Summary

Set up a small FastAPI todo service. Used SQLModel for the DB layer (SQLAlchemy + Pydantic in one), and pytest for the test harness. Five endpoints: list, create, get, update, delete.

Start a FastAPI project. Use SQLModel for models and SQLite for dev. Expose CRUD on /todos.

Turn 1 — Assistant

Created the project layout:

- app/main.py — FastAPI instance
- app/models.py — SQLModel Todo class
- app/db.py — engine + get_session dependency
- app/routes/todos.py — router
- tests/test_todos.py — pytest cases

Tools used in this turn:
- Write: app/main.py (5-line preview)
- Write: app/models.py (5-line preview)
- Write: app/db.py (5-line preview)
- Write: app/routes/todos.py (5-line preview)
- Write: tests/test_todos.py (5-line preview)

Turn 2 — User

Run the tests.

Turn 2 — Assistant

 

All five CRUD tests pass. Each one spins up a fresh in-memory SQLite, so they're fully isolated.

Tools used in this turn:
- Bash: pytest tests/ -v — exit 0
