BrowserStackLocal - 无法连接到日志文件

Question

我正在尝试运行使用本地浏览器堆栈与本地主机交互来远程自动进行 selenium 测试。我收到以下错误：

Eror while executing BrowserStackLocal start {"state":"disconnected","pid":7512,"message":{"genre":"error","message":"Could not connect to Files!"}}

然后我指定一个日志文件，然后它说：

BrowserStackLocal start {"state":"disconnected","pid":18308,"message":{"genre":"error","message":"Could not connect to -logFile!"}}

它挂在这条线上没有进一步的进展：

browserStackLocal.start(localArgs);

我的代码如下：

var capability = GetBrowserStackCapabilities();
SetBrowserStackLocal(capability);
webDriver = new RemoteWebDriver(new Uri("http://" + ConfigurationManager.AppSettings.Get("BrowserStackServer") + "/wd/hub/"), capability);

private static DesiredCapabilities GetBrowserStackCapabilities()
        {
            var profile = ConfigurationManager.AppSettings.Get("BrowserStackProfile");
            NameValueCollection caps = ConfigurationManager.GetSection(string.Format("capabilities/{0}", profile)) as NameValueCollection;
            var environment = ConfigurationManager.AppSettings.Get("BrowserStackEnvironment");
            NameValueCollection settings = ConfigurationManager.GetSection(string.Format("environments/{0}", environment)) as NameValueCollection;

            DesiredCapabilities capability = new DesiredCapabilities();

            if (caps != null)
            {
                foreach (string key in caps.AllKeys)
                {
                    capability.SetCapability(key, caps[key]);
                }
            }
            if (settings != null)
            {
                foreach (string key in settings.AllKeys)
                {
                    capability.SetCapability(key, settings[key]);
                }
            }

            string username = Environment.GetEnvironmentVariable("BROWSERSTACK_USERNAME") ?? ConfigurationManager.AppSettings.Get("BrowserStackUser");
            string accesskey = Environment.GetEnvironmentVariable("BROWSERSTACK_ACCESS_KEY") ?? ConfigurationManager.AppSettings.Get("BrowserStackKey");
            capability.SetCapability("browserstack.user", username);
            capability.SetCapability("browserstack.key", accesskey);            
            return capability;
        }

        private static void SetBrowserStackLocal(DesiredCapabilities capability)
        {
            if (capability.GetCapability("browserstack.local") != null && capability.GetCapability("browserstack.local").ToString() == "true")
            {
                var browserStackLocal = new Local();
                string accesskey = Environment.GetEnvironmentVariable("BROWSERSTACK_ACCESS_KEY") ?? ConfigurationManager.AppSettings.Get("BrowserStackKey");
                List<KeyValuePair<string, string>> localArgs = new List<KeyValuePair<string, string>> {
                    new KeyValuePair<string, string>("key", accesskey),
                    new KeyValuePair<string, string>("logFile", "C:/Temp/logfile.txt"),
                    new KeyValuePair<string, string>("force", "true")
                };
                browserStackLocal.start(localArgs);
                FeatureContext.Current.SetBrowserStackLocal(browserStackLocal);
            }

        }

我的配置如下：

  <appSettings>
    <add key="BrowserStackUser" value="<redacted>" />
    <add key="BrowserStackKey" value="<redacted>/>
    <add key="BrowserStackServer" value="hub-cloud.browserstack.com" />
    <add key="BrowserStackProfile" value="single" />
    <add key="BrowserStackEnvironment" value="ie11" />
  </appSettings>
  <capabilities>
    <single>
      <add key="browserstack.debug" value="true" />
      <add key="browserstack.local" value="true" />
    </single>
  </capabilities>
  <environments>
    <ie11>
      <add key="os" value="Windows" />
      <add key="os_version" value="8.1" />
      <add key="browser" value="IE" />
      <add key="browser_version" value="11.0" />
      <add key="resolution" value="1024x768" />
    </ie11>
  </environments>

如何避免浏览器堆栈本地挂起并使用本地服务器开始远程测试？

错误“无法连接到 -logFile！”是由于不正确的参数 "logFile"。正确的参数是“logfile”（全部小写）。您应该在此处查看 BrowserStack 的文档 - https://github.com/browserstack/browserstack-local-csharp#logfile。

这是 Browserstack 本地 C# 绑定的工作片段：

using System;
using OpenQA.Selenium;
using OpenQA.Selenium.Remote;
using BrowserStack;
using System.Collections.Generic;
using OpenQA.Selenium.Chrome;

using System.Threading;

namespace BrowserStackLocalSample
{
    class Program
    {
    static void Main(string[] args)
    {
        IWebDriver driver;
        var browserStackLocal = new Local();
        List<KeyValuePair<string, string>> bsLocalArgs = new List<KeyValuePair<string, string>>() {
            new KeyValuePair<string, string>("key", "<access_key>"),
            new KeyValuePair<string, string>("logfile", "path_To_log/log.txt"),
            //new KeyValuePair<string, string>("binarypath", "/Tools/local/BrowserStackLocal"),
            new KeyValuePair<string, string>("force", "true"),
        };

        browserStackLocal.start(bsLocalArgs);
        Thread.Sleep(15000);

        DesiredCapabilities capability = new DesiredCapabilities();
        capability.SetCapability("browser", "Chrome");
        capability.SetCapability("browser_version", "62.0");
        capability.SetCapability("os", "Windows");
        capability.SetCapability("os_version", "7");
        capability.SetCapability("resolution", "1024x768");
        capability.SetCapability("browserstack.local", "true");
        capability.SetCapability("browserstack.user", "<username>");
        capability.SetCapability("browserstack.key", "<access_key>");

        driver = new RemoteWebDriver(
          new Uri("http://hub.browserstack.com/wd/hub/"), capability
        );
        driver.Navigate().GoToUrl("http://localhost:45691/check");

        Console.WriteLine(driver.Title);

        driver.Quit();
        browserStackLocal.stop();
    }
}
}
