“收到未知命令"； MicrosoftWebDriver和Selenium(C#)时出错 [英] "Unknown command received" errors using MicrosoftWebDriver and Selenium (C#)
问题描述
我正在使用Selenium(v2.47)和Microsoft Web驱动程序(v10.0.10240.0).我正在使用一些已经可以在Firefox，IE和Chrome上正常运行的C#代码，并且我想使用它在Windows 10上测试新的Edge浏览器.我的代码能够成功打开浏览器并导航到我的登录页面.但是，当我执行一些基本操作时，会出现收到未知命令"异常:
I am using Selenium (v2.47) and the Microsoft Web Driver (v10.0.10240.0). I am working with some existing C# code that already runs fine on Firefox, IE and Chrome and I want to use it to test the new Edge browser on Windows 10. My code is able to successfully open the browser and navigate to my login page. However I get an "Unknown command received" exception when I do a few basic things such as:
1)最大化浏览器
2)在现有IWebElement上调用.FindElement(by).
2) call .FindElement(by) on an existing IWebElement.
例如:
driver.Manage().Window.Maximize(); //引发异常
driver.Manage().Window.Maximize(); //throws exception
...
IWebElement parent = driver.FindElement(By.TagName("body")); //有效
IWebElement parent = driver.FindElement(By.TagName("body")); //works
...
parent.FindElement(by); //引发异常
parent.FindElement(by); //throws exception
有没有人看到Edge浏览器将Selenium和C#与这两种方法一起使用?也许我在这里做错了.还是收到未知命令"只是意味着将来会出现未实现的功能?
Has anyone seen either of these work with Selenium and C# for the Edge browser? Maybe I am doing something wrong here. Or does "Unknown command received" just mean it is unimplemented functionality that will come in the future?
推荐答案
在最初的Edge驱动程序(10.0.10240)版本中有相当多的功能缺失，包括缺少对IWebElement.FindElement()的支持.后续发行版也需要通过Windows 10更新对Edge本身进行更新，直到最近才可以通过所谓的Insider构建来获得. Microsoft在其
There was a fair amount of missing functionality in the initial (10.0.10240) Edge driver release, including missing support for IWebElement.FindElement(). Subsequent releases, which also required an update to Edge itself via Windows 10 updates, and until very recently only available via so-called Insider builds. A full accounting of what was implemented and when is provided by Microsoft at their WebDriver implementation status page.
