ruby-on-rails - 使用 Capybara 测试多域 Rails 3 应用程序

Question

我想测试我的多域 RoR3 应用程序。

这是我的 test_helper.rb

ENV["RAILS_ENV"] = "test"

require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'
require 'capybara/rails'
require 'blueprints'

class ActiveSupport::TestCase

end

class ActionDispatch::IntegrationTest
  include Capybara

  def host
    "http://#{subdomain}.lvh.me:3000"
  end

  def subdomain
    @subdomain ? @subdomain : 'demostore'
  end

  def visit(url)
    super("http://#{subdomain}.lvh.me:3000#{url}")
  end
end

还有我的集成测试:

require 'test_helper'

class ProductsTest < ActionDispatch::IntegrationTest

  def setup
    @subdomain = 'demostore'
    # creating stuff
  end

  def teardown
    # deleting stuff
  end

  test "user views product list" do
    visit('/')
    assert page.has_css?('ul.product-listing')
    assert page.has_xpath?("//ul[@class='product-listing']/li", :count => 12)
  end

  test "user views product page" do
    product = Product.first

    visit('/')
    find(:xpath, "//ul[@class='product-listing']/li/a[1]").click
    save_and_open_page
  end

end

我确信该链接存在。单击和填充内容时出现问题。

click_link('Existent link title')

也不起作用。

我认为默认的 Capybara 驱动程序 Rack::Test 可能对这种多域的东西有问题？

Answer 1

在您的设置中，调用此rack::test 函数，这将更改主机的值。嗯，它更改了关于虚假 Web 请求返回的主机。

host! "#{store.subdomain}.example.com"
