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

Thanks guy, any question, pls comment

Good bye, see you

P.S. fastest blogging ever 🙏
