如何引用Capybara驱动程序以创建我的PageObjects/Specs

Question

我试图与Capybara规格一起使用PageObjects，但似乎无法正确地引用驱动程序。基本上，我希望能够使用PageObject来定义页面上的字段(这是login_page.rb(，但是当我尝试在规格中创建对象时，它会丢弃错误，说该对象为nil。

spec_helper.rb ：

# frozen-string-literal: true
require 'rspec'
require 'capybara/rspec'
require 'capybara/dsl'
require 'selenium-webdriver'
require 'page-object'

# loading page object files
page_paths  = File.join(Dir.pwd, 'spec', 'pages', '**', '*.rb')
puts 'foo'
Dir.glob(page_paths).each { |file| puts file}
Dir.glob(page_paths).each { |file| require file }
Capybara.register_driver :firefox do |app|
  Capybara::Selenium::Driver.new(app, browser: :firefox)
end
Capybara.default_driver = :firefox
Capybara.app_host = *********** #redacted
Capybara.default_max_wait_time = 5
RSpec.configure do |config|
  config.before(:all) do
    @browser =  Capybara::Selenium::Driver
  end
  config.before(:each) do
    config.include Capybara::DSL
  end
end

login_page.rb

class LoginPage
  include Capybara::DSL
  include PageObject
  text_field(:username, id: 'username')
  text_field(:password, id: 'password')
  button(:login, id: 'loginButton')
  def initialize(driver)
    @driver = driver
  end
end

login_spec.rb

require 'spec_helper'
describe 'On Login page' do
  context 'using proper password' do
    before(:each) do
      visit('/')
    end
    it 'logs in as foo' do
      login_page = LoginPage.new(@browser)
      login_page.username = 'foo'
      login_page.password = 'bar'
      login_page.login
    end
  end
end

假设您在谈论page-object GEM -https://github.com/cheezy/page-object-不支持辣椒硒 - 韦布驱动器。另外，Capybara::Selenium::Driver是类而不是对象实例。如page-object REDME所示，您需要将对象实例传递到页面对象constructor

@browser = Selenium::WebDriver.for :firefox

如果您想要一个支持Capybara的页面对象框架，则可能需要查看site-prism之类的东西。
