imho it’s recommended to solve things without 3rd party packages (which might possible be neglected (no more security updates) or even hijacked after some time)

it is sometimes agreed upon to extend python’s capabilities with 3rd party packages like psutil (for system and process monitoring)

how to install pip (python package manager) (github src 99% python):

# tested for debian + ubuntu
su - root
apt update
# should work
apt install pip
# but more correct, package is called
apt -y install python3-pip

apt show python3-pip

Description: Python package installer

pip is the Python package installer.

It integrates with virtualenv
+ doesn't do partial installs
+ can save package state for replaying
+ can install from non-egg sources,
+ and can install from version control repositories.

This is the Python 3 version of the package.

search for a package here https://pypi.org/

AS NON ROOT USER (NO ROOT REQUIRED) install a package:

pip install packagename

list all installed packages:

pip list|less

update all packages:

# strange enough there is no pip3 update && pip3 upgrade, but a rather complex construct must be used?
pip3 list --outdated --format=freeze | grep -v '^\-e' | cut -d = -f 1 | xargs -n1 pip3 install -U

getting started with robot + selenium gui testing framework

as non-root user: install those 3 packages

pip install robotframework
pip install robotframework-seleniumlibrary
pip install webdrivermanager

wget https://github.com/mozilla/geckodriver/releases/download/v0.35.0/geckodriver-v0.35.0-linux64.tar.gz

tar fxvz geckodriver-v0.35.0-linux64.tar.gz

chmod +x geckodriver

# as root
ln -sv /home/user/software/geckodriver /usr/local/bin/

# log off root
Ctrl+D

# continue non-root

create test script to test if selenium works

vim selenium_test.py

with this content

# does work
from selenium import webdriver
import time
from time import sleep
driver = webdriver.Firefox()
driver.get("http://dwaves.org")
time.sleep(8)
driver.quit()
print("test success")

run it:

python3 ./selenium_test.py

if this error pops up: Your Firefox profile cannot be loaded. It may be missing or inaccessible.

it is because firefox was installed via snap and not apt

uninstall it via snap and re-install it with apt

su - root
snap remove firefox;

install -d -m 0755 /etc/apt/keyrings;

wget -q https://packages.mozilla.org/apt/repo-signing-key.gpg -O- | sudo tee /etc/apt/keyrings/packages.mozilla.org.asc > /dev/null

echo "deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt mozilla main" | sudo tee -a /etc/apt/sources.list.d/mozilla.list > /dev/null;

echo '
Package: *
Pin: origin packages.mozilla.org
Pin-Priority: 1000

Package: firefox*
Pin: release o=Ubuntu
Pin-Priority: -1' | sudo tee /etc/apt/preferences.d/mozilla;

apt update && sudo apt remove firefox;

apt install firefox;
# try re running the test
python3 ./selenium_test.py

if the dev user sees the website opening and browser closing after 8 sec

celebrate! 😀

what should also work…

  • open website
  • enter “selenium” into search textinput
  • hit enter

create script

vim ./selenium_test_submit_form.robot
# test_suite.robot v1.0
# open duckduckgo in firefox browser (installed via apt not snap)
# enter "selenium" in search field
# submit the form
*** Settings ***
Library    SeleniumLibrary

*** Variables ***
${SEARCH_TERM}    selenium

*** Test Cases ***
Open Dwaves And Search selenium
    Open Browser    https://dwaves.org    Firefox
    Input Text      name=s                ${SEARCH_TERM}
    Submit Form     searchform
    Sleep           5 seconds
    Close Browser

*** Test Cases ***
Open DuckDuckGo And Search Selenium
    Open Browser    https://duckduckgo.com  Firefox
    Input Text      name=q                  ${SEARCH_TERM}
    Submit Form     searchbox_homepage

WARNING! THE MASSIVE AMOUNTS OF SPACES (AT LEAST 4?) IS ON PURPOSE AND IT MIGHT NOT RUN WITHOUT AT LEAST 4 SPACES!

it might be useful to get more verbose output in a specified dir:


mkdir output
robot -d output --loglevel DEBUG selenium_test_submit_form.robot

nokia’s eclipse red vs vscode extension

long story short:

vscode:
[+] step debugging script.robot works
[+] follow variable definition with ctrl key works
eclipse2020 or eclipse2024+red:
[-] not developed since 2020 (probably because it is in competition with vscode and M$ bought nokia in 2014)
[-] editor did not work yet (tried 2024 version, tried 2020 version with this url https://sourceforge.net/projects/red-robot-editor/files/)
