猜这只是一个水豚的事情。因此，我实际上必须在测试中设置一个cookie，而不是使用我的控制器中的一个。
解决方案
 给定（/ ^我最后一次没有注销在网站$ /）do 
 user = FactoryGirl.create（：user）
访问new_user_session_path 
 fill_in（'user [email]'，带：user.email）
 fill_in （'user [password]'，with：'test123'）
 click_button（'登录'）
 
 Capybara.current_session.driver.request.cookies。['auth_token' .should_not be_nil 
 auth_token_value = Capybara.current_session.driver.request.cookies。[]（'auth_token'）
 Capybara.reset_sessions！ 
 page.driver.browser.set_cookie（auth_token =＃{auth_token_value}）
 end 
 
当（/ ^我去主页$ /）do 
访问root_path 
 end 
 
然后（/ ^我应该自动记入$ /）do 
 page.should have_content（Logout）
 end 
  
更新：
 
 
 
我使用Selenium进行一些测试：
 如果Capybara.current_session.driver.class == Capybara :: Selenium： ：Driver 
 auth_token = page.driver.browser.manage.cookie_named（'auth_token'）[：value] 
 page.driver.browser.manage.delete_all_cookies 
 page.driver.browser.manage .add_cookie（：name =>auth_token，：value => auth_token）
 else 
输入cookies =＃{Capybara.current_session.driver.request.cookies}
 Capybara .current_session.driver.request.cookies。[]（'auth_token'）。should_not be_nil 
 auth_token_value = Capybara.current_session.driver.request.cookies。[]（'auth_token'）
 Capybara.reset_sessions！ 
 page.driver.browser.set_cookie（auth_token =＃{auth_token_value}）
 end 
  
 
I'm implementing a lazy login feature. My cucumber feature should describe it:
    Feature: User log in

        Scenario: Lazy login
            Given I didn't log out the last time I was on the site
            When I go to the homepage
            Then I should automatically be logged in
And these are my step definitions:
Given(/^I didn't log out the last time I was on the site$/) do
  user = FactoryGirl.create(:user)
  visit new_user_session_path
  fill_in('user[email]', with: user.email)
  fill_in('user[password]', with: 'test123')
  click_button('Sign in')

  Capybara.reset_sessions!
end

When(/^I go to the homepage$/) do
  visit root_path
end

Then(/^I should automatically be logged in$/) do #<-- Fails here
  page.should have_content("Logout")
end
This is what happens when a user logs in: the cookies.signed[:auth_token] gets set. This will be used by a before filter in my ApplicationController so that users who open a fresh browser will be logged in automatically:
class SessionsController < Devise::SessionsController

def create
  super
  if user_signed_in?
    puts 'yesssssss'
    session[:user_id] = current_user.id
    current_user.remember_me! if current_user.remember_token.blank?
    cookies.signed[:auth_token] = {
      :value => current_user.remember_token,
      :domain => "mysite.com",
      :secure => !(Rails.env.test? || Rails.env.development?)
      }
    puts "current_user.remember_token = #{current_user.remember_token}"
    puts 'cookies:'
    puts cookies.signed[:auth_token]
  end
end
end
This is the before filter in my ApplicationController:
def sign_in_through_cookie
  logger.info "logging in by cookie"
  puts "logging in by cookie"
  puts cookies.signed[:auth_token] #<-- PROBLEM: this returns nil.
  return true if !current_user.nil?
  if !cookies[:auth_token].nil? && cookies[:auth_token] != ''
    user = User.find_by_remember_token(cookies.signed[:auth_token])
    return false if user.blank?
    sign_in(user)
    puts 'success'
    return true
  else
    return false
  end
end
So the issue is that in the last step of my cucumber feature, cookies.signed[:auth_token] returns nil. I'm guessing this is just a capybara thing. So do I actually have to set a cookie in the test as opposed to using the one in my controller?
 解决方案 
So eventually I figured it out after trying a lot of different things.
Given(/^I didn't log out the last time I was on the site$/) do
  user = FactoryGirl.create(:user)
  visit new_user_session_path
  fill_in('user[email]', with: user.email)
  fill_in('user[password]', with: 'test123')
  click_button('Sign in')

  Capybara.current_session.driver.request.cookies.[]('auth_token').should_not be_nil
  auth_token_value = Capybara.current_session.driver.request.cookies.[]('auth_token')
  Capybara.reset_sessions!
  page.driver.browser.set_cookie("auth_token=#{auth_token_value}")
end

When(/^I go to the homepage$/) do
  visit root_path
end

Then(/^I should automatically be logged in$/) do
  page.should have_content("Logout")
end
UPDATE:
Here's what I use in case I'm using Selenium for some of the tests:
if Capybara.current_session.driver.class == Capybara::Selenium::Driver
  auth_token = page.driver.browser.manage.cookie_named('auth_token')[:value]
  page.driver.browser.manage.delete_all_cookies
  page.driver.browser.manage.add_cookie(:name => "auth_token", :value => auth_token)
else
  puts "cookies = #{Capybara.current_session.driver.request.cookies}"
  Capybara.current_session.driver.request.cookies.[]('auth_token').should_not be_nil
  auth_token_value = Capybara.current_session.driver.request.cookies.[]('auth_token')
  Capybara.reset_sessions!
  page.driver.browser.set_cookie("auth_token=#{auth_token_value}")
end
