Handling a popup window using selenium

问题

I have a circumstance in which clicking a link webpage opens a popup window. And after the popup window opens the focus is in the popup window and master window is disabled. And i am unable to get the control transferred to the popup window. Please have a look at the following code.

driver.findElement(By.linkText("Click me")).click();// when this line of code is reached then a popup window opens.

System.out.println("After Clicking me"); // After the popup window opens this line of code is never executed.

I am unable to transfer the control from parent window to popup window. I am aware of the following command.

driver.switchTo().window("popup window");

But its not helping much. please help me.

This is a code i use when i need to work with a following pop-up window, close it and go back to my main window. Of course it has been simplified for the purpose of this answer. It maintains a handle of the original window (main) so it can make a difference between the others.

It requires an explicit WebDriverWait because i did have problems during development that code got run before the window actually got open, so this might not be a ideal condition,

function manipulatePopUp(final WebDriver driver, final WebDriverWait wait) {
    final String mainWindowHandle = driver.getWindowHandle();
    driver.findElement(By.id("linkThatOpensPopUp")).click();

    wait.until(new ExpectedConditions<Boolean>() {
        @Override
        public Boolean apply(WebDriver d) {
            return (d.getWindowHandles().size() != 1);
        }
    });

    for (String activeHandle : driver.getWindowHandles()) {
        if (!activeHandle.equals(mainWindowHandle)) {
            driver.switchTo().window(activeHandle);
        }
    }

    driver.close();
    driver.switchTo().window(mainWindowHandle);
}

driver.findElement(By.linkText("Click me")).click();// when this line of code is reached then a popup window opens.

System.out.println("After Clicking me"); // After the popup window opens this line of code is never executed.

The line of code is never executed because the process is waiting for the popup to be handled.

getWindowHandles() works properly in this situation.

Example:

//handle of the master window before clicking the link
String master = driver.getWindowHandle();

driver.findElement(By.linkText("Click me")).click();

//logic for waiting for the popup, checking the size to become greater than 1 or breaking after sometime to avoid the infinite loop.
int timeCount = 1;

do
{
   driver.getWindowHandles();
   Thread.sleep(200);
   timeCount++;
   if ( timeCount > 50 ) 
   {
       break;
   }
}
while ( driver.getWindowHandles().size == 1 );

//Assigning the handles to a set
Set<String> handles = driver.getWindowHandles();
//Switching to the popup window.
for ( String handle : handles )
{
    if(!handle.equals(master))
    {
         driver.switchTo().window(handle);
    }
}

Now driver is switched to the popup window. If the popup window has a frame then you need to switch to the frame before identifying elements in it.

public class socialSignOn extends masterBaseClassNewSiteStage {

    @Test
    public void testSocialSignOn() throws Throwable {
        openParticularUrl("/my-lfc/join/user-details?user_type=free");

        driver.findElement(By.cssSelector("#socialSignOn > div.left.socialLogin.googleButton")).click();

        String MainWindow = driver.getWindowHandle();

        for (String activeHandle : driver.getWindowHandles()) {
            if (!activeHandle.equals(MainWindow)) {
                driver.switchTo().window(activeHandle);
            }
        }
        driver.findElement(By.cssSelector("#Email")).sendKeys("");
        driver.findElement(By.cssSelector("#next")).click();
        pauseFiveSeconds();
        driver.findElement(By.cssSelector("#Passwd")).sendKeys("");
        driver.findElement(By.cssSelector("#signIn")).click();
        pauseOneSecond();
        driver.switchTo().window(MainWindow);
        pauseTenSeconds();
        closeDriver();
    }
}

// delay : max number of seconds
new WebDriverWait(driver, delay * 1000).until(ExpectedConditions.alertIsPresent());
drive`enter code here`r.switchTo().alert().accept();
