Getting Started TDD in 30 Seconds with Python

Quick start to setup python script for Test Driven Development in 30 seconds

Time start!

  1. Install Python virtual environment for human ( yay! ) pipenv

    sudo pip install pipenv
    
  2. create a directory and enter to it

    mkdir my-tdd
    cd my-tdd
    
  3. Activate Python virtual environment, then the tool will automatically create it (if it’s not exist!)

    pipenv shell
    
  4. Install pytest as a dev dependency

    pipenv install pytest --dev
    
  5. create file and test file in any place of the directory

    # in lib.py
    def hello():
    return "hello"

    # in lib_test.py or test_lib.py
    import lib
    def test_hello():
    assert lib.hello() == "hello"
  6. let’s test

    pytest
    

Getting result!

The structure will be like this

lib.py
lib_test.py
Pipfile
Pipfile.lock

Extra! #

You can use automatically test your code when the code's changed using pytest-watch

pipenv install pytest-watch

Let’s fun with TDD

ptw

Time stoppppppppppp!

As I said before, this blog will end within 30 seconds
