  • change more_magic to the name of your Project and when the program is called to make a Test Driven Development any time you want

  • type this in the terminal to run the program

    ./makePythonTdd.sh

    ./makePythonTdd.ps1

  • give a name for the PROJECT_NAME variable when the program is called to make a Test Driven Development any time you want. For example typing this command in the terminal in the folder where the program is saved makes a Test Driven Development environment for a project with the name person

    ./makePythonTdd.sh person

    ./makePythonTdd.ps1 person

BONUS: makePythonTdd.sh Pro

Since you are the adventurous type and made it this deep in the book, I have added extra lines that

  • make the project with PROJECT_NAME as the name if you do not give a name

  • make the class name in CapWords format

  • open the test file and source file in your editor

     1#!/bin/bash
 2if [ -z "$1" ] ; then
 3    PROJECT_NAME="PROJECT_NAME"

code src/$PROJECT_NAME.py and code tests/test_$PROJECT_NAME.py work with Visual Studio Code you can change code to use the command for any Integrated Development Environment (IDE) you like
