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

本文介绍了错误 [严重]:从渲染器接收消息超时:20.000 在 Jenkins 上通过 Selenium 执行测试套件时的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

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.
