java - 未知错误: cannot determine loading status from disconnected: Unable to receive message from renderer error with Selenium Java scripts on jenkins

Question

我正在学习如何使用ma​​ven和在本地和在jenkins服务器上创建和运行java selenium脚本的教程> eclipse 。

我的脚本非常基本，当通过 Maven 和 TestNG 在 Eclipse 中运行时，在本地运行良好。当我在 Jenkins 上运行它们时，构建需要 3 分钟到 15 分钟，然后通常会因超时渲染问题而失败。

我的脚本在本地运行最多只需要大约 2 分钟。

以前有人遇到过这个问题吗？我不确定为什么他们超时。

来自 Jenkins 的错误

...意味着 ChromeDriver 无法启动/生成新的 WebBrowser，即 Chrome 浏览器 session 。

您的主要问题是您使用的二进制文件版本之间不兼容，如下所示:

• 您正在使用chromedriver=78.0.3904.105
• 您正在使用chrome=78.0.3904.108
• 您的Selenium 客户端版本是2015-02-27 09:10:26的2.45.0，这是古老的 几乎年长5岁。
• 您的JDK版本是1.8.0_101，这是相当古老的。

因此，JDK v8u101、Selenium Client v2.45.0、ChromeDriver v78.0 和 之间存在明显不匹配Chrome 浏览器 v78.0

<小时/>

解决方案

确保:

• JDK 已升级到当前级别 JDK 8u222 .
• Selenium 升级至当前级别 Version 3.141.59 .
• 通过IDE清理您的项目工作区，并仅使用所需的依赖项重建项目。
• 如果您的基本网络客户端版本太旧，请通过 Revo Uninstaller 卸载它并安装最新的 GA 和已发布版本的Web 客户端。
• 重新启动系统。
• 以非root用户身份执行@Test。
