What is a common real-life example of handling multiple pages in web testing?

Testing a login flow where clicking a link opens a new tab for authentication, then returning to the main page to verify login success.

Which Selenium method returns all open window handles?

B driver.get_window()

C driver.switch_to.window()

D driver.current_window

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

A driver.open_tab(new_handle)

B driver.switch_to.window(new_handle)

C driver.get(new_handle)

D driver.change_tab(new_handle)

What happens if you try to interact with a page element without switching to its window?

A The element is found automatically

B Nothing happens, test passes

C The browser closes

D Selenium throws an error because it controls the wrong window

Selenium commands act on the current window. If you don't switch, it can't find elements on other windows.

Which of these is NOT a good practice when handling multiple pages?

A Ignoring window handles and continuing blindly

B Closing windows you no longer need

C Storing window handles for later use

Ignoring window handles can cause Selenium to act on the wrong window, leading to test failures.
