[英]Rails + Cucumber/Capybara: How to set/retrieve cookies in tests?
我正在实现一个懒惰的登录功能。 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$/) do #<-- Fails here
page.should have_content("Logout")
end
这就是用户登录时发生的情况: cookies.signed[:auth_token]
被设置。 这将由我的 ApplicationController 中的 before 过滤器使用,以便打开新浏览器的用户将自动登录:
class SessionsController < Devise::SessionsController
def create
super
if user_signed_in?
puts 'yesssssss'
session[:user_id] = current_user.id
current_user.remember_me! if current_user.remember_token.blank?
cookies.signed[:auth_token] = {
:value => current_user.remember_token,
:domain => "mysite.com",
:secure => !(Rails.env.test? || Rails.env.development?)
}
puts "current_user.remember_token = #{current_user.remember_token}"
puts 'cookies:'
puts cookies.signed[:auth_token]
end
end
结束
这是我的 ApplicationController 中的 before 过滤器:
def sign_in_through_cookie
logger.info "logging in by cookie"
puts "logging in by cookie"
puts cookies.signed[:auth_token] #<-- PROBLEM: this returns nil.
return true if !current_user.nil?
if !cookies[:auth_token].nil? && cookies[:auth_token] != ''
user = User.find_by_remember_token(cookies.signed[:auth_token])
return false if user.blank?
sign_in(user)
puts 'success'
return true
else
return false
end
end
所以问题是在我的黄瓜功能的最后一步, cookies.signed[:auth_token]
返回 nil。 我猜这只是水豚的事情。 那么我真的必须在测试中设置一个 cookie 而不是在我的控制器中使用一个吗?
所以最终我在尝试了很多不同的事情后想通了。
Given(/^I didn't log out the last time I was on the site$/) 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
使用封装驱动程序方法的https://github.com/nruth/show_me_the_cookies 。 它有获取 cookie 的方法,删除 cookie 的方法,以及创建 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
创建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
