超时从渲染器接收消息：10.000，同时在Windows上通过Jenkins使用chromedriver和chrome捕获屏幕截图

时间：2019-03-26 18:32:28

标签： windows selenium google-chrome jenkins selenium-chromedriver

操作系统：Windows 10 浏览器：Chrome 浏览器版本：73.0.3683.86版（正式版本）（32位）

我正在运行硒黄瓜BDD项目，在此我要验证一页的标题。我正在使用扩展报告版本4。项目在本地成功运行。但是当我通过Jenkins运行它时，它在捕获屏幕截图并显示以下错误时失败。

如果我从pom.xml中删除surfire插件，则TEST无法通过Jenkins运行。

在詹金斯的“执行Windows批处理”命令选项中，我给出了以下命令

好像您在 Windows操作系统

上使用 chromedriver = 73.0.3683.68 和 chrome = 73.0.3683.86

John Chen（Chromedriver的所有者）最近确认：

  

我们已经确认，当Windows上的某个服务（例如Jenkins或Task Scheduler）启动Chrome 73.0.3686.75时，拍摄屏幕截图存在问题。有关更多详细信息，请参见https://crbug.com/942023。对于由此带来的任何不便，我们深表歉意。

     

但是，我们尚未能够在Linux上观察到类似的问题，因此，我们感谢您提供的任何帮助，以使我们能够在Linux上重现该问题。我们没有使用TeamCity的权限，但是我们已经测试了使用Selenium生成的Docker映像（selenium / standalone-chrome：3.141.59-lithium）拍摄的屏幕截图，并且没有发现任何问题。

chromedriver73

更新

我们能够挖掘出主要问题。主要问题不是 ChromeDriver v73.x 本身，而是 Chrome v73.x ，John正式确认为：

  

根本原因确实是在Chrome 73.x中，而不是在ChromeDriver中。我们正在与Chrome开发人员一起寻找解决方案。

chrome73_issue

解决方案

解决方案是：

  

注意：如果您使用的是Chrome版本72，请下载ChromeDriver 2.46或ChromeDriver 72.0.3626.69

Outro

更新（2019年4月3日）

通过--disable-features=VizDisplayCompositor的实例添加参数ChromeOptions()似乎可以解决此问题：

ChromeOptions options = new ChromeOptions();
options.addArguments("--disable-features=VizDisplayCompositor");
WebDriver driver = new ChromeDriver(options);
driver.get("https://google.com");

从Team City版本无头运行时，我在运行相同版本的Chrome / Chromedriver时遇到相同的问题。 此操作是在2019年3月25日在构建服务器上安装了最新更新之后开始的。

首先截屏的原因是测试也开始失败，原因是我怀疑与无头模式下虚拟渲染有关的缺陷再次仅限于Chrome实例为通过服务（TeamCity）运行。

当我从构建服务器VM上的命令提示符运行构建脚本时，所有测试都运行良好。

我通过降级chrome版本解决了该问题。说起来容易做起来难：

  1. 我找不到用于获取旧版chrome的官方方法，但是我发现此链接托管了一些内容。使用风险自负： https://www.slimjet.com/chrome/google-chrome-old-version.php

  2. 我下载了版本version 71.0.3578.80

  3. 从构建服务器卸载Chrome，运行此安装程序。

  4. 在安装过程中一旦创建了更新目录： C:\Program Files (x86)\Google\Update 重命名文件GoogleUpdate.exe以防止其自身更新

  5. 在任务计划程序中禁用Google Chrome更新任务

更新：这里的答案表明可以通过将一些附加参数传递给chromedriver来解决该问题，但我尚未测试此解决方案：

在Linux / Ubuntu上，以下版本存在相同的问题：

  • Watir版本：6.16.5
  • 浏览器版本：Chrome 75.0.3770.100
  • 浏览器驱动程序版本：75.0.3770.90
  • 操作系统版本：Ubuntu 16.04 LTS

我遇到了同样的问题，并且删除了

 chromeOptions.addArguments("--window-size=1920,1080");

或使用

 chromeOptions.addArguments("--window-size=1920,1080");
 chromeOptions.addArguments("--force-device-scale-factor=1");

对于chromedriver 81，我也遇到了同样的问题，但是我已经更新到83，所以现在可以正常工作了。

请尝试一下……
