Structure for new Python Projects
- Pipenv as packaging tool.
- Make as task runner.
- pylint as source code analyzer.
- pytest as testing framework.
- pytest-mock - Thin-wrapper around the mock package for easier use with py.test.
- pytest-cov - This plugin produces coverage reports.
- pytest-pspec - A pspec format reporter for pytest
- isort - A Python utility / library to sort imports.
In order to make long commands short (got the pun?) this project comes up with a list of built-in make tasks:
It's good a practice to read the Makefile and understand what each task does, and so it's possible to one improve the task for the one's better using.
$ make
Usage:
make <target>
Targets:
build Create wheel from source
clean Remove build files
format Format with black
