ruby - 如何在 Jenkins 服务器 (Linux) 上运行 Cucumber headless 测试

Question

如何在 Jenkins Server (Linux) 上运行 Cucumber headless 测试？

使用“ headless ”gem 在 Jenkins 上执行 Cucumber/Watir-Webdriver 测试的正确方法是什么？

第一次尝试:我的 env.rb 中有这个:

require 'rubygems'
require 'cucumber'
require 'rest_client'
require 'json'
require 'watir-webdriver'
require 'page-object'
require 'page-object/page_factory'
require 'allure-cucumber'
require 'rspec'
require 'data_magic'
require 'fig_newton'
require 'yaml'
require 'headless'
require 'phantomjs'

ENVT = FigNewton.load('staging.yml')
DATA = DataMagic.load('data.yml')
KBA = YAML.load_file('config/data/kba.yml')

#Actions performed before each scenario

headless = Headless.new
headless.start
browser = Watir::Browser.start

Before do
  @browser = browser
end

at_exit do
  browser.close
  headless.destroy
end

World(PageObject::PageFactory)

这是我得到的输出:

第二次尝试:当我在此行的 env 文件中进行一项更改时:

browser = Watir::Browser.start

到

browser = Watir::Browser.new

然后我得到这个输出，但仍然错误:

Could not find Firefox binary (os=linux). Make sure Firefox is installed or set the path manually with Selenium::WebDriver::Firefox::Binary.path= (Selenium::WebDriver::Error::WebDriverError)
/var/lib/jenkins/.rbenv/versions/2.1.0/lib/ruby/gems/2.1.0/gems/selenium-webdriver-2.45.0.dev3/lib/selenium/webdriver/firefox/binary.rb:127:in `path'

第三次尝试:

如果我将 env.rb 文件更改为:

require 'rubygems'
require 'cucumber'
require 'rest_client'
require 'json'
require 'watir-webdriver'
require 'page-object'
require 'page-object/page_factory'
require 'allure-cucumber'
require 'rspec'
require 'data_magic'
require 'fig_newton'
require 'yaml'
require 'headless'
require 'phantomjs'

ENVT = FigNewton.load('staging.yml')
DATA = DataMagic.load('data.yml')
KBA = YAML.load_file('config/data/kba.yml')

#Actions performed before each scenario

headless = Headless.new
headless.start
# browser = Watir::Browser.start

Before do
  @browser = headless
end

at_exit do
  #browser.close
  headless.destroy
end

World(PageObject::PageFactory)

看起来好多了，但还是失败了:

那么使用“ headless ”gem 在 Jenkins 上执行 Cucumber/Watir-Webdriver 测试的正确方法是什么？

更新:如何使用 Xvfb 和 Watir？

我的环境.rb:

require 'rubygems'
require 'cucumber'
require 'json'
require 'watir-webdriver'
require 'page-object'
require 'page-object/page_factory'
require 'allure-cucumber'
require 'rspec'
require 'data_magic'
require 'fig_newton'
require 'yaml'
require 'phantomjs'
require 'headless'

ENVT = FigNewton.load('staging.yml')
DATA = DataMagic.load('data.yml')
KBA = YAML.load_file('config/data/kba.yml')

headless = Headless.new
headless.start
browser = Watir::Browser.new

Before do
  @browser = browser
end

at_exit do
  @browser.close
end

World(PageObject::PageFactory)

Answer 1

我工作的最后一个地方我们没有使用 headless gem，我们只是在运行测试的 Jenkins 脚本中启动 XVFB，然后它发出启动测试的 cucumber 命令。并使用 Firefox 作为浏览器。 Thaat 还允许我们截取失败测试的屏幕截图，以帮助调试失败。

如果我仍然在那里工作，我也会尝试使用 phantomjs，看看它是否有效，然后使用更可靠和/或更快的那个。

env.rb 中没有什么不同，我们在本地运行时使用的文件与在 jenkins 上使用的文件相同。

编辑:2017 年末的更新.. 随着最近的变化，当前推荐的 headless 浏览最佳解决方案是使用 chrome 以及 chromedriver 和 chrome 的新 headless 选项。
