如何将PhantomJS路径传递到Selenium Grid [英] How to pass PhantomJS path to Selenium Grid

问题描述

尝试在Selenium Grid上设置phantomjs节点时出现错误(

I'm getting an error when trying to set up a phantomjs node on Selenium Grid (https://wiki.jenkins-ci.org/display/JENKINS/Selenium+Plugin)

我已经设置了以下自定义json配置:

I've set up the following custom json configuration:

{
  "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:

But I get an error when I run webdriver against it:

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

如果我停止由插件启动的节点(并保持插件集线器运行)，并按如下所示手动运行我自己的节点，则效果很好:

If I stop the node started by the plugin (and keep the plugin hub running), and manually run my own node as follows, it works fine:

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

[edit] phantomjs可从Shell执行，并位于/usr/bin/phantomjs:

[edit] phantomjs is executable from the shell and lives at /usr/bin/phantomjs:

$ whereis phantomjs
phantomjs: /usr/bin/phantomjs

我在网上找不到phantomjs设置的规范描述，这不是该插件提供的默认浏览器选项之一.

I can't find a canonical description online of a phantomjs setup and this isn't one of the default browser options provided by the plugin.

上述问题是/usr/bin/phantomjs上的操作系统权限；我需要对它进行chmod a+x.

The problem with the above was the OS permissions on /usr/bin/phantomjs; I needed to do chmod a+x on it.

乐意添加此附加问题

此方法有效(由我手动启动):

This works (manually started by me):

/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(该过程由selenium插件启动):

This doesn't (the process started by the selenium plugin):

/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

运行测试时出现错误: PHPUnit_Extensions_Selenium2TestCase_WebDriverException: The process has not exited yet therefore no result is available

Error I'm getting when running the test: PHPUnit_Extensions_Selenium2TestCase_WebDriverException: The process has not exited yet therefore no result is available

推荐答案

添加答案，以防万一有人错过评论.

Adding the answer just in case someone misses the comment.

请检查phantomjs是否对所有用户都具有"x"(执行)访问权限.如果不是，则使用命令更改访问权限.

Please check if phantomjs has 'x' (execute) access for all users. If it doesnt, then use the command to change the access.

chmod +x /usr/bin/phantomjs

新错误该过程尚未退出，因此没有结果可用"主要是硒/驱动程序版本不匹配.您可以尝试降级硒的版本.

The new error "The process has not exited yet therefore no result is available" mostly comes with selenium/driver version mismatch. You could try downgrading the version of selenium.

顺便说一句，您正在使用什么版本的phantomjs.

Btw, what version of phantomjs are you using.
