* Testes _backend_ _REST_ baseados no **Pytest**, integrados com Docker, então você pode testar a interação completa da API, independente do banco de dados. Como roda no Docker, ele pode construir um novo repositório de dados do zero toda vez (assim você pode usar ElasticSearch, MongoDB, CouchDB, ou o que quiser, e apenas testar que a API esteja funcionando).

### Documentation pour les tests

La plupart des tests sont en fait effectués par rapport aux exemples de fichiers sources dans la documentation.

Cela permet de s'assurer que :

* La documentation est à jour.
* Les exemples de documentation peuvent être exécutés tels quels.
* La plupart des fonctionnalités sont couvertes par la documentation, assurées par la couverture des tests.
