Selenium Webdriver Switch Window Commands

Some web applications have many frames or multiple windows. Selenium WebDriver assigns an alphanumeric id to each window as soon as the WebDriver object is instantiated. This unique alphanumeric id is called window handle. Selenium uses this unique id to switch control among several windows. In simple terms, each unique window has a unique ID, so that Selenium can differentiate when it is switching controls from one window to the other.

GetWindowHandle Command

Purpose: To get the window handle of the current window.

String  handle= driver.getWindowHandle();//Return a string of alphanumeric window handle

GetWindowHandles Command

Purpose: To get the window handle of all the current windows.

Set<String> handle= driver.getWindowHandles();//Return a set of window handle

SwitchTo Window Command

Purpose: WebDriver supports moving between named windows using the “switchTo” method.

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

Or

Alternatively, you can pass a “window handle” to the “switchTo().window()” method. Knowing this, it’s possible to iterate over every open window like so:

for (String handle : driver.getWindowHandles())

 {

    driver.switchTo().window(handle);

}

Switching between windows with Iterators:

driver.findElement(By.id(“id of the link which opens new window”)).click();

 //wait till two windows are not opened

 waitForNumberofWindowsToEqual(2);//this method is for wait

 Set handles = driver.getWindowHandles();

 firstWinHandle = driver.getWindowHandle(); handles.remove(firstWinHandle);

 String winHandle=handles.iterator().next();

 if (winHandle!=firstWinHandle){

 //To retrieve the handle of second window, extracting the handle which does not match to first window handle

 secondWinHandle=winHandle; //Storing handle of second window handle

//Switch control to new window

 driver.switchTo().window(secondWinHandle);
