从ant process java调用时，Selenium边缘驱动程序未初始化

4 月，2 周 Questions & Answers 645

我试图在edge中运行一些selenium测试，但遇到了以下问题：

当我从java环境（例如JDeveloper）运行它们时，一切都正常。然而，我们已经设置了一个ant进程来从命令行调用测试。当我尝试这样做时，WebDriver未初始化并抛出未知异常错误

我非常确定错误不在ant文件中，因为如果我在chrome中运行相同的测试，它就可以正常工作

这是代码中失败的部分：

System.setProperty("webdriver.edge.driver","PathToFolder\\MicrosoftWebDriver.exe"); 
DesiredCapabilities capability = DesiredCapabilities.edge();
driver = new EdgeDriver(capability);

我确信问题不在路径中，因为当我直接从类运行它时，它工作正常。此外，我已经检查了版本号，并且有了正确的MicrosoftWebDriver。exe，所以这也不是问题所在

我得到的错误如下：

org.openqa.selenium.WebDriverException: Unknown error
[java] Command duration or timeout: 1.20 seconds
[java] Build info: version: '2.48.2', revision: '41bccdd', time: '2015-10-09 19:55:52'

[java] Driver info: org.openqa.selenium.edge.EdgeDriver

更新：我能够恢复完整日志，这是一个错误：

该错误确实给了我们一些提示，如下所示：
```
java.lang.Error: org.openqa.selenium.WebDriverException: Unknown error
Command duration or timeout: 1.01 seconds
Build info: version: '2.48.2', revision: '41bccdd', time: '2015-10-09 19:55:52'

Driver info: org.openqa.selenium.edge.EdgeDriver
```
{cdstrong}这意味着未初始化的二进制错误

您的主要问题是所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JDK Version 1.7.0_25[as per the error stack trace within your question]
- 您正在使用Selenium Version 2.48.2（发布时间2015-10-09 19:55:52）[^{]
- 您正在使用EdgeDriver（我们不知道版本）
分析

很明显：

您的JDK Version已过期
未检测到二进制文件

解决方案

将JDK更新到最近的^{}级别
将Selenium升级到当前级别^{}
将EdgeDriver升级到当前的^{}级别
将Edge Browser升级到支持的^{}级别
Clean和Re-Build通过IDE完成项目
清除Browser Cache

运行^{}工具来清除所有操作系统的杂务
如果您的Edge Browser基本版本太旧，请通过Moderate Scan卸载Web Browser到^{}，并安装Web Browser的最新发布的GA版本
执行Test：
