Selenium IDE导出与Test :: Unit和Ruby奇怪地工作

Question

我是 Selenium 的新手，我认为 Selenium IDE 可以很好地工作，但是当我导出 Selenium IDE（2.5.0）测试用例到 Ruby Test :: Unit / WebDriver 测试。当我从 Selenium IDE 运行它时，我的测试工作正常，但在导出到 Ruby 之后，以下代码不起作用：

verify { assert_match /.*Welcome/, @driver.find_element(:xpath, "//title").text }

在Selenium IDE上，相同的测试定义为：

命令：verifyText

目标：//title

价值：regexp:.*Welcome

它工作正常（附加屏幕截图）

以下是 Test :: Unit 错误消息：verify { assert_match /.*Welcome/, @driver.find_element(:xpath, "//title").text }因此我猜RegEx存在某种问题。 标题应以“欢迎”一词结尾。

以下代码与代码的一行不同：

require "json"
require "selenium-webdriver"
gem "test-unit" #?
require "test/unit"

class EmployerSignupRuby2 < Test::Unit::TestCase

  def setup
    @driver = Selenium::WebDriver.for :firefox
    @base_url = "http://0.0.0.0:3000/"
    @accept_next_alert = true
    @driver.manage.timeouts.implicit_wait = 30
    @verification_errors = []
  end

  def teardown
    @driver.quit
    assert_equal [], @verification_errors
  end

  def test_employer_signup_ruby2
    @driver.get(@base_url + "/employer_signup")
    @driver.find_element(:id, "employer_first_name").clear
    @driver.find_element(:id, "employer_first_name").send_keys "tester"
    @driver.find_element(:id, "employer_last_name").clear
    @driver.find_element(:id, "employer_last_name").send_keys "login-tester"
    @driver.find_element(:id, "employer_email").clear
    @driver.find_element(:id, "employer_email").send_keys "tester012345678901@test.com"
    @driver.find_element(:id, "employer_password").clear
    @driver.find_element(:id, "employer_password").send_keys "foobar"
    @driver.find_element(:id, "employer_password_confirmation").clear
    @driver.find_element(:id, "employer_password_confirmation").send_keys "foobar"
    @driver.find_element(:name, "commit").click
    verify { assert_match /.*Welcome/, @driver.find_element(:xpath, "//title").text }
  end

  def element_present?(how, what)
    @driver.find_element(how, what)
    #${receiver}.find_element(how, what)
    true
  rescue Selenium::WebDriver::Error::NoSuchElementError
    false
  end

  def alert_present?()
    @driver.find_element(how, what)
    #${receiver}.switch_to.alert
    true
  rescue Selenium::WebDriver::Error::NoAlertPresentError
    false
  end

  def verify(&blk)
    yield
  rescue Test::Unit::AssertionFailedError => ex
    @verification_errors << ex
  end

  def close_alert_and_get_its_text(how, what)
    alert = @driver.switch_to().alert()
    #alert = ${receiver}.switch_to().alert()
    alert_text = alert.text
    if (@accept_next_alert) then
      alert.accept()
    else
      alert.dismiss()
    end
    alert_text
  ensure
    @accept_next_alert = true
  end
end

实际上，当我用这个替换一行代码时，我可以让测试工作（某种程度）：

verify { assert @driver.find_element(:xpath, '//title[contains(.,"Welcome")]') } #works!!

但是如果缺少“欢迎”文本（=测试失败），那么修复将无限期地保持循环，并且我有中断（Ctrl + C）测试。到目前为止，这是我发现的最好的解决方案。如果您知道更好的解决方案，请告诉我，谢谢:-)

我的Gemfile有以下rails / selenium / test版本：

gem 'rails', '4.0.2'
gem 'selenium-webdriver', '~> 2.41.0' #this is the latest version
gem  'test-unit', '2.5.5'
gem 'rake', '10.2.2'

-

$ bundle show json
The gem json has been deleted. It was installed at:
/home/jyrki/.rvm/rubies/ruby-2.1.0/lib/ruby/gems/2.1.0/gems/json-1.8.1

Ruby 2.1.0

此外，导出会创建不起作用的ruby代码：${receiver}.find_element(how, what);所以我需要将其更改为@driver.find_element(how, what)才能使其正常工作。

此外，除了test-unit的require语句（第3-4行）之外，export还会创建一个gem语句：

gem "test-unit" #?
require "test/unit"

我可能会从Selenium Users Google小组以及

询问此问题

顺便问一下，你知道Selenium IDE出口是否比RSpec更好地工作而不是Test :: Unit？
