通过 GeckoDriver 的 Firefox 在 Selenium 3.0.1 中的 .Quit() 上抛出异常

Firefox via GeckoDriver throws exception on .Quit() in Selenium 3.0.1

上下文:Firefox 50.0.2 64 位,C#,Visual Studio 2015,Windows Server 2012 R2,Azure,ClearScript.V8.5.4.7,Selenium.Mozilla.Firefox.Webdriver.0.6.0.1 , Selenium.WebDriver.GeckoDriver.Win64.0.11.1

我正在使用 ClearScript 包装用于 JavaScript 的 Selenium 对象,即

    static JScriptEngine JSengine = null;
    ...
    JSengine = new JScriptEngine(WindowsScriptEngineFlags.EnableDebugging | WindowsScriptEngineFlags.EnableJITDebugging);
    ...
    JSengine.AddHostType("CSFirefoxDriver", typeof(FirefoxDriver));
    JSengine.AddHostType("CSFirefoxOptions", typeof(FirefoxOptions));
    JSengine.AddHostType("CSFirefoxDriverService", typeof(FirefoxDriverService));

我使用以下 JS 实例化 Firefox

var driverService = CSFirefoxDriverService.CreateDefaultService();
driverService.FirefoxBinaryPath = "C:\Program Files\Mozilla Firefox\firefox.exe";
driverService.HideCommandPromptWindow = true;
driverService.SuppressInitialDiagnosticInformation = true;
var options = new CSFirefoxOptions();
driver = new CSFirefoxDriver(driverService, options, CSTimeSpan.FromSeconds(30));

匹配的Quit/Dispose代码是

try {
  driver.Quit();
} catch (E) {
  T.Error().Send("driver.Quit() failed.");
}

try {
  driver.Dispose();
} catch (E) {
  T.Error().Send("driver.Dispose() failed.");
}

(T是一个日志对象)

执行 .Quit() 方法调用时,出现以下对话框。

如果我注释掉 .Quit(),那么我会在 .Dispose() 上得到相同的结果。

其他论坛建议在 Firefox 的首选项中关闭硬件加速。这根本没有任何区别。

geckodriver 论坛上也有一个问题声称已修复此问题。现在肯定没修好。

Windows 事件日志在这里不是特别有用,即

我从这里去哪里?在找到修复之前,我可以回退到 PhantomJS。

我遇到了同样的问题,我发现有人发过here。现在您可以降级到 Firefox 48.0.2,直到它被修复。

问题仅在 windows 8.1 上出现(我检查了 win7 和 win10,它工作正常)。所以您应该升级您的 OS 或降级浏览器。

如果使用 driver.quit(),此问题与 webdriver.gecko.driver 有关 我在 selenium-java-3.0.1、FF v 50.1.0、Eclipse Kepler、JDK1.8

上遇到了同样的问题

解决方案:使用 driver.close()

使用这个。杀掉所有firefox的进程和异常进程windows(网上加入2个解决方案):

string sProcessName = "firefox";

            if (driver.Capabilities.BrowserName == sProcessName)
            {
                // Special fix for firefox because of issue https://github.com/mozilla/geckodriver/issues/173
                // Kills all firefox processes

                Process[] oProccesses = null;
                bool bFound = true;

                while (bFound == true)
                {
                    bFound = false;
                    oProccesses = System.Diagnostics.Process.GetProcessesByName(sProcessName);

                    foreach (Process oCurrentProcess in oProccesses)
                    {
                        bFound = true;
                        //oCurrentProcess.Kill();


                        int waitTimeSecs = 2;

                        bool cleanExit = oCurrentProcess.WaitForExit(waitTimeSecs * 1000);
                        if (!oCurrentProcess.HasExited)
                        {
                            oCurrentProcess.CloseMainWindow();
                            System.Threading.Thread.Sleep(2000);
                        }

                        if (!oCurrentProcess.HasExited)
                        {
                            oCurrentProcess.Kill();
                            oCurrentProcess.WaitForExit();
                            // if an exception window has popped up, that needs to be killed too

                            foreach (var process in Process.GetProcessesByName("firefox"))
                            {
                                process.CloseMainWindow();
                                System.Threading.Thread.Sleep(2000);
                                if (!process.HasExited)
                                    process.Kill();
                            }
                        }


                    }
                }
                driver.Quit();
            }
