【发布时间】：2020-05-13 18:14:45
【问题描述】：

我正在尝试使用以下代码在 firefox 上运行测试，但在 Windows Server 2012 R2 上运行测试时遇到异常。但相同的代码适用于 MAC 和 windows 10

Firefox 版本 - 72.0.2

Gecko 驱动程序版本 - 0.26

用于集线器和节点的 Selenium 独立服务器 - 3.141.59

所需功能的代码：

dc = DesiredCapabilities.firefox();
dc.setCapability("marionette", true);
dc.setCapability("webdriver.gecko.driver","C:\\AutomationPrograms\\geckodriver.exe");
dc.setBrowserName(browser);
dc.setJavascriptEnabled(true);
dc.setPlatform(Platform.ANY);

错误：

【解决方案1】：

此错误消息...

Build info: version: '3.141.59', revision: 'e82be7d358', time: '2018-11-14T08:25:53'
System info: host: 'M-AMS-DEVELOPER', ip: '108.61.189.113', os.name: 'Windows Server 2012 R2', os.arch: 'amd64', os.version: '6.3', java.version: '1.8.0_152'
Driver info: driver.version: unknown

...暗示 GeckoDriver 无法启动/生成新的浏览上下文，即 Firefox 浏览器 会话。

您的主要问题是您使用的二进制文件版本之间的不兼容性，如下所示：

您的 GeckoDriver、Firefox 和 Selenium Client 版本是最新版本。
但是您的 JDK 版本 是 1.8.0_152，相当旧。

解决方案

将 JDK 升级到最新级别 JDK 8u222。
进行系统重启。
以非 root 用户身份执行 Test。

【讨论】：

ty 用于解决方案@DebanjanB。会试试这个并回复你
@Rameshwar JDK 8 的最新版本，更好。
我试过 jdk 8u241，它比 8u222 更好。但仍然遇到同样的错误
@Rameshwar 不，你没有得到同样的错误。在这个问题中，您的错误是 Driver info: driver.version: unknown at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)，但您的 new question 中的错误是 org.openqa.selenium.WebDriverException: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:46285 at org.openqa.selenium .remote.service.DriverCommandExecutor.execute(DriverCommandExecutor.java:92)
没错。这就是为什么我创建了一个不同的问题。

【解决方案2】：

我尝试运行 geckdirver.exe 文件并得到 vcruntime140.dll was not found 的错误。所以我不得不从这个link下载Microsoft Visual C++ 2015 Redistributable Update 3 RC。

geckodriver.exe 的位置也有问题。

我已将它放在 Jenkins 工作区中，但它没有执行。我将它移到 Jenkins 工作区以外的文件夹中，它运行良好
