How to Identify popup window in Selenium Webdriver....

1. First Check whether its popup window or IFrame window by using IE Developer or Find bug tools.

2. If its popup window then use following code :

driver.findElement(By.xpath("")).click();

Set s=driver.getWindowHandles();

This method will help to handle of opened windows other than parent 



Iterator ite=s.iterator();

while(ite.hasNext())

{

String popupHandle=ite.next().toString();

if(!popupHandle.contains(mwh))

{

driver.switchTo().window(popupHandle);

/**/here you can perform operation in pop-up window**

//After finished your operation in pop-up just select the main window again

driver.switchTo().window(mwh);

}

}

This method will help to filter out of all opened windows

1) String parentWindowHandle = browser.getWindowHandle(); // save the current window handle.

WebDriver popup = null;

Iterator windowIterator = browser.getWindowHandles();

while(windowIterator.hasNext()) { 

String windowHandle = windowIterator.next(); 

popup = browser.switchTo().window(windowHandle);

if (popup.getTitle().equals("Google") {

break;

}

}

2) Uncomment code for the same popup,

//action in popup "Google". 

popup.findElement(By.name("q")).sendKeys("Thoughtworks");

//action in popup "Google". 

popup.findElement(By.name("btnG")).submit();"


3) After the popup actions, switch the driver back to the parent window,


browser.close(); // close the popup.

browser.switchTo().window(parentWindowHandle); // Switch back to parent window.

If its IFrame then use following line.

String parentWindowHandle = driver.getWindowHandle(); 

driver.switchTo().Frame(driver.findelement(by.id("iframeid")));
// perform ur actions.
//revert back to parent control

driver.switchTo().window(parentWindowHandle);
