使用此页面作为参考：http : //executeautomation.com/blog/running-chrome-in-headless-mode-with-selenium-c/

我试图让Chrome在无头模式下工作（以在SpecFlow / xUnit下运行）。这失败了，我想知道是否有人有解决方案/解决方案。

我正在Windows 7上使用.NET 4.7控制台应用程序和Google Chrome版本65.0.3325.162（官方构建）（64位）运行VS 2015。

这是我的packages.config：

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="Selenium.Support" version="3.11.0" targetFramework="net461" />
  <package id="Selenium.WebDriver" version="3.11.0" targetFramework="net461" />
  <package id="Selenium.WebDriver.ChromeDriver" version="2.36.0" targetFramework="net461" />
  <package id="xunit" version="2.3.1" targetFramework="net461" />
  <package id="xunit.abstractions" version="2.0.1" targetFramework="net461" />
  <package id="xunit.analyzers" version="0.8.0" targetFramework="net461" />
  <package id="xunit.assert" version="2.3.1" targetFramework="net461" />
  <package id="xunit.core" version="2.3.1" targetFramework="net461" />
  <package id="xunit.extensibility.core" version="2.3.1" targetFramework="net461" />
  <package id="xunit.extensibility.execution" version="2.3.1" targetFramework="net461" />
  <package id="xunit.runner.visualstudio" version="2.3.1" targetFramework="net461" developmentDependency="true" />
</packages>

这是我的Class1.cs：

using OpenQA.Selenium.Chrome;
using Xunit;

namespace xUnitSpecFlowChrome
{
    public class Class1
    {
        [Fact]
        public void GoTest()
        {
            var options = new ChromeOptions();
            options.AddArgument("--headless");
            options.AddArgument("start-maximized");
            options.AddArgument("--disable-gpu");
            options.AddArgument("--disable-extensions");
            var driver = new ChromeDriver(options);

            driver.Navigate().GoToUrl("http://www.daringfireball.net");
            var title = driver.Title;
        }
    }
}

这是我在运行该测试时在输出中看到的内容：

真不敢相信是这样的：
