makePythonTdd.sh

makePythonTdd.sh program

• Here is the makePythonTdd.sh program from how to make a python test driven development environment

  #!/bin/bash
  PROJECT_NAME=$1
  mkdir $PROJECT_NAME
  cd $PROJECT_NAME
  mkdir src
  touch src/$PROJECT_NAME.py
  mkdir tests
  touch tests/__init__.py
  
  echo "import unittest
  
  
  class Test$PROJECT_NAME(unittest.TestCase):
  
      def test_failure(self):
          self.assertFalse(True)
  
  
  # Exceptions seen
  # AssertionError
  " > tests/test_$PROJECT_NAME.py
  
  python3 -m venv .venv
  source .venv/bin/activate
  python3 -m pip install --upgrade pip
  echo "pytest-watch" > requirements.txt
  python3 -m pip install --requirement requirements.txt
  pytest-watch
  

• use chmod to make the program executable

  chmod +x makePythonTdd.sh
  

• 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 makePythonTdd.sh is saved makes a Test Driven Development environment for a project with the name person

  ./makePythonTdd.sh person

BONUS: makePythonTdd.sh Plus

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

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

IFS='_' read -r -a words <<< "$PROJECT_NAME"
IFS=''
CLASS_NAME="${words[*]^}"

mkdir -p $PROJECT_NAME/{src,tests}
cd $PROJECT_NAME
touch src/$PROJECT_NAME.py tests/__init__.py

echo "import unittest


class Test$CLASS_NAME(unittest.TestCase):

    def test_failure(self):
        self.assertFalse(True)


# Exceptions seen
# AssertionError
" > tests/test_$PROJECT_NAME.py

code src/$PROJECT_NAME.py
code tests/test_$PROJECT_NAME.py

python3 -m venv .venv
source .venv/bin/activate
python3 -m pip install --upgrade pip
echo "pytest-watch" > requirements.txt
python3 -m pip install --requirement requirements.txt
pytest-watch

this works with Visual Studio Code you can change it to use the command for any Integrated Development Environment (IDE) you like
