I hope you know this and already tried, but let you aware if you dont know.

Inorder to interact with any new window first you need to switch to that window.

Each window is identified with a handler. You can get this handler by 

String strWindowHandler=driver.getWindowHandle(); //Current opened browser window handle

Once you get the handle, you to set focus/point your driver to this window.

You can do this by using:

driver.switchTo().Window(strWindowHandler)

To switch between windows you need to use

Set<String> strWindows=driver.getWindowHandlers();

Iterate through each window and act on your required browser window.

Without the above you cannot switch to new window and cannot access any controls on it.

Find below video may help for detailed explanation.

Just add this , when u want to handle the other window.

for(String winHandle : driver.getWindowHandles()){

    driver.switchTo().window(winHandle);

You shared a code snippet that basically is iterating through a set of windows within a loop. What is that going to solve ?

Thanks & Regards

Hi Krishnan,

whenever you want to switch on new window , it will handle the new window and focused on that , then you can perform further operations on new window.

Please take a closer look at your code snippet.

for(String winHandle : driver.getWindowHandles()){
    driver.switchTo().window(winHandle);
}

Lets say getWindowHandles() returns back 12 window handles but you actually had to switch only to the second window.

Now tell me, does your code switch to the second window handle and let me proceed with the next operation (or) does it just switch between all the 12 windows (till the loop ends) and then let me do some operation ?

Thanks & Regards

I got your point , basically this code will not work on handling multiple windows , like you are giving the example of 12 windows.
if you want to handle multiple windows then use this code :

Set < String > s = driver.getWindowHandles(); 

driver.switchTo().window(s.toArray()[0].toString());

// Any operation

driver.close();

driver.switchTo().window(s.toArray()[1].toString());

// Any Operation

driver.close();

driver.switchTo().window(s.toArray()[2].toString());

// Any operation 

This is the best solution , I ever used to handle multiple windows :)

[Jim Evans]

Except that you are assuming there's an order to the handles returned by getWindowHandles(). It's a common mistake, but the handles are explicitly not in any order. In other words, if getWindowHandles() returns N handles, the first handle in the list (handles.get(0)) is not necessarily the first browser window opened, nor is the last handle in the list (handles.get(N - 1)) the most recently opened window. You need to be a little more sophisticated to make sure you're selecting the right window.

Hi Jim, 

That's an interesting fact , even I have not tried this , so may you please tell me how we can handle in this situation ?

[Andreas Tolfsen]

First of all, thanks to Jim for his excellent explanation.

You will either need to keep track of the windows opened yourself so
you can provide a somewhat index-safe list, and to do this you likely
need to apply a diffing technique to what the most recent introduced
window is.

Example in Python code (untested):

original_handles = set(driver.window_handles)

def open_link_in_window(driver):
diff = set(driver.window_handles) - original_handles
if len(diff) > 0:
new_window = diff[0]
driver.switch_to_window(new_window)

is_loaded = driver.execute_script(
"return document.readyState == 'DOMContentLoaded'")
return is_loaded

link = driver.find_element_by_tag_name("a")
link.click()
Wait(driver).until(open_link_in_window)
