Python, Selenium & Firefox

Version imprimable

Salut tout le monde

Je me suis mis à utiliser selenium depuis peu (actuellement au stade de l'experimentation) et j'ai besoin de votre aide : un message d'erreur ferme firefox automatiquement, sans afficher la page demandée.

Voici le message d'erreur :

Code:

1

6

8
9
10
11
12
Traceback (most recent call last):

    driver = webdriver.Firefox()
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/selenium/webdriver/firefox/webdriver.py", line 80, in __init__
    self.binary, timeout)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/selenium/webdriver/firefox/extension_connection.py", line 52, in __init__

Et mon code :

Code:

from selenium import webdriver
 
browser = webdriver.Firefox()
browser.get('http://www.python.org')

Peux-tu nous indiquer la version de Selenium et la version de Firefox.
D'après mes recherches, il semble qu'il y ai une incompatibilité de version.

J'utilise les dernières versions connues de chacun d'entre eux, donc selenium 3.0.0b3 et firefox 49.0

As-tu pris en compte cette information :

Citation:

By a quirk of timing, Mozilla have made changes to Firefox that mean that from Firefox 48 you must use their geckodriver to use that browser, regardless of whether you’re using Selenium 2 or 3.

Citation:

At the same time as the Selenium project is shipping Selenium 3.0, Mozilla are changing the internals of Firefox in a way that makes it more stable and secure, but which also makes the community provided Firefox Driver no longer work. As such, if you use Firefox for your testing, you’ll need to use the geckodriver, which is an executable similar to the chromedriver and the Microsoft WebDriver for Edge. You’ll need to start using geckodriver even if you’re using Selenium 2 — the change is in the browser, not Selenium. Please be aware that geckodriver is alpha software, based on the evolving W3C WebDriver standard: everyone’s working flat out to give you the best testing experience they can, but there are undoubtedly some bumps in the road when it comes to testing with Firefox.

Cordialement,
Patrick Kolodziejczyk.

J'ai téléchargé geckodriver mais ça a l'air plus compliqué...
En tout cas ça marche avec la version 47.0 de firefox !
Merci beaucoup
