- 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
