Question

我最近升级了：

Page Object 1.2.2
Watir-Webdriver 0.9.9
Selenium WebDriver 2.53.0
Firefox 45.8.0

要：

Page Object 2.2.0
Watir 6.3.0
Selenium-Webdriver 3.4.3
Firefox 52.2.0

经过一点点痛苦之后，我终于开始跑步了！虽然有一个小小的障碍。方法#present?，#exists?和#visible?不会返回任何内容，而是会超时。同样，#wait_until，x_element.when_present?和类似的方法都遇到了同样的问题！

这是我的页面对象：

class LoginPage < TeamConnectPage

  MAX_LOGIN_ATTEMPTS = 3

  button :ok, value: /^OK$/i
  button :submit, value: 'Login'
  button :new_session, value: 'New Session'
  link :logout, id: 'LINK_default_logout'
  span :error_message, class: 'texterror'
  text_field :username, name: 'j_username'
  text_field :password, name: 'j_password'

  def login_as(username)
    username = username.to_s
    do_logout if logged_in?
    attempts = 0
    try_login(username)
    while username_element.present?
      fail "#{MAX_LOGIN_ATTEMPTS} logins attempted unsuccessfully for user #{username}" if (attempts+=1) == MAX_LOGIN_ATTEMPTS
      try_login(username)
    end
    if new_session_element.present?
      new_session
      logout_element.when_present(10)
    end
  end

  private

  def try_login(username)
    self.username = username
    self.password = 'test'
    submit
    wait_for_login_submit
  end

  def wait_for_login_submit
    wait_until(10) { !username_element.present? || (username_element.present? && username_element.value.empty?) }
    wait_until(10) { error_message_element.present? || logout_element.present? || new_session_element.present? }
  end

  def do_logout
    logout
  end

  def logged_in?
    logout_element.present?
  end
end

这是我调用页面对象的步骤定义：

def login_role role
  caps = Selenium::WebDriver::Remote::Capabilities.firefox(accept_insecure_certs: true)
  @browser ||= Watir::Browser.new(:firefox, desired_capabilities: caps)
  @browser.driver.manage.window.maximize
  @browser.goto('http://ntdmatters-it4.nwie.net/TeamConnect/login')
  @logged_in_user = User[RoleMapping[role]]
  on_page(LoginPage).login_as(@logged_in_user.userid)
end

这是我的加载顺序：

require 'pry'
require 'active_support'
require 'active_support/core_ext'
require 'chronic'
require 'page-object'
require 'rspec'
require 'watir'
require 'selenium-webdriver'

这就是我得到的错误：

      timed out after 30 seconds, waiting for #<Watir::Anchor: located: false; {
:id=>"LINK_default_logout", :tag_name=>"a"}> to be located (Watir::Exception::UnknownObjectException)
      (eval):1:in `process_watir_call'
      ./features/support/env.src/pages/login_page.rb:48:in `do_logout'
      ./features/support/env.src/pages/login_page.rb:15:in `login_as'
      ./features/step_definitions/login_steps.rb:24:in `login_role'
      ./features/step_definitions/login_steps.rb:2:in `/^I login to Project
with role (.*)$/'

会发生什么事情，脚本会点击#logged_in?方法而只是坐在那里。然后它会超时并给我上面的错误信息。

我无法帮助并想知道这是否是某种配置问题，而且只需要正确加载或者是否存在某种更深陷的陷阱。

编辑：

当我将Selenium记录器级别更改为＆＃39; Info＆＃39;时，我重复了以下30秒：

EDIT2：无论元素是否实际存在，都会发生这种情况。

Watir / Page Object存在方法定时
