Q: Handle a popup in selenium web driver using c# ?

When I click on a button on a page, a popup is displayed. This is not a windows popup. It is the application popup.. The popup I get in my application is similar to the one i have shown in the image with a X button. now How do I move the driver control to the popup and then click on the close button available on the popup and then move back my control back to the original page..

I have to do this using Selenium WebDriver and C#.

A1: You need to do the following...

·         Loop through the windows and find the desired window

·         Switch to the windows

·         Find the button in the current window and click the same

Here is the sample code in C#

foreach (string handle in browser.WindowHandles)

        {

            IWebDriver popup = driver.SwitchTo().Window(handle);

            if (popup.Title.Contains("popup title"))

            {

              break;

            }

        }

IWebElement closeButton = driver.FindElement(By.Id("closeButton"));

closeButton.Click();

A2: The example you have shown is not a popup, but a simple DHTML window. To access the X of the example you have provided, you could use: driver.findElementBy(By.id("profile-tooltip-closebtn")).click().

A3: You can try

driver.switchTo().frame(0);

Q2: WebDriver i am trying to use isElementPresent but error shows not exist in the current context

 I am new to WebDriver and writing this code in C# Visual Studio (code snippet below) I am verifying if a text field is present on the home page using IsElementPresent. I get the error The name IsElementPresent does not exist in the current context. What am i doing wrong?

using System;

using System.Text;

using System.Text.RegularExpressions;

using System.Collections.Generic;

using System.Threading;

using System.Linq;

using NUnit.Framework;

using OpenQA.Selenium;

using OpenQA.Selenium.Firefox;

using OpenQA.Selenium.Support.UI;

namespace Homepage_check2

{

    [TestFixture]

    public class Driver

    {

        IWebDriver driver;

        [SetUp]

        public void Setup()

        {

            // Create a new instance of the Firefox driver

            driver = new FirefoxDriver();

        }

        [TearDown]

        public void Teardown()

        {

            driver.Quit();

        }

        [Test]

        public void homepage()

        {

            //Navigate to the site

            driver.Navigate().GoToUrl("http://www.milkround.com");

           Assert.IsTrue(IsElementPresent(By.Id("ctl00_uxToolbar_uxQueryTextBoxToolbar")));

        }

        catch

        {

            //verificationErrors.Append(e.Message);

        }

        }

    }

}

A1: Where does "IsElementPresent" come from? I have never seen that used in WebDriver.

In WebDriver you need to do wrap a try catch around the findElement method.

e.g

Boolean elementDisplayed;

try {

WebElement element = driver.findElement(By.Id("ctl00_uxToolbar_uxQueryTextBoxToolbar"));

elementDisplayed = element.displayed; 

}

catch (NoSuchElementException e) {

elementDisplayed = false;

}

Obviously you can wrap this in a helper method of some kind of perhaps add it to the WebDriver classes.

I'll leave that to you, but this is the general idea
