selenium - Windows 10 上使用 IEDriverServer 和 IE 11 时出现 java.net.ConnectException : Failed to connect to localhost error with Selenium 3. 11.0

Question

我对 Selenium 非常陌生，并尝试在我的笔记本电脑中设置 Selenium 。我无法从我的简单代码中调用 IE。详细内容如下。您能帮我了解问题出在哪里

IE版本:IE 11，IE驱动程序:64位，操作系统:Windows 10 64 位， Selenium 版本:3.11

错误:

错误说明了一切:

3.9.0.0
Exception in thread "main" org.openqa.selenium.WebDriverException: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:29313
Build info: version: '3.11.0', revision: 'e59cfb3', time: '2018-03-11T20:33:08.638Z'
System info: host: 'DESKTOP-B1D1PSJ', ip: '192.168.79.96', os.name: 'Windows 10', os.arch: 'amd64', os.version: '10.0', java.version: '1.8.0_161'
Driver info: driver.version: InternetExplorerDriver

从错误堆栈跟踪中可以清楚地看出，新的 session 没有启动，driver.version也没有被识别。

您的主要问题是您正在使用的二进制文件之间的版本兼容性，如下所示:

• 您正在使用Selenium Client v3.11.0
• 您正在使用IEDriverServer v3.9.0.0
• 您正在使用 InternetExplorer v11.0(根据您的问题)

因此，Selenium Client v3.11.0 和 IEDriverServer v3.9.0.0 之间存在明显的不匹配。

解决方案

• 将 IEDriverServer 升级到 v3.11.1 .
• 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。
• 使用CCleaner工具可以清除执行测试套件之前和之后的所有操作系统杂务。
• 如果您的基本网络浏览器基本版本太旧，请通过 Revo Uninstaller 卸载它并安装最新的 GA 和发布版本的网络浏览器。
• 执行您的@Test。

其他注意事项

• 您使用的标志 INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS, true 违反了 best practice 。不要这样做。
