无法使用Capybara-webkit登录,但RSpec / Capybara工作正常

标签: ruby-on-rails devise capybara-webkit

我有一个RSpec功能规范,用于测试我的应用的登录信息。当我在带有Capybara的RSpec中运行它时它会通过,但是当我尝试使用Capybara-webkit运行它标记为js: true时,它会失败。这是一个问题,因为我的整个应用程序都在登录后面,如果我无法运行这一点,我不知道如何为应用程序的其余部分执行功能规范。

以下是我的尝试:

  • 安装所有Capybara-webkit依赖项listed here。我在基于ruby:2.3图像构建的Docker容器中运行我的应用程序,该图像是基于Jessie构建的。
  • 设置DatabaseCleaner per this blog post。我的database_cleaner.rb文件位于下方。
  • 使用无头宝石(headless.rb)
  • 像这样运行RSpec:xvfb-run -a bin/rspec spec/features/log_in_spec.rb(与使用Headless正常运行没什么不同)

如何让我的登录规范在Capybara-webkit下运行?我的一些规范需要为JS标记,有些则不会,但是他们都需要用户登录。谢谢。

log_in_spec.rb

require 'rails_helper'

RSpec.feature "Log in", type: :feature do

  scenario "as admin" do
    user = create(:admin)

    # Tried this instead of with Capybara, works with Capybara but not capybara-webkit    
    # login_as user, scope: :user, run_callbacks: false

    visit root_path
    fill_in 'Email', with: user.email
    fill_in 'Password', with: user.password
    find('.btn-primary').click
    expect(page).to have_content('Admin')
  end
end

spec_helper.rb

require 'capybara/rspec'
require 'paperclip/matchers'

RSpec.configure do |config|

  Capybara.javascript_driver = :webkit
  Capybara.app_host = 'https://192.168.99.101'

  config.include Paperclip::Shoulda::Matchers

  config.expect_with :rspec do |expectations|
    expectations.include_chain_clauses_in_custom_matcher_descriptions = true
  end

  config.mock_with :rspec do |mocks|
    mocks.verify_partial_doubles = true
    mocks.verify_doubled_constant_names = true

  config.run_all_when_everything_filtered = true

  config.disable_monkey_patching!

  if config.files_to_run.one?
    config.default_formatter = 'doc'
  end

end

rails_helper.rb

ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)

# Prevent database truncation if the environment is production
abort("The Rails environment is running in production mode!") if Rails.env.production?
require 'spec_helper'
require 'rspec/rails'

require 'capybara/rails'
require 'devise'

Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f }

RSpec.configure do |config|
  config.use_transactional_fixtures = false

  config.filter_rails_from_backtrace!

  config.include Warden::Test::Helpers
  config.before :suite do
    Warden.test_mode!
  end

  config.after :each do
    Warden.test_reset!
  end

# Added headless gem and this code thanks to this post: http://stackoverflow.com/a/28706535/3043668
if ENV['HEADLESS']
  require 'headless'
  headless = Headless.new
  headless.start
  at_exit { headless.stop }
end

规格/支持/ database_cleaner.rb

RSpec.configure do |config|
  config.before(:suite) do
    DatabaseCleaner.clean_with(:truncation)
  end

  config.before(:each) do
    DatabaseCleaner.strategy = :transaction
  end

  config.before(:each, js: true) do
    DatabaseCleaner.strategy = :truncation
  end

  config.before(:each) do
    DatabaseCleaner.start
  end

  config.after(:each) do
    DatabaseCleaner.clean
  end
end

规格/支持/ headless.rb

RSpec.configure do |config|
  config.around type: :feature do |example|
    Headless.ly do
      example.run
    end
  end
end

规格/支持/ capybara.rb

Capybara::Webkit.configure do |config|
  config.debug = true
  config.allow_unknown_urls
  config.timeout = 5
  config.ignore_ssl_errors
  config.skip_image_loading
end

这是我运行测试时debug output from Capybara-webkit的要点。看起来它一遍又一遍地尝试同样的事情。

更新 我删除了Capybara.app_host设置,非JS测试仍然通过,但是当我在capybara-webkit下运行时,我在debig输出中看到了这一点:

Received "Reset()"

undefined|1|SecurityError: DOM Exception 18: An attempt was made to break through the security policy of the user agent.

正在尝试visit("/login")并且它正被重定向到https版本,这使它失败了。我如何让它成功?

  1. 第一个原因是保存程序后的记录c =在普通视图中不保存密码,但在这种情况下似乎是好的:

    user = create(:admin)
    # ...
    user = User.first # wrong way
    #...
    fill_in 'Password', with: 'password'
    
  2. 登录失败的第二个原因是工厂女孩和水豚使用单独的连接,因此在一个会话中创建的数据在另一个会话中不可用。要修复它,请使用单个连接补丁(将其置于规范/支持),如here所述。

这很难。但问题是我在我的application.rb中设置了force_ssl = true,愚蠢地,而不是像普通人一样将它放在production.rb和development.rb中。

我也设置了Capybara-webkit' app_host,事实证明,我不需要这样做。删除之后,运行带调试的capybara-webkit,我发现它正试图从http://localhost:45362/login(或任何端口)重定向到https://localhost:45362/login(注意https!)这导致了DOM 18安全性错误或其他任何问题,这让它变得窒息。我关掉了force_ssl,现在它就像一个冠军。希望这可以帮助你不要撕掉你的头发。
