超时异常：等待 selenium webdriver 的 net.serenitybdd.core.pages.WebElementFacade 40 秒后超时

Question

我正在运行 selenium 测试并突然低于错误。测试运行并非每次都始终如一地通过。有时会失败，有时会通过。而且失败的步骤也不是固定的，每次都在不同的步骤失败。

错误信息： 超时异常：等待 net.serenitybdd.core.pages.WebElementFacade for selenium webdriver 40 秒后超时

以下是我正在使用的版本： 铬 - v65 Chrome 驱动程序 - v2.38 硒 - v2.53 宁静 - v1.1.36

我没有编写代码，因为它没有固定在哪一步会失败。 有人可以帮忙吗？

添加错误跟踪：

此错误消息...

...暗示服务员引发了 TimeoutException 并且无法找到元素。

但是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：

• 您的 Selenium 客户端 版本是 2016-03-15 10:43:46 的 2.53.0，高于 2 岁。
• 您的 JDK 版本是 1.8.0-ea，相当古老。

所以 JDK v8u0-ea、Selenium Client v2.53.0、Chrome v65.x 和 之间存在明显的不匹配>ChromeDriver v2.38

解决方案

• 将 JDK 升级到最新级别 JDK 8u162。
• 将Selenium升级到当前级别Version 3.11.0。
• 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 工具在执行测试套件之前和之后清除所有操作系统杂务。
• 如果您的基础 Web Client 版本太旧，请通过Revo Uninstaller 卸载它并安装最新的 GA 和发布版本的 Web Client。
• 进行系统重启。
• 执行您的@Test。
