JMeter - Webdriver 无法在 Chrome 上加载网页

Question

我根据网上的一个简单示例编写了 JMeter - Webdriver 测试。负载测试应加载 Chrome 并打开特定页面。 Chrome打开，但页面未显示，jmeter返回错误。

这些是规格：

os.name: 'Windows Server 2012 R2', os.arch: 'amd64', os.version: '6.3', java.version: '1.8.0_144'
Chrome version: 65 and higher versions
Jmeter: 5.1.1, selenium-chrome-driver-3.14.0.jar,selenium-java-3.14.0.jar

Thread Group
  jp@gc - Chrome Driver Config
        path to Chrome driver : C:\Program Files (x86)\Google\Chrome\Application\chrome.exe
  jp@gc - WebDriver Sampler        
      WDS.sampleResult.sampleStart()
      WDS.browser.get('http://www.jmeter-plugins.org')
      WDS.sampleResult.sampleEnd()

我期望在Chrome中查看页面，只打开了Chrome，但没有加载具体页面。

感谢您花时间帮助我解决问题。

请根据您的浏览器版本从以下链接下载 chrome 驱动程序，如果不可用，请更新 chrome 浏览器：-
