Ruby Selenium Webdriver Chromedriver在无头模式下启动时超时

我使用的是SeleniumWebDriver，带有Ruby 32位1.9.3、Chromedriver v2.9.248315、Chrome38.0.2125.111M和Jenkins 1.588的本地实例

Gems:cucumber（1.3.17）、selenium webdriver（2.43.0）、watir webdriver（0.6.11）（如果您认为有必要，可以提供所有其他webdriver的列表）

Windows7专业版64位版本

当运行一个Jenkins作业，使用chromedriver启动Chrome，然后尝试与之交互时，我得到一个超时错误。当在我的桌面上通过命令提示符窗口执行同样的操作时，它可以完美地工作。运行相同的Jenkins任务，启动Firefox而不是Chrome，它工作得非常好

简单示例（C:\test.rb）：

Jenkins作业配置为运行Windows批处理命令：

cd \
ruby test.rb

运行作业时的输出：

生成步骤“执行Windows批处理命令”将生成标记为失败

我曾尝试在Jenkins服务中启用“允许服务与桌面交互”，然后观察窗口（在更复杂的场景中），Chrome窗口打开，但什么也没做。我最初对“$browser.cookies.clear”有问题，在注释掉这一行之后，我现在对$browser.driver.manage.window.maximize行也有同样的问题

我正在运行复杂的黄瓜场景，使用Chromedriver没有任何问题。然后我重建了我的电脑，在安装了Jenkins、Ruby和Chromedriver（将两者都添加到PATH中）并将旧作业复制到我的新Jenkins安装后，我遇到了上述问题。然后我创建了上面的简单示例，对其进行了测试，并创建了这篇文章

如果有人对如何让Chromedriver重新工作有任何想法，那就太好了。

Chrome无法在windows中以无头模式运行。 您需要使用HTMLdriver来完成此操作

如果您非常需要它，您需要尝试设置一个vnc服务器并在其中运行。

---

在会话0中以系统用户身份运行时，Chrome 38不工作。通常情况下，这是因为Chrome是由Windows服务启动的——在您的例子中，Jenkins是作为服务运行的。这是一个众所周知的问题。请参阅硒问题和

两种解决方案：

将Chrome降级到低于38的版本

下载并安装

---

AlwaysUp解决方案确实有效，但许可成本很低，或者如果你不担心Chrome版本，你可以将其降级。

SDET的回答帮助了我（投票结果为上），会话0是我的问题，但你不需要AlwaysUp，您可以通过：

javaws从一些启动脚本启动jenkins slavehttp:///computer//slave-agent.jnlp

我不知道“headless mode”（无头模式）是否是我要做的事情的正确词汇，但它确实有效，它在重建之前在我的机器上有效，在另一台服务器和另一个人的机器上有效。Jenkins在“虚拟桌面”上启动了一个Chrome实例，然后应该运行测试，但它不在我的机器上。我刚刚尝试了3个。更改了Jenkins的服务条目中的用户，我在脚本中添加了一个whoami，以确认它现在使用的是不同的用户（它是）。我仍然得到完全相同的错误。我有Chrome 38，所以我会尝试降级Chrome版本更新的答案，以删除不起作用的选项。我似乎找不到降级Chrome的方法，我能找到的所有合法下载都将我重定向到Google Chrome下载页面，这迫使我下载最新版本的Chrome。不过，看起来他们会在Chrome39中修复它
