我正在实现一个惰性登录功能。我的黄瓜功能应该描述它：

    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

这些是我的步骤定义：

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

这就是用户登录时发生的情况：cookies.signed[:auth_token]gets 设置。这将由我的 ApplicationController 中的前置过滤器使用，以便打开新浏览器的用户将自动登录：

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

结尾

这是我的 ApplicationController 中的前置过滤器：

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

所以问题是在我的黄瓜功能的最后一步，cookies.signed[:auth_token]返回零。我猜这只是水豚的事情。那么我实际上是否必须在测试中设置一个 cookie 而不是在我的控制器中使用一个？

所以最终我在尝试了很多不同的事情后想通了。

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

更新：

这是我在使用 Selenium 进行某些测试时使用的内容：

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

使用包含驱动程序方法的https://github.com/nruth/show_me_the_cookies 。它具有获取 cookie、删除 cookie 和创建 cookie 的方法，称为create_cookie.

我只需要测试 cookie 值

灵感来自https://collectiveidea.com/blog/archives/2012/01/05/capybara-cucumber-and-how-the-cookie-crumbles

并移植到 Rails 5.x

创造features/support/cookies.rb

有内容

module Capybara
  class Session
    def cookies
      @cookies ||= ActionDispatch::Request.new(Rails.application.env_config.deep_dup).cookie_jar
    end
  end
end

Before do
  allow_any_instance_of(ActionDispatch::Request).to receive(:cookie_jar).and_return(page.cookies)
  allow_any_instance_of(ActionDispatch::Request).to receive(:cookies).and_return(page.cookies)
end

然后是测试步骤

Then('is set cookie {string} with value {string}') do |cookie, value|
  expect(page.cookies.signed[cookie]).to eq value
end
