如何将PhantomJS路径传递给Selenium Grid

Question

尝试在Selenium Grid上设置phantomjs节点时出现错误(https://wiki.jenkins-ci.org/display/JENKINS/Selenium+Plugin)

我已经设置了以下自定义json配置:

{
  "capabilities": [
    {
      "browserName": "phantomjs",
      "phantomjs.binary.path": "/usr/bin/phantomjs",
      "platform": "LINUX",
      "maxInstances": 5
    }
  ],
  "configuration": {
    "nodeTimeout":120,
    "port":5555,
    "hubPort":4444,
    "hubHost":"localhost",
    "nodePolling":2000,
    "registerCycle":10000,
    "register":true,
    "cleanUpCycle":2000,
    "timeout":30000,
    "maxSession":1
  }
}

但是当我对它运行webdriver时出现错误:

WebDriverException: Message: The path to the driver executable must be set by the phantomjs.binary.path capability/system property/PATH variable; for more information, see https://github.com/ariya/phantomjs/wiki. The latest version can be downloaded from http://phantomjs.org/download.html

如果我停止插件启动的节点(并保持插件集线器运行),并按如下方式手动运行我自己的节点,它可以正常工作:

java -jar selenium-server-standalone-2.53.0.jar -role webdriver 
    -browser browserName=phantomjs,platform=LINUX 
    -hub http://localhost:4444/grid/register

[编辑] phantomjs可以从shell执行并且位于/ usr/bin/phantomjs:

$ whereis phantomjs
phantomjs: /usr/bin/phantomjs

我无法在线找到phantomjs设置的规范描述,这不是插件提供的默认浏览器选项之一.

以上问题是操作系统权限/usr/bin/phantomjs; 我需要做的chmod a+x.

厚颜无耻地添加这个额外的问题

这有效(由我手动启动):

/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.111.x86_64/jre/bin/java -jar /var/lib/jenkins/selenium-server-standalone-2.53.0.jar -role webdriver -browser browserName=phantomjs,platform=LINUX -hub http://localhost:4444/grid/register

这不是(由selenium插件启动的过程):

/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.111.x86_64/jre/bin/java -cp /var/cache/jenkins/war/WEB-INF/lib/remoting-2.56.jar hudson.remoting.Launcher -cp /var/lib/jenkins/selenium-server-standalone-2.53.0.jar:/var/lib/jenkins/htmlunit-driver-standalone-2.20.jar -connectTo localhost:36322

我在运行测试时遇到的错误: PHPUnit_Extensions_Selenium2TestCase_WebDriverException: The process has not exited yet therefore no result is available

Answer 1

尝试添加-Dphantomjs.binary.path=/usr/bin/phantomjs到 Jenkins 的 Java 标志（通常查看/etc/default/jenkins或/etc/sysconfig/jenkins）。
