我在 C# 中使用 NUnit 和 Selenium 来构建一个框架,该框架包含在多个浏览器上运行多个测试用例。在这种情况下也支持 Microsoft Edge。当我设置测试时,chrome 和 firefox 运行正常,但 edge 出现以下错误:

OpenQA.Selenium.WebDriverException :抛出了一个带有空响应的异常,向远程 WebDriver 服务器发送 HTTP 请求以获取 URL http://localhost:55992/session. 异常状态为 ReceiveFailure,消息为:底层连接已关闭:接收时发生意外错误。----> System.Net.WebException:底层连接已关闭:接收时发生意外错误。----> System.IO.IOException : Unable to read data from the transport connection: 一个现有的连接被远程主机强行关闭。----> System.Net.Sockets.SocketException : 现有连接被远程主机强行关闭 [2018. 06. 17. 17:08:22 警告] 在 OpenQA.Selenium.Remote.HttpCommandExecutor.MakeHttpRequest(HttpRequestInfo requestInfo) 在 OpenQA.Selenium.Remote.HttpCommandExecutor.Execute(Command commandToExecute) 在 OpenQA.Selenium.Remote.DriverServiceCommandExecutor.Execute( OpenQA 中的命令 commandToExecute)。

我试图查找这个特定的错误,我得到的最接近的是远程驱动程序尝试发送一个 HTTP 请求,在这种情况下失败了。由于 Chrome 和 FF 运行正常,我不知道 Edge 出了什么问题。

WebDriverFactory:

using NUnit.Framework;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Firefox;
using OpenQA.Selenium.IE;
using WebDriverManager;
using WebDriverManager.DriverConfigs.Impl;

using OpenQA.Selenium.Edge;
using System;

namespace SeleniumNUnit.Tests

    /// <summary>

    /// </summary>
    public class WebDriverFactory
    {
        public static string path = "C:\\Drivers\\";
        public IWebDriver Driver;

    protected WebDriverFactory(BrowserType type)
    {
        Driver = WebDriver(type);
    }

    [OneTimeTearDown]
    public void TestFixtureTearnDown()
    {
        Driver.Quit();
    }

    /// <summary>

    }

    public static IWebDriver WebDriver(BrowserType type)
    {
        IWebDriver driver = null;

        switch (type)
        {
            case BrowserType.IE:
                driver = EdgeDriver();
                break;
            case BrowserType.Firefox:
                driver = FirefoxDriver();
                break;
            case BrowserType.Chrome:
                driver = ChromeDriver();
                break;
        }

        return driver;
    }

    /// <summary>

        FirefoxOptions options = new FirefoxOptions();
        IWebDriver driver = new FirefoxDriver(options);
        return driver;

测试代码:

using System;
using NUnit.Framework;
namespace SeleniumNUnit
{
    [TestFixture(SeleniumNUnit.Tests.WebDriverFactory.BrowserType.Chrome)]
    [TestFixture(SeleniumNUnit.Tests.WebDriverFactory.BrowserType.Firefox)]

    }

    [OneTimeSetUp]
    public void SetUpEnvironment()
    {
        Driver.Navigate().GoToUrl("http://google.com");

    }

    [Test]
    public void validateTitle()
    {
        Assert.That(Driver.Title.Contains("Google"));
    }

    [OneTimeTearDown]

        Driver.Quit();
        Driver.Dispose();

我遇到了同样的问题,但后来我发现了这个:

Selenium.WebDriver.MicrosoftDriver v17.17134.0 运行测试时崩溃

长话短说,检查您的 Windows 版本。如果是17134版本,那么获取MicrosoftWebDriver 17134版本。但是,如果您使用的是 16299.xxx,则必须使用 16299 版本的 MicrosoftWebDriver。
