错误[严重]：在Jenkins上通过Selenium执行测试套件时，从渲染器接收消息超时：20.000

Question

我使用ChromeDriver和Selenium来运行自动测试。测试套件在Eclipse和命令行中都成功运行。然而，当我试图在Jenkins中构建它时，它并没有运行。

这是生成的控制台输出：

有人知道原因吗？谢谢。




Answer 1

删除超时为我解决了这个问题：

driver.manage().timeouts().implicitlyWait
driver.manage().timeouts().pageLoadTimeout
driver.manage().timeouts().setScriptTimeout

喜欢

//driver.manage().timeouts().implicitlyWait(2000, TimeUnit.MILLISECONDS);
//driver.manage().timeouts().pageLoadTimeout(40, TimeUnit.SECONDS);
//driver.manage().timeouts().setScriptTimeout(60, TimeUnit.SECONDS);

Answer 2

此错误消息...

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

...意味着ChromeDriver无法启动新的Chrome浏览器进程。

您的主要问题是正在使用的二进制文件之间的版本兼容性，如下所示：

• 您使用的是chromeDrive=2.33
• chromeDriver=2.33的发行说明清楚地提到了以下内容：

支持Chrome v60-62

• 您正在使用chrome=64.0
• ChromeDriver v2的发行说明。第35条明确提到以下内容：

支持Chromev62-64（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相当古老。

因此，JDK v8u151、Selenium Client v3.8.1、ChromeDriver v2.33和ChromeBrowser v64.0之间存在明显的不匹配

• 将JDK升级到最新级别JDK 8u162
• 将Selenium升级到当前版本3.11.0
• 将ChromeDriver升级到当前的ChromeDriver v2。38级
• 将Chrome版本保持在Chrome v66。x级。（根据ChromeDriver v2.38发行说明）
• 通过IDE清理项目工作区，并仅使用所需的依赖项重建项目
• 在执行测试套件之前和之后，使用CCleaner工具清除所有操作系统杂务
• 如果您的基本Web客户端版本太旧，请通过Revo卸载程序卸载它，并安装最新的GA和发布的Web客户端版本
• 重新启动系统
• 执行@测试
