I will show you how to run selenium tests without a ton of tools in your machine. This was a result of https://stackoverflow.com/questions/67090130

Introduction

Commonly to run selenium tests, the developer has problems with its machine due its pre-installed browsers and a ton of ancient tools installed on that machine

Docker

I will show you how to run a test with docker, so your host machine could have any browser and the automation will run on another browser. After the test, everything will be deleted, so you machine will continue clean and virginal

Steps

In the host execute this

xhost +

launch the container

docker run \
--rm \
-it \
--privileged \
--env DISPLAY=unix$DISPLAY \
-v $XAUTH:/root/.Xauthority \
-v /tmp/.X11-unix:/tmp/.X11-unix \
python:latest bash

Inside of container, download firefox, geckodriver, some tools

apt-get update && apt-get install -y wget bzip2 libxtst6 libgtk-3-0 libx11-xcb-dev libdbus-glib-1-2 libxt6 libpci-dev

mkdir /browsers
curl https://ftp.mozilla.org/pub/firefox/releases/61.0/linux-x86_64/en-US/firefox-61.0.tar.bz2 -o /browser/firefox-61.0.tar.bz2
tar xvf firefox-61.0.tar.bz2 -C /browsers

mkdir /drivers/
curl -L https://github.com/mozilla/geckodriver/releases/download/v0.32.0/geckodriver-v0.32.0-linux64.tar.gz -o /drivers/geckodrive.tar.gz
tar -xzvf /drivers/geckodrive.tar.gz -C /drivers/

create a folder and add this code /code/app.py

from selenium import webdriver
from selenium.webdriver.firefox.options import Options
 
options = Options()
options.binary_location = '/browsers/firefox'
driver = webdriver.Firefox(executable_path='/drivers/geckodrive', options=options)
driver.get("https://jrichardsz.github.io/")
get_title = driver.title
print(get_title)
driver.close()

note the firefox binary and geckodriver location

asdd its /code/requirements.txt

selenium==4.7.2

finally execute

cd /code/
pip install -r requirements.txt
python app.py

You should see a log like this and firefox will open and disappear after the test
