网络驱动程序间歇性地引发超时异常.对远程 Web 驱动程序服务器的 URL 的 HTTP 请求

从今天开始，我的测试开始在IE和Firefox上偶尔失败。所有的失败都给了我这个例外。今天早上我在VS2013，Nunit 3.0.1，IEDriver 2.45.0.0，Selenium.Support和Selenium.WebDriver 2.48.2。我认为这是因为我的软件包已过时并更新Selenium.Support并Selenium.Webdriver 2.52.0.例外继续间歇性地困扰着我的测试。唯一似乎与这些例外一致的是它们都是由

wait.Until(ExpectedConditions.someCondition(element));

任何帮助都会很棒 我对 webdriver 相对较新，并且对代码概念有初学者级别的了解，我很乐意提供额外的信息，这个问题已经让我倒退了一天，不能失去更多。帮我堆叠溢出你是我唯一的希望。

今天 3/

7 我的测试没有像周四 （3/4） 那样遇到这个异常，今天早上当我的测试等待弹出窗口时，我遇到了一次。这是这条线 popupWindowHandle = finder.Click(NewListingPage.ImageSelectionPopupElement);

@PankajDubey 这是我所有等待方法的片段。我在这里使用显式等待吗？

public void WaitForElementVisible(IWebDriver driver, By element)
{
    try
    {
        WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(90));
        wait.Until(ExpectedConditions.ElementIsVisible(element));
    }
    catch (WebDriverTimeoutException)
    {
        TakeScreenshot(Driver);
        Console.Write("Test failed trying to wait for this element " + element.ToString() + " to be visible ");
    }
}

@Pankaj - 所以在我的OneTimeSetup中，我按照建议将隐含的等待时间增加到 5 秒。当我运行测试时，他们未能找到屏幕上的元素。测试在ClickViewScheduled()方法上反复失败。

        ListingDonePage.WaitForElementVisible(Driver, ListerDonePageModel.ViewScheduledSelector);
        var ScheduledListingPage = ListingDonePage.ClickViewScheduled();

这是ClickViewScheduled()的定义。这对我来说很奇怪，因为在上一行中，它使用我在上面发布的等待方法等待元素的可见性。所以它"找到"了该行中的元素，然后找不到它进行点击？

    public ScheduledListingsPageModel ClickViewScheduled()
    {
        ViewScheduledElement.Click();
        return new ScheduledListingsPageModel(Driver);
    }
