Question

我在使用capybara-webkit进行集成测试时遇到问题。该问题与使用子域直接相关。

我的所有正常（非JS）集成测试都在运行，但我无法弄清楚如何让它为多租户应用程序工作。我正在使用公寓gem进行多租户，它使用PostgreSQL模式来分割用户数据。用户可以注册，选择子域，然后访问该应用程序。

应用程序设置如下：

在routes.rb中，我有一些限制，具体取决于子域是否存在（查看是否request.subdomain.present?）。如果没有子域存在，则唯一可用的路由是resources :accounts, only: [:new, :create]，否则其他应用程序路由可用。

我的accounts_controller上有一个before_action来调用私有方法load_schema切换到当前子域或重定向到root_url。

def load_schema
  Apartment::Tenant.switch!('public')
  return unless request.subdomain.present?

  if current_account
    Apartment::Tenant.switch!(current_account.subdomain)
  else
    redirect_to root_url(subdomain: false)
  end
end

def current_account
  @current_account ||= Account.find_by(subdomain: request.subdomain)
end
helper_method :current_account

在我的所有RSpec功能规范（当前正在传递的不使用JavaScript）中，我运行了sign_user_in方法来签署用户：

def sign_user_in(user, opts={})
  if opts[:subdomain]
    visit new_user_session_url(subdomain: opts[:subdomain])
  else
    visit new_user_session_path
  end

  fill_in 'user[email]', with: user.email
  fill_in 'user[password]', with: (opts[:password] || user.password)
  click_button 'Log in'
end

我的所有规格都通过了这种方法。

但是，当我使用：js on运行规范时，它永远无法找到'user [email]'。视图使用引导模式弹出创建或编辑操作，然后使用AJAX（通过remote：true）添加或更新页面上新创建的资源。我目前试图通过的一个简单的功能规范是：

require 'rails_helper'

feature 'user creates product' do
  let(:user) { build(:user) }
  let(:account) { create(:account_with_schema, owner: user) }

  scenario 'successfully', :js do
    product = build_stubbed(:product, name: 'Test Product', amazon_sku: 'test_sku', price: 9.99)
    sign_user_in(user, subdomain: account.subdomain)
    click_on 'Products'
    click_on 'New Product'
    fill_in 'product[name]', with: product.name
    fill_in 'product[amazon_sku]', with: product.amazon_sku
    fill_in 'product[price]', with: product.price
    click_on 'Create Product'

    expect(page).to have_content('Test Product')
  end
end

在我的日志中，它显示它正在尝试连接到subdomain1.example.com/users/sign_in：

Received "Visit(http://subdomain1.example.com/users/sign_in)" 
Started "Visit(http://subdomain1.example.com/users/sign_in)" 
Load started 
"Visit(http://subdomain1.example.com/users/sign_in)" started page load 
Started request to "http://subdomain1.example.com/users/sign_in" 
Finished "Visit(http://subdomain1.example.com/users/sign_in)" with response "Success()" 
Received 200 from "http://subdomain1.example.com/users/sign_in"

此子域名1基于我对我的帐户工厂的序列，例如：

factory :account do
    sequence(:subdomain) { |n| "subdomain#{n}" }
...

当然这会失败，因为它无法连接到subdomain1.example.com：

Failures:

  1) user creates product successfully
     Failure/Error: fill_in 'user[email]', with: user.email

     Capybara::ElementNotFound:
       Unable to find field "user[email]"

当我在本地测试时，我使用lvh.me在本地测试子域（因为你不能在localhost上做子域）。

由于我看到了这些错误，因此我将以下内容添加到我的rails_helper.rb中：

Capybara::Webkit.configure do |config|
  config.debug = true
  config.allow_unknown_urls
  config.allow_url("lvh.me")
  config.allow_url("*.lvh.me")
end

但这仍然导致同样的事情。经过一些谷歌搜索，我发现一个问题，提到使用“路径”与“网址”。例如，在我的sign_user_in帮助

中

而不是：

  if opts[:subdomain]
    visit new_user_session_url(subdomain: opts[:subdomain])
  else

使用：

  if opts[:subdomain]
    visit new_user_session_path(subdomain: opts[:subdomain])
  else

当我这样做时，我似乎越来越近了，因为日志现在显示了这个：

Received "AllowUrl(*.lvh.me)" 
Started "AllowUrl(*.lvh.me)" 
Finished "AllowUrl(*.lvh.me)" with response "Success()" 
Wrote response true "" 
Received "Visit(http://lvh.me:3000/users/sign_in)" 
Started "Visit(http://lvh.me:3000/users/sign_in)"

很酷，进步。虽然它不包括子域，即使它正在被传入。另外，这会导致其他5个测试因路由错误而全部失败：

例如：

  5) user authentication does not allow user from one subdomain to sign in on another subdomain
     Failure/Error: visit new_user_session_path(subdomain: opts[:subdomain])

     ActionController::RoutingError:
       No route matches [GET] "/users/sign_in"

即使传入了子域，它也会被忽略，除非有子域，否则该路由不可用。

经过一些谷歌搜索并弄清楚如何为lvh.me设置config.allow_url部分之后，我还发现我应该将它添加到我的development.rb文件中，以便知道端口：

Capybara.always_include_port = true

这是有效的，因为上面的日志输出显示它正在使用端口3000。

接下来，我更改了sign_user_in方法，再次使用访问new_user_session_url（子域名：opts [：subdomain]）（因此我之前的规范仍然会通过）。按照这个SO线程的建议：Capybara with subdomains - default_host我对我的规范进行了调整：

before(:each) do
  set_host "lvh.me:3000"
end

def set_host (host)
  default_url_options[:host] = host
  Capybara.app_host = "http://" + host
end

现在，当我运行规范时，我在日志中看到以下内容：

Received "AllowUrl(*.lvh.me)" 
Started "AllowUrl(*.lvh.me)" 
Finished "AllowUrl(*.lvh.me)" with response "Success()" 
Wrote response true "" 
Received "Visit(http://subdomain1.lvh.me:3000/users/sign_in)" 
Started "Visit(http://subdomain1.lvh.me:3000/users/sign_in)"

Finished "Visit(http://subdomain1.lvh.me:3000/users/sign_in)" with response "Success()" 
Started request to "http://lvh.me:3000/" 
Received 302 from "http://subdomain1.lvh.me:3000/users/sign_in" 
Started request to "http://lvh.me:3000/assets/application.self-e7adbbd6d89b36b8d2524d4a3bbcb85ee152c7a2641271423c86da07df306565.css?body=1"

更多进步！它现在包括子域，端口，并指向端口3000.我仍然得到相同的错误：

  1) user creates product successfully
     Failure/Error: fill_in 'user[email]', with: user.email

     Capybara::ElementNotFound:
       Unable to find field "user[email]"

该SO线程的评论之一是：

“这非常有效。另外，如果您使用的是像lvh.me这样的公共域，您可以使用Capybara.server_port = 31234自动设置端口，然后使用set_host”lvh.me:31234“

所以在我的rails_helper中，我在设置app_host：

的下方添加了server_port

Capybara.app_host = 'http://lvh.me/'
Capybara.server_port = 31234

并将before(:each)更改为使用端口31234.结果相同：

"Visit(http://subdomain6.lvh.me:31234/users/sign_in)" started page load 
Started request to "http://subdomain6.lvh.me:31234/users/sign_in" 
Finished "Visit(http://subdomain6.lvh.me:31234/users/sign_in)" with response "Success()"

Also see this repeated about 100 times (in this and in all previous examples):

但是，唉，得到相同的结果：

Failures:

  1) user creates product successfully
     Failure/Error: fill_in 'user[email]', with: user.email

     Capybara::ElementNotFound:
       Unable to find field "user[email]"

它似乎应该有效，但必须有我遗漏的东西。任何帮助将不胜感激。

从您的日志中看起来您的请求是＆＃34; http://subdomain6.lvh.me:31234/users/sign_in＆＃34;正在重定向到＆＃34; http://lvh.me:31234/＆＃34;如果帐户不存在会发生这种情况。我猜你没有禁用交易测试，这意味着应用程序实际上无法查看测试线程中创建的记录。请参阅 - https://github.com/jnicklas/capybara#transactions-and-database-setup和https://github.com/DatabaseCleaner/database_cleaner#rspec-with-capybara-example
