Handling Windows Using Selenium

In automation there are many situations where we need to handle multiple windows.

Generally multiple windows will open when we perform any click action on a link or any button/ web-element etc based on the application behavior.
Selenium webdriver get all the window sessions which are opened through automation(driver instance).

Internally webdriver assigns an uniques alphanumeric id to each and every window when WebDriver object is instantiated.

By using this unique alphanumeric id, Selenium can differentiate when it is switching controls from one window to the other.

How to handle and get the current window :

String parentWindow=driver.getWindowHandle();//Return uniqueId value

How to get all the open windows:

Set windows=driver.getWindowHandles();//Return a set of unique alphanumeric values of all the windows.
for(String windowName : windows)
{
driver.switchTo().window(windowName);//Switch to child window name
//Perform your desired selenium actions
driver.close();//closing the child Window
}

How to switch to Parent Window:

driver.switchTo().window(parentWindow);//Switch back to the parent window

How to switch to window based on window title:

String windowTitle=”Google”;
Set windows=driver.getWindowHandles();//Return a set of unique alphanumeric values of all the windows.

for(String windowName : windows)
{
   driver.switchTo().window(windowName);//Switch to child window name
   if(driver.getTitle().equalsIgnoreCase(windowTitle)
     {
         //Perform your desired actions
      }
   //Close the child windowName
   driver.close();
}
driver.switchTo().window(parentWindow);//Switch back to the parent window

Complete Code:

String windowTitle="Google";
String parentWindow=driver.getWindowHandle();//Return a unique id value
Set windows=driver.getWindowHandles();//Return a set of unique alphanumeric values of all the windows.
for(String windowName : windows)
{
  driver.switchTo().window(windowName);//Switch to child window name
  if(driver.getTitle().equalsIgnoreCase(windowTitle))
    {
        //Perform your desired actions
      }
  //Close the child windowName
  driver.close();
}
driver.switchTo().window(parentWindow);//SwitchBack to the Parent-window
