黄瓜无头 xvfb ubuntu [英] Cucumber headless xvfb ubuntu

问题描述

我正在尝试在 Amazon EC2 上设置 Jenkins 构建服务器.我计划在无头模式下运行我的黄瓜测试套件.我成功地在 IRB 中无头运行

I'm trying to setup a Jenkins build server on Amazon EC2. I'm planning on running my cucumber test suite in headless mode. I was successfully able to run headless in IRB

require 'watir-webdriver'
require 'headless'
headless = Headless.new
headless.start
b = Watir::Browser.new(:chrome)
b.goto("www.google.com")
b.title
b.close
headless.destroy

但如果我将以下内容添加到我的 env.rb

but if I add the following to my env.rb

if ENV['HEADLESS']
  require 'headless'
  headless = Headless.new
  headless.start
  at_exit do
    headless.destroy
  end
end

然后运行

cucumber ENV=HEADLESS features/test.feature:25

我收到以下错误.

任何帮助将不胜感激.谢谢！！

Any help will be appreciated. Thanks!!

推荐答案

问题出在命令行 env 参数中

The problem was in the command line env parameter

cucumber HEADLESS=true features/test.feature:25 

而不是

cucumber ENV=HEADLESS features/test.feature:25
