Sometimes learning all the things feels quite overwhelming. This is a streamlined (minimalist) guide to software development with Python. As such it must be opinionated. One tool is chosen over another, not necessarily because it is better but because we need a path forward.
Note: This is in many ways what I am taking away from TestDriven’s The Complete Python Development Guide.
For Linux and Mac machines this is pretty easy. If you are using a Windows machine, you’ll need to install Windows Subsystem for Linux (WSL). For our purposes we’ll be using Ubuntu.
Python Version Management
A language version manager provides a simple way to install and use multiple versions of a language. Node.js has nvm, Ruby has rvm, Python has pyenv.
Python Environment and Dependencies Management
We’ll be using Poetry (the other big player is pipenv).
We’ll use pytest.
- Mocking – Built into pytest.
- Use pytest-mock
- Use pytest monkeypatch
- Code Coverage
- Use pytest-cov (Coverage.py under the hood)
