Selenium无法从Jenkins运行Firefox浏览器 [英] Selenium Not able to run Firefox browser from Jenkins

问题描述

我尝试通过Ubuntu计算机上的jenkins在Firefox上使用硒运行自动测试，但无法运行它.但是，使用Eclipse可以运行相同的代码而不会失败.我正在将其作为Maven项目运行.

I tried running Automated test using selenium on firefox through jenkins on Ubuntu Machine but not able to run it. But the same code is running without failure using Eclipse. I am running it as maven project.

遇到以下错误-

推荐答案

此错误消息...

...表示牵线木偶无法启动与 WebClient 即 Firefox 浏览器的活动连接.

...implies that the marionette wasn't able to initiate an active connection with the WebClient i.e Firefox browser.

您的主要问题是所使用的二进制文件之间的版本兼容性:

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

• 您的 Selenium Client 版本是 3.11.0 .
• 您的 JDK版本是 1.8.0_131 ，这很古老.
• 您的 GeckoDriver 版本是 v0.20.0 .
• 您不知道您的 Firefox 版本.

• Your Selenium Client version is 3.11.0.
• Your JDK version is 1.8.0_131 which is pretty ancient.
• Your GeckoDriver version is v0.20.0.
• Your Firefox version is unknown to us.

因此 JDK v8u131 ， Selenium Client v3.11.0 和 GeckoDriver v0.20.0 之间存在明显的不匹配.

So there is a clear mismatch between the JDK v8u131 , Selenium Client v3.11.0 and GeckoDriver v0.20.0.

• 将 JDK 升级到最新级别 JDK 8u162 .
• 将 GeckoDriver 升级到 GeckoDriver v0.20.1 级.
• 确保根据您的代码块，在指定位置存在 GeckoDriver .
• 确保 GeckoDriver 对非root用户用户具有可执行权限.
• 将 Firefox 版本升级到 Firefox v59.0.2 级别.
通过 IDE
• 清理您的项目工作区和重建您的项目，并且仅具有必需的依赖项.
• 使用 CCleaner 工具清除之前和之后的所有操作系统杂项在执行 Test Suite 之后.
• 如果您的基本 Web客户端版本太旧，请通过来卸载. Revo Uninstaller 并安装最新版本的 Web客户端 GA和发行版.
• 进行系统重启.
• 以非root用户身份执行Test.
• 始终在tearDown(){}方法中调用driver.quit()以关闭&优雅地销毁 WebDriver 和 Web Client 实例.

• Upgrade JDK to recent levels JDK 8u162.
• Upgrade GeckoDriver to GeckoDriver v0.20.1 level.
• Ensure that GeckoDriver is present in the specified location as per your code block.
• Ensure that GeckoDriver is having executable permission for non-root users.
• Upgrade Firefox version to Firefox v59.0.2 levels.
• 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 as a non-root user.
• Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
