## Test Infrastructure

### Fixtures Provided
- `client` - FastAPI test client
- `db_session` - Synchronous SQLAlchemy session
- `test_project` - Pre-created test project
- `test_items` - Pre-created test items
- `test_links` - Pre-created test links

### Database Setup
- SQLite in-memory or file-based
