selenium - 当我们使用 Jenkins windows 服务模式执行 selenium 脚本时，从渲染器 : 600. 000 接收消息超时

Question

我们每天都在使用 jenkins 窗口服务( headless 模式)执行我们的 selenium 自动化脚本。它一直工作到昨天。突然它停止工作并且没有启动浏览器。它显示了以下错误消息 [15536​​77874.187][SEVERE]:从渲染器接收消息超时:600.000。之后所有剩余的测试用例都失败了。

如果我们在没有 Windows 服务的情况下使用 jenkins 运行构建，它工作正常。我们仅在使用 Windows 即服务时遇到此问题

我的 chrome 驱动版本:73.0.3683.68

Chrome 浏览器版本:73.0.3683.68

Selenium 版本:3.14.0

我试图降级浏览器版本和驱动程序版本。即使它不起作用

当我们使用 jenkins 作为 Windows 服务执行但收到错误消息时，我希望浏览器应该在后台启动。

System.setProperty("webdriver.chrome.driver", "C:\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("load-extension=C:\\1.13.4_0");
options.addArguments("--start-maximized");
options.addArguments("--ignore-certificate-errors");
options.addArguments("--disable-popup-blocking");
// options.addArguments("window-size=1400,600");
options.addArguments("enable-automation");
options.addArguments("--headless");
options.addArguments("--window-size=1920,1080");
options.addArguments("--no-sandbox");
// options.addArguments("--disable-extensions");
options.addArguments("--dns-prefetch-disable");
options.addArguments("--disable-gpu");
options.setPageLoadStrategy(PageLoadStrategy.NORMAL);
DesiredCapabilities capabilities = 
DesiredCapabilities.chrome();
capabilities.setCapability(ChromeOptions.CAPABILITY, 
**strong text**options);
return new ChromeDriver(capabilities);

似乎您正在使用以下配置:

chromedriver=73.0.3683.68

Chrome =73.0.3683.68

Windows 操作系统

John Chen(所有者 - chromedriver)最近证实，

We have confirmed issues with take screenshot when Chrome 73.0.3686.75 is started by a service (such as Jenkins or Task scheduler) on Windows. Please see https://crbug.com/942023 for more details. We apologize for any inconvenience caused by this. However, we haven't yet been able to observe similar issue on Linux, so we appreciate any help you can provide to enable us to reproduce the issue on Linux. We don't have access to TeamCity, but we have tested take screenshot using Docker image produced by Selenium (selenium/standalone-chrome:3.141.59-lithium), and didn't find any problems.

昨天(2019年3月26日)，约翰再次确认:

I am aware of some issues with running Chrome 73 from Jenkins. I don't know any workarounds. Please following https://crbug.com/942023 for updates.

更新

我们能够挖掘出主要问题。主要问题不在于 ChromeDriver v73.x 本身，而在于 Chrome v73.x 约翰正式确认为:

The root cause is indeed in Chrome 73.x, not in ChromeDriver. We are working with Chrome devs to find a solution.

解决方案

快速修复解决方案是:

将 Chrome 浏览器降级到 Chrome v72.x

在以下各项中使用匹配的 ChromeDriver:

ChromeDriver 2.46

ChromeDriver 72.0.3626.69

Note: If you are using Chrome version 72, please download ChromeDriver 2.46 or ChromeDriver 72.0.3626.69

确保 JDK 升级到最新级别 JDK 8u202 .

更新(2019 年 4 月 3 日)

添加参数 --disable-features=VizDisplayCompositor通过 ChromeOptions() 的实例似乎解决了这个问题:

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