Comment faire pour ouvrir une nouvelle fenêtre ou un onglet de webdriver (Python)?

Après des tonnes de recherches sur google, je suis tombé sur ce qui fonctionne pour moi sous Firefox et qui est si simple (élégant, peut-être?) pour être presque risible. Ici, il est:

>>> from selenium import webdriver
>>> driver = webdriver.Firefox()
>>> driver.execute_script("window.open('');")  <--- JAVASCRIPT!

J'ai rencontré le même problème, et je n'étais pas vraiment satisfait avec les autres solutions que j'ai trouvé, j'ai donc fait un gestionnaire de contexte pour faire la manipulation. Cela permet:

with link_in_new_window(driver, link_element):
    driver.foo()  # this is in the new window opened from the link
driver.foo()  # this is back in the original window

.., que je trouve très pratique.

from contextlib import contextmanager
from selenium.common import exceptions
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys
# Fundamentally, this shift-clicks to open a new window, and
# hits ctrl-w to close it when done, using ActionChains.
@contextmanager
def link_in_new_window(driver, element):
"""Open a clickable element in a new window for this context
This opens a clickable element in a new window, and switches
`driver` to that window for the duration of the context.  
The window is closed afterward, and the driver switched back
to the original window.
If the 'as' clause is used, the handle of the parent (original)
window is provided as the value.
Selenium doesn't provide a useful interface to firefox's tabs
due to some technical complications, so we use new windows
instead of new tabs. The memory hit isn't too significant.
:type driver: selenium.webdriver.Firefox
:type element: selenium.webdriver.remote.webelement.WebElement
:returns: Parent's Window Handle

known_handles = set(driver.window_handles)
original_handle = driver.current_window_handle
action = ActionChains(driver)
# Open link in new window (shift-click element)
# Sometimes, shift would be ignored. move_to_element helped.
action.move_to_element(element)
.key_down(Keys.SHIFT)
.click(element)
.key_up(Keys.SHIFT)
.perform()
# Find the new window handle.  ..anyone know a better way?
timeout = time.time() + 10
new_handles = set(driver.window_handles) - known_handles
while time.time() < timeout and not new_handles:
new_handles = set(driver.window_handles) - known_handles
time.sleep(0.5)

# close window, if it still exists (ctrl-w)
