- use SQLAlchemy (and PostgreSQL) to model the ORM layer
- add the following models:
+ Address => modelling all kinds of addresses
+ City => model the three target cities
+ Courier => model the UDP's couriers
+ Customer => model the UDP's customers
+ Order => model the orders received by the UDP
+ Restaurant => model the restaurants active on the UDP
- so far, the emphasis lies on expression the Foreign Key
and Check Constraints that are used to validate the assumptions
inherent to the cleanded data
- provide database-independent unit tests with 100% coverage
- provide additional integration tests ("e2e") that commit data to
a PostgreSQL instance to validate that the constraints work
- adapt linting rules a bit
- add the following file:
+ src/urban_meal_delivery/_config.py
- a config module is created holding two sets of configurations:
+ production => against the real database
+ testing => against a database with test data
- the module is "protected" (i.e., underscore) and imported at the
top level via a proxy-like object `config` that detects in which of
the two environments the package is being run
- 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
- 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
