为什么 Capybara 在一次活动后放弃我的会话? [英] Why is Capybara discarding my session after one event?

问题描述

对于大多数控制器测试具有 before_filter :authenticate_user! 的 rails 应用程序，我无法让 Capybara 保留会话.

Testing a rails application which has before_filter :authenticate_user! for most controllers, I cannot get Capybara to preserve a session.

我使用 PhantomJS 和 poltergeist 配置了 Capybara.

I have Capybara configured using PhantomJS with poltergeist.

我使用以下助手:

require 'spec_helper'
include Warden::Test::Helpers

module FeatureHelpers
  def login(user = FactoryGirl.create(:default_user))
    login_as user, scope: :user
    user
  end
end

我有以下规范文件:

require 'spec_helper'
include Warden::Test::Helpers

feature 'Leads Data Tasks View' do
  before(:each) do
    @user = login
  end

  after{ Warden.test_reset! }

  context "clicking a task button" do
    scenario "login persists across multuple actions", js: true do
      visit '/tasks'

      page.should have_selector('#parse', count: 1)
    end
  end
end

当我按照此处显示的方式运行测试时，它会通过.但是，如果我在执行 AJAX 操作的某些内容上调用 click_link，或者如果我只是尝试执行 visit '/tasks' 两次，应该 断言将失败，因为我将被重定向到应用程序的登录页面.

When I run the test as it's shown here, it will pass. However, if I invoke a click_link on something that performs AJAX actions, or if I simply try to do visit '/tasks' twice, the should assertion will fail because I'll get redirected to the login page of the app.

我尝试了几种不同的方法，包括设置 Capybara::Session，但我仍然收到 AJAX 请求的 401 代码，并且每个规范只能成功访问一次.

I've tried a few different approaches, including setting up a Capybara::Session, but I still get 401 codes on AJAX requests and I can only successfully visit once per spec.

我做错了什么?

推荐答案

所以问题是 phantomjs 驱动程序 (poltergeist) 使用的是分离的数据库连接.我之前遇到过完全相同的问题，我从 railscast 第 391 集 中得到了解决方案，代码为spec/support/shared_db_connection.rb

So the problem was that phantomjs driver (poltergeist) was using a separated database connection. I had the exact same issue before and I got a solution from railscast episode 391 with the code in spec/support/shared_db_connection.rb

因为我找不到他的代码的许可证，所以我只链接到 代码在这里

Since I can't find license for his code so I will just link to the code here
