selenium java window handle code example

Example 1: multiple windows in selenium

Selenium stays on one window. If you open a window and then 5 tabs popped open,
selenium is focused on the first window
If you are on a new window and you tell selenium to print an element on 
the default window, it will still work even that user’s focus is on the 
new window. Must switch to new window:

    - Use windowHandle()
    - Driver.getWindowHandle()
   - Everytime Selenium opens a browser, it's going to give an index ID
   for the page  called Handles
      - Returns the handle/id of current page (as a string)
      - driver.switchTo().window(string handle)
      - driver.getWindowHandles()  for multiple windows
Returns a Set of window handles
      - Switch using titles:
  	for(string handle: driver.getWindowHandles()){                            
		driver.switchTo().Window(handle)                            
	   		 if(driver.getTitle().equals(targetTitle)
	      			break;

Example 2: how to handle windows in selenium

How do you handle windows?
- We use window handles for handling windows & tabs.

- A window handle is a randomly generated
  unique id for each window.
  
- We can use WindowHandles to switch in
  between different windows.
  
  
SYNTAX =
driver.getWindowHandle;-> returns current window handle
driver.getWindowHandles; return all current opened windows
