Why is it important to switch back to the original window after working with a new window?

Switching back ensures your test continues in the correct window context and avoids errors when interacting with elements in the original window.

Which Selenium method switches control to a different browser window?

A driver.switch_to.window(handle)

B driver.get_window(handle)

C driver.change_window(handle)

D driver.open_window(handle)

The correct method to switch control to another window is driver.switch_to.window(handle).

What does driver.window_handles return?

A The title of the current window

B The current window handle

C A list of all open window handles

D The URL of the current window

driver.window_handles returns a list of all open window handles.

If you want to switch back to the original window, what should you do?

A Use <code>driver.switch_to.window(original_handle)</code>

B Close the current window

C Use <code>driver.refresh()</code>

D Open a new window

You switch back by calling driver.switch_to.window(original_handle) where original_handle is the saved handle of the first window.

What exception might occur if you try to interact with elements in a window you haven't switched to?

C ValueError

D IndexError

Trying to interact with elements in a non-focused window usually causes a NoSuchElementException.

Why is it useful to store the original window handle before switching?
