Handle windows with Selenium:

 There are test cases in which we need to switch between multiple windows, to automate these test cases using selenium we need to use below functions:

1.getWindowHandle(): This function return parent window reference.

2.getWindowHandles() : This function return all windows reference.

3.switchTo().window(Window) : This function used to switch between windows.

Example:

String Parent_Window = driver.getWindowHandle();

for (String Child_Window : driver.getWindowHandles())

{

driver.switchTo().window(Child_Window);

driver.findElement(By.id("appointment")).click();

driver.findElement(By.id("closeAppointment")).click();

driver.close();

}

driver.switchTo().window(Parent_Window);
