Test-Driven Development with Python

These are my notes from the book Test-Driven Development with Python.

I've used the book as a guide, and deviated occasionally.

Prerequisites and Assumptions

• The book uses Python 3.6 and Django 1.11.
• I'm using Python 3.7, Django 1.11, macOS 10.15, and Homebrew 2.2.
• "venv" is the general convention used globally.

First, install dependencies and create the environment.

# Install Homebrew.
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

# Install the project dependencies.
brew install python3
brew install geckodriver
brew cask install firefox

# Create a Git repository.
git init ~/src/myproject
cd ~/src/myproject

# Create a virtual environment, in the directory "venv".
python3 -m venv virtualenv venv

# Create a .gitignore file.
echo '*.log' >> .gitignore
echo '*.pyc' >> .gitignore
echo '__pycache__' >> .gitignore
echo 'db.sqlite3' >> .gitignore
echo 'venv' >> .gitignore
git add .gitignore

# Commit the .gitignore file.
git commit -m "Add a .gitignore file."

For development and testing, activate virtualenv with this command:

source venv/bin/activate

Once you've activated the virtualenv, install Django & Selenium:

pip install "django<1.12" "selenium<4"

When you're done with development and testing, deactivate virtualenv:

deactivate

Chapter 1: Getting Django Set Up Using a Functional Test

Create a new Django project:

django-admin startproject myproject .

Start a web server:

python manage.py runserver

Run my functional tests.

python functional_tests.py
