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

Good bye, see you

P.S. fastest blogging ever 🙏
