Question

在Windows 10 VM上启动Microsoft Edge的远程Web驱动程序会话时出现错误。我们有一个配置有多个节点的selenium网格，这些节点具有各种OS /浏览器组合。除了我们的新Windows 10节点之外的所有节点都按预期工作。我们已使用Microsoft Edge浏览器version=21.10586.0.0配置了Windows 10 VM，并在VM上添加了MicrosoftWebDriver。 VM上Web驱动程序的路径使用系统属性 -

进行设置

-Dwebdriver.edge.driver="C:\Selenium\MicrosoftWebDriver.exe"

在我的selenium测试中，我实例化了配置为Windows 10 VM上MicrosoftWebDriver的selenium web驱动程序。在初始化期间，我设置了远程驱动程序的功能，并且我有设置的日志输出：

08:57:32.932 INFO - Executing: [new session: Capabilities [{platform=WINDOWS, javascriptEnabled=true, browserName=MicrosoftEdge, applicationName=Win10_EDGE, version=21.10586.0.0}]])
08:57:32.948 INFO - Creating a new session for Capabilities [{platform=WINDOWS, javascriptEnabled=true, browserName=MicrosoftEdge, applicationName=Win10_EDGE, version=21.10586.0.0}]

建立远程连接，在VM上打开Edge浏览器并且可以运行。此时代码挂起在selenium代码中创建远程驱动程序 - selenium-remote-driver-2.53.0.jar

最终它超时错误：

我正在使用：硒的服务器独立-2.53.0.jar， Microsoft WebDriver 2015年秋季从Microsoft站点更新

我注意到上面的系统信息列出了Windows 8 - 即使安装了Windows 10。

有没有其他人看过这个问题或者知道出了什么问题？

Answer 1

在我成功但痛苦地将Edge设置为Selenium网格的一部分的过程中，我得到了非常相似的异常。这里至少有两个可能的问题：

selenium-standalone-server是在后台启动的（例如使用Task-Scheduler）还是前台？（例如手动或作为启动程序）边缘驱动程序必须在前台运行，以便其窗口可以实际显示在桌面上。因此，节点无法在启动时作为Windows服务启动，也不能从Windows任务计划程序启动。自动启动节点的最佳方法是配置自动登录并添加批处理脚本，将节点启动到用户的启动程序，如my article中所述。
是否在与Edge相同的节点中启用了其他浏览器？这已知会引起问题。建议在同一台机器上启动2个独立的节点（当然在不同的端口上）：一个仅用于Edge，第二个用于IE，FF和Chrome。有关详细信息，请参阅this answer。

在Windows 10 VM上使用Microsoft Edge Web浏览器启动新的remoteWebDriver会话时，Selenium挂起
