Question

我试图让selenium网格第一次工作。

在设置中我有以下

            Driver = new ChromeDriver(AppDomain.CurrentDomain.BaseDirectory + "../../../Drivers");

            DesiredCapabilities capabilities = new DesiredCapabilities();
            capabilities = DesiredCapabilities.Chrome();
            capabilities.SetCapability(CapabilityType.BrowserName, "chrome");
            capabilities.SetCapability(CapabilityType.Platform, new Platform(PlatformType.Windows));

            Driver = new RemoteWebDriver(new Uri("http://localhost:4444/wd/hub"), capabilities);

这是在c＃中使用XUNIT并使用resharper执行。

我在visual studio中收到错误

OpenQA.Selenium.WebDriverException
Unexpected error.

errorResponse)

在控制台中，我收到以下错误

2017-11-06 17:08:35.821:WARN:osjs.HttpChannel:qtp22982090-131: 
/wd/hub/session

    at org.openqa.grid.web.servlet.DriverServlet.process(DriverServlet.java:135)

和

Caused by: org.openqa.grid.common.exception.GridException: Cannot extract a capabilities from the request: {"desiredCapabilities":{"browserName":"chrome","version":"","platform":"WINDOWS","javascriptEnabled":true},"capabilities":{"firstMatch":[{"browserName":"chrome","javascriptEnabled":true}]}}

和

Caused by:java.lang.IllegalArgumentException: Illegal key values seen in w3c capabilities: [javascriptEnabled]

这是我第一次尝试使用硒网格，任何指南或提示都将非常受欢迎。

我发现了这个

https://github.com/SeleniumHQ/selenium/issues/4461

将selenium更新为3.7.0后，我不再收到此错误。

显然，Selenium Grid 2和Selenium 3.4 / 5存在问题，因此更新NuGet包的最新版本将解决此问题。
