从Ant进程调用时,Selenium Edge驱动程序不会初始化 - java

标签: java selenium selenium-webdriver microsoft-edge

我试图在边缘运行一些硒测试,我遇到了这个问题:

当我从java环境(例如JDeveloper)运行它们时,一切正常。但是,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未初始化并抛出和未知异常错误。

我很确定错误不在ant文件中,因为如果我在chrome中运行相同的测试,它可以正常工作。

这是代码失败的部分:

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

我确信这个问题不在路径中,因为当我直接从课程中运行它时,它就可以工作了。此外,我已检查了内部版本号,并且我有正确的MicrosoftWebDriver.exe,因此也不是问题。

我得到的错误如下:

org.openqa.selenium.WebDriverException: Unknown error
[java] Command duration or timeout: 1.20 seconds

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

更新: 我能够恢复完整的日志,这是以后的事情:

错误确实给了我们一些提示:

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'
System info: host: 'FORMIGA', ip: '172.25.208.1', os.name: 'Windows 8', os.arch: 'amd64', os.version: '6.2', java.version: '1.7.0_25'
Driver info: org.openqa.selenium.edge.EdgeDriver

这实质上意味着EdgeDriver二进制文件根本没有检测到并且未初始化会引发未知错误

您的主要问题是您使用的二进制文件中的版本兼容性,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 (已发布 2015-10-09 19:55:52 )[as per the error stack trace within your question]
  • 您正在使用 EdgeDriver (版本 UNKNOWN 给我们)
  • 您正在使用 Edge Browser (版本 UNKNOWN 给我们)

分析

很明显:

  • 您的 JDK Version 已过期。
  • EdgeDriver 二进制文件没有检测到。

解决方案

  • JDK 更新为最近的JDK 8u151级别。
  • Selenium升级到当前级别Version 3.8.1
  • EdgeDriver升级到当前v5.16299级别。
  • Edge Browser升级到支持的v16.16299级别。
  • 通过Clean
  • Re-BuildIDE您的项目
  • 清除Browser Cache
  • 运行CCleaner工具以清除所有操作系统杂务。
  • 如果您的Edge Browser基础版本太旧,请使用Web Browser卸载Moderate ScanRevo Uninstaller并安装最近的 GA已发布版本Web Browser
  • 执行Test
