"""
|
|
End-to-end tests for the OpenAPI-first model CRUD example app.
|
|
|
|
These tests validate that all CRUD operations behave correctly
|
|
against the in-memory mock data store using Pydantic models.
|
|
|
|
The tests assume:
|
|
- OpenAPI-first route binding
|
|
- Pydantic model validation
|
|
- In-memory storage (no persistence guarantees)
|
|
- Deterministic behavior in a single process
