Request: Add notes about where to put unit tests

I did some Googling. None of the pages have very good explanations of where to put your unit test files.

Also, AFAIK (I am a Python newbiew) there are some drawbacks to <project_root>/test/ about importing. Might need to modify PYTHONPATH during unit test runs.

Also, please talk about why init.py is important for unit tests. A few places recommend it... but I thought it was dead in Python3.

Aucun fichier cible ni aucun test n’est indiqué. Commencez par examiner les discussions liées sur les bonnes pratiques de pytest et le packaging, puis trouvez la documentation pertinente sur les tests. La tâche sera considérée comme terminée lorsque seront expliqués l’emplacement des fichiers de test, les considérations relatives aux imports/PYTHONPATH et le rôle de init.py dans Python 3.
