错误 [严重]:从渲染器接收消息超时:20.000 在 Jenkins 上通过 Selenium 执行测试套件时 [英] Error [SEVERE]: Timed out receiving message from renderer: 20.000 while executing the testsuite through Selenium on Jenkins

问题描述

我使用 ChromeDriver 和 Selenium 来运行我的自动化测试.测试套件在 Eclipse 和命令行中都成功运行.但是，当我尝试在 Jenkins 中构建它时它不会运行.

I use ChromeDriver with Selenium to run my automated tests. The test suite runs successfully in both Eclipse and command line. However, it does not run when I try to build it in Jenkins.

这是我在 Jenkins 中的工作配置(所有信息的名称都经过了保密处理):我可以确认它的 Ant 正在运行 JDK8.

This is my job config in Jenkins (all info has names sanitized for confidentiality): I can confirm it's Ant is running JDK8.

这是构建的控制台输出:

This is the console output of the build:

我下面的 build.xml 大部分是自动生成的，除了我添加 JUnit 集成的末尾:

My build.xml below is mostly auto-generated except for the end where I added JUnit integration:

有谁知道可能是什么原因?谢谢.

Does anyone know what the cause might be? Thanks.

推荐答案

这个错误信息...

[30.168][SEVERE]: Timed out receiving message from renderer: 20.000

...暗示 ChromeDriver 无法启动新的 Chrome 浏览器进程.

...implies that the ChromeDriver was unable to initiate a new Chrome browser process.

您的主要问题是您使用的二进制文件之间的版本兼容性，如下所示:

Your main issue is the version compatibility between the binaries you are using as follows :

• 您正在使用 chromedriver=2.33
• chromedriver=2.33 的发行说明明确提及以下内容:

支持 Chrome v60-62

• 您正在使用 chrome=64.0
• ChromeDriver v2.35 明确提及以下内容:

支持 Chrome v62-64(包括您正在使用的浏览器版本)

• 您的 Selenium 客户端 版本是 3.8.1.
• 您的 JDK 版本是 1.8.0_151，相当旧.
• Your Selenium Client version is 3.8.1.
• Your JDK version is 1.8.0_151 which is pretty older.

所以 JDK v8u151 、Selenium Client v3.8.1 、ChromeDriver v2.33 和 Chrome 之间存在明显的不匹配浏览器 v64.0

• 将 JDK 升级到最新级别 JDK 8u162.
• 将 Selenium 升级到当前级别版本 3.11.0.
• 将 ChromeDriver 升级到当前的 ChromeDriverv2.38 级别.
• 将 Chrome 版本保持在 Chrome v66.x 级别.(根据 ChromeDriver v2.38 发行说明)
• 清理你的项目工作区通过你的IDE和重建你的项目只需要依赖.
• 使用 CCleaner 工具清除之前和在您的测试套件执行之后.
• 如果您的基础 Web Client 版本太旧，请通过 卸载它Revo Uninstaller 并安装最新的 GA 和发布版本的 Web Client.
• 进行一次系统重启.
• 执行你的 @Test.
• Upgrade JDK to recent levels JDK 8u162.
• Upgrade Selenium to current levels Version 3.11.0.
• Upgrade ChromeDriver to current ChromeDriver v2.38 level.
• Keep Chrome version at Chrome v66.x levels. (as per ChromeDriver v2.38 release notes)
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• Use CCleaner tool to wipe off all the OS chores before and after the execution of your Test Suite.
• If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
• Take a System Reboot.
• Execute your @Test.
