Python environment setup in Selenium Python

Introduction

Setting up Python environment helps you write and run test scripts easily. It prepares your computer to use Python and Selenium for testing websites.

When you want to start writing automated tests for a website.

When you need to install tools to control a browser with Python.

When you want to practice Selenium testing on your computer.

When you need to manage Python packages for testing.

When you want to run your test scripts without errors.

Syntax

Selenium Python

python -m venv env
source env/bin/activate  # On Mac/Linux
env\Scripts\activate.bat   # On Windows
pip install selenium

python -m venv env creates a new folder named env for your Python environment.

Use source env/bin/activate on Mac/Linux or env\Scripts\activate.bat on Windows to start using this environment.

Examples

This creates and activates a Python environment called mytestenv and installs Selenium inside it.

Selenium Python

python -m venv mytestenv
source mytestenv/bin/activate
pip install selenium

On Windows, activate the environment and install a specific Selenium version.

Selenium Python

env\Scripts\activate.bat
pip install selenium==4.10.0

Sample Program

This simple script opens Chrome, goes to example.com, prints the page title, then closes the browser.

Selenium Python

from selenium import webdriver

# Start Chrome browser
browser = webdriver.Chrome()

# Open a website
browser.get('https://example.com')

# Print page title
print(browser.title)

# Close browser
browser.quit()

Important Notes

Make sure you have ChromeDriver installed and it matches your Chrome browser version.

Activate your Python environment every time before running tests to use the right packages.

Use pip freeze to see installed packages and their versions.

Summary

Python environment setup creates a safe space for your test tools.

Activate the environment before installing or running Selenium tests.

Install Selenium to control browsers for automated testing.
