Python Question

launch selenium from python on ubuntu

I have the following script

from selenium import webdriver

browser = webdriver.Firefox()

assert 'Django' in browser.title

I get the following error

$ python3 functional_tests.py
Traceback (most recent call last): File "functional_tests.py", line 3, in <module>
browser = webdriver.Firefox() File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/firefox/webdriver.py", line 80, in __init__

"The browser appears to have exited " selenium.common.exceptions.WebDriverException: Message: The browser appears to have exited before we could connect. If you specified a log_file in the FirefoxBinary constructor, check it for details.

pip3 list
selenium (2.53.6)

firefox -v
Mozilla Firefox 47.0

Answer Source

The last version of Firefox is not working properly with selenium. Try with 46 or 45.

You can download here: ftp.mozilla.org/pub/firefox/releases

or sudo apt-get install firefox=45.0.2+build1-0ubuntu1
