OpenQA.Selenium.NoSuchElementException未处理C#另一个网站

我是硒的新手,目前正在研究硒的工作原理.开始将其用于ASP.NET应用程序,我正在使用C#Selenium驱动程序,IE驱动程序服务器(32位,因为它比64位快)

我导航到一个应用程序,然后单击一个链接,该链接会将我带到另一个网站,我必须在其中找到一个文本框并清除它,然后输入一些文本(SendKeys),然后单击一个按钮.

当它从主网站转到另一个网站时,找不到元素(我尝试使用by.ID和by.Name).我确保该元素在网页上可用.作为推荐,我使用了ImplicitlyWait,但没有运气,尝试了thread.sleep()没有运气.测试是否需要在最初启动的网站上进行？..以下是我的代码段..请帮助我.

using System.Threading;

namespace mySelenium
{
    class Program
    {
    private static void Main(string[] args)
    {
        IWebDriver driver = new InternetExplorerDriver(@"C:\Users\msbyuva\Downloads\IEDriverServer_Win32_2.45.0\");
        driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(10));

        driver.Navigate().GoToUrl("http://MyorgName.org/Apps/Sites/2015/login.aspx");

        IWebElement userNameTxtBox = driver.FindElement(By.Id("ContentPlaceHolder1_Login1_UserName"));
        userNameTxtBox.SendKeys("MSBYUVA");

        IWebElement passwordTxtBox = driver.FindElement(By.Id("ContentPlaceHolder1_Login1_Password"));
        passwordTxtBox.SendKeys("1234");

        var myButton = driver.FindElement(By.Id("ContentPlaceHolder1_Login1_LoginButton"));
        myButton.Click();

        var EMailLink = driver.FindElement(By.LinkText("Email Testing Link"));
        EMailLink .Click();

        //Thread.Sleep(10000);

// -- HERE IT IS THROWING ERROR (ANOTHER WEBSITE AFTER CLICKING HYPERLINK)

    var toEmailAddress  = driver.FindElement(By.Name("ctl00$ContentPlaceHolder1$txtTo"));
                toEmailAddress.Clear();
                toEmailAddress.SendKeys("[email protected]");


            var chkEmailAttachment = driver.FindElement(By.Name("ctl00$ContentPlaceHolder1$ChkAttachMent"));
            chkEmailAttachment.Click();

            var sendEmailButton = driver.FindElement(By.Id("ctl00_ContentPlaceHolder1_BtnSend"));
            sendEmailButton.Click();
        }
    }
}

解决方法:

您需要切换到新打开的窗口并为其设置焦点,以便向其发送任何命令

string currentHandle = driver.CurrentwindowHandle;

driver.SwitchTo().Window(driver.WindowHandles.ToList().Last());

在新打开的窗口完成后(根据需要)

driver.Close();
driver.SwitchTo().Window(currentHandle );

更完美地使用PopupWindowFinder类

string currentHandle = driver.CurrentwindowHandle;
PopupWindowFinder popUpWindow = new PopupWindowFinder(driver);
string popupWindowHandle = popUpWindow.Click(EMailLink );
driver.SwitchTo().Window(popupWindowHandle);

//then do the email stuff

 var toEmailAddress  = driver.FindElement(By.Name("ctl00$ContentPlaceHolder1$txtTo"));
                toEmailAddress.Clear();
                toEmailAddress.SendKeys("[email protected]");


            var chkEmailAttachment = driver.FindElement(By.Name("ctl00$ContentPlaceHolder1$ChkAttachMent"));
            chkEmailAttachment.Click();

            var sendEmailButton = driver.FindElement(By.Id("ctl00_ContentPlaceHolder1_BtnSend"));
            sendEmailButton.Click();
        }
    }
}

//closing pop up window
driver.Close();
driver.SwitchToWindow(currentHandle);
