How can I handle selenium and geckodriver install error? - django

Question

I ran the following code by installing selenium and django module.
from selenium import webdriver
browser = webdriver.Firefox()
browser.get('http://localhost:8000')
assert 'Django' in browser.title
For the selenium module, I need geckodriver for firefox browser.
So, I installed geckodriver by different ways - 1. npm, 2. brew, 3. direct install (download from here and move it to /usr/local/bin or /usr/bin. All the ways did not work for the above test code.
I got the following error message:
Traceback (most recent call last):
File "functional_tests.py", line 3, in <module>
browser.get('http://localhost:8000')

Please let me know what the problem is..

Answer 1

I think you need a gecko driver as well.
You can download from here
and put it into a folder, preferably where you have your .py files
and then use it like this :-
from selenium import webdriver
driver = webdriver.Firefox(executable_path = "D:\geckodriver.exe")
driver.maximize_window()
browser.get('http://localhost:8000')
assert 'Django' in browser.title
PS :
executable_path = 'full file path to your gecko driver'
