- for tests/ and the noxfile.py, type annotations are not strictly
enforced any more
+ this simplifies the way test cases and nox sessions are written
+ for many pytest fixtures, no types are available via a public API
- put fixtures inside the classes the corresponding test cases are
grouped in
- add the following file:
+ src/urban_meal_delivery/console.py => click-based CLI tools
+ tests/test_console.py => tests for the module above
- add a CLI entry point `umd`:
+ implement the --version / -V option
to show the installed package's version
+ rework to package's top-level:
* add a __pkg_name__ variable to parameterize the package name
+ add unit and integration tests
- fix that pylint cannot know the proper order of imports in the
isolated nox session
- add pre-commit and pre-merge hooks:
+ run `poetry run nox -s pre-commit` on staged *.py files
+ run common pre-commit hooks for validations that could not be
achieved with tools in the develop environment so easily
+ run `poetry run nox -s pre-merge` before merges and pushes
- implement the "pre-commit" and "pre-merge" sessions in nox
+ include a little hack to deal with the positional arguments
passed by the pre-commit framework
- provide more documentation on the nox sessions
- use pytest as the base, measure coverage with pytest-cov
+ configure coverage to include branches and specify source locations
+ configure pytest to enforce explicit markers
- add a package for the test suite under tests/
- add a `__version__` identifier at the package's root
+ it is dynamically assigned the version of the installed package
+ the version is PEP440 compliant and follows a strict subset of
semantic versioning: x.y.z[.devN] where x, y, z, and N are all
non-negative integers
+ add module with tests for the __version__
- add a nox session "test" that runs the test suite
- use flake8 to lint pytest for consistent style
- use flake8 as the main and pylint as the auxiliary linter
- install flake8 with the following plug-ins:
+ flake8-annotations => enforce type annotations for functions/classes
+ flake8-black => ensure black would not make any changes
+ flake8-expression-complexity
+ wemake-python-styleguide, which packages the following:
* darglint * flake8-bandit * flake8-broken-line
* flake8-bugbear * flake8-commas * flake8-comprehensions
* flake8-debugger * flake8-docstrings * flake8-eradicate
* flake8-isort * flake8-rst-docstrings * flake8-string-format
* flake8-quotes * pep8-naming
- configure flake8 & friends in a rather explicit and strict way
- isort needed to be downgraded to ^4.3.21 due to a conflict with
pylint and wemake-python-styleguide:
+ provide TODO's to remove the parts that "fix" isort
- use mypy for static type checking
- add a nox session "lint" that runs flake8, mypy, and pylint
- lint all source files
- (auto-)format code with:
+ autoflake => * remove unused imports and variables
* remove duplicate dict keys
* expand star imports
+ black => enforce an uncompromising code style
+ isort => enforce a consistent import style
(complying with Google's Python Style Guide)
- implement the nox session "format" that runs all these tools
- add the following file:
+ setup.cfg => holds configurations for the develop tools
- set up skeletons for all planned nox sessions
- provide a base configuration for all nox sessions
- create two utility functions:
+ _begin() => run commands common to all sessions
+ _install_packages() => install dependencies in nox sessions
respecting the versions pinned in poetry.lock
- add the following file:
+ noxfile.py
- add the following files:
+ .gitignore => ignore poetry's and pyenv's artifacts
+ LICENSE.txt => MIT license as the project is scientific research
+ README.md => rough description of the project
+ poetry.lock
+ pyproject.toml
+ src/urban_meal_delivery/__init__.py => source code package
- use a "src" layout structure:
+ ensure that pytest runs the tests against a packaged and pip
installed version of the source code, not the *.py files in the
project directory
