Question

尝试在Selenium Grid上设置phantomjs节点时遇到错误（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

[edit] 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，这不是该插件提供的默认浏览器选项之一。

以上问题是/usr/bin/phantomjs上的操作系统权限;我需要对其进行chmod a+x。

诙谐地添加此额外问题

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

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

添加答案以防有人错过评论。

请检查phantomjs是否对所有用户都有'x'（执行）访问权限。如果没有，则使用该命令更改访问权限。

chmod +x /usr/bin/phantomjs

新错误“此过程尚未退出，因此无法获得结果”主要是硒/驱动程序版本不匹配。您可以尝试降级硒的版本。

顺便说一句，您使用的是什么版本的幻影。

Answer 2

尝试将<div>This one stretches out:</div> <div class="incorrect"> <img src="http://placehold.it/150x50" /> </div> <div>This will preserve aspect ratio and look right:</div> <div class="correct"> <img src="http://placehold.it/150x50" /> </div>添加到Jenkins的Java标记中（通常查看-Dphantomjs.binary.path=/usr/bin/phantomjs或/etc/default/jenkins）。

Answer 3

juste在命令行中添加路径，如下所示：

'/usr/bin/java' -Dphantomjs.binary.path='/home/john/.local/share/binman_phantomjs/linux64/2.1.1/phantomjs-2.1.1-linux-x86_64/bin/phantomjs' -jar '/home/john/.local/share/binman_seleniumserver/generic/3.0.1/selenium-server-standalone-3.0.1.jar'

如何将PhantomJS路径传递给Selenium Grid
