### Test Fixtures Added
|
|
|
|
**Portfolio Data Fixtures:**
|
|
- `portfolio_data` - Default PAPER portfolio
|
|
- `live_portfolio_data` - LIVE portfolio data
|
|
- `backtest_portfolio_data` - BACKTEST portfolio data
|
|
- `test_portfolio` - Created PAPER portfolio instance
|
|
- `live_portfolio` - Created LIVE portfolio instance
|
|
- `multiple_portfolios` - 5 portfolios with varied types
|
|
- `another_user` - Alias for second_user (user isolation testing)
|
|
- `valid_currencies` - List of valid ISO 4217 codes
|
|
- `invalid_currencies` - List of invalid currency codes
|
|
|
|
### Test Execution Status
|
|
|
|
**RED Phase (TDD):**
|
|
```bash
|
|
$ pytest tests/unit/api/test_portfolio_model.py --tb=line -q
|
|
33 skipped in 1.43s
|
|
|
|
$ pytest tests/integration/api/test_portfolio_integration.py --tb=line -q
|
|
18 skipped in 0.75s
|
|
```
|
|
|
|
All tests are **correctly skipped** because the Portfolio model has not been implemented yet.
|
|
This confirms proper TDD RED phase - tests written BEFORE implementation.
|
|
|
|
### Coverage Areas
|
|
|
|
1. **CRUD Operations** - Create, Read, Update, Delete
|
|
2. **Enum Validation** - PortfolioType (LIVE, PAPER, BACKTEST)
|
|
3. **Decimal Precision** - Decimal(19,4) for monetary values
|
|
4. **Unique Constraints** - (user_id, name) uniqueness
|
|
5. **Cascade Delete** - Portfolio deletion when user deleted
|
|
6. **Currency Validation** - 3-letter ISO codes
|
|
7. **Relationships** - User <-> Portfolio bidirectional
|
|
8. **Edge Cases** - Long names, unicode, empty values, negatives
|
|
9. **Query Operations** - Filter, order, aggregate
|
|
10. **Lifecycle Management** - Create, update, deactivate, delete
|
|
11. **Multi-currency** - Different currencies per portfolio
|
|
12. **Concurrency** - Bulk operations, concurrent updates
|
|
|
|
### Next Steps for Implementation Team
|
|
|
|
1. Create `spektiv/api/models/portfolio.py` with:
|
|
- `PortfolioType` enum (LIVE, PAPER, BACKTEST)
|
|
- `Portfolio` model class with all fields
|
|
- Relationships to User model
|
|
- Constraints and validators
|
|
|
|
2. Update `spektiv/api/models/__init__.py` to export Portfolio
|
|
|
|
3. Run tests again - they should transition from SKIP to FAIL/PASS
|
|
|
|
4. Target: 95%+ test pass rate after implementation
|
|
|
|
### Test Quality Metrics
|
|
|
|
- **Test Coverage**: 51 comprehensive tests
|
|
- **Test Isolation**: Each test independent via db_session rollback
|
|
- **Edge Cases**: 10+ edge case scenarios
|
|
- **Security**: SQL injection prevention via SQLAlchemy ORM
|
|
- **Performance**: Bulk operation tests included
|
|
- **Documentation**: Every test has descriptive docstring
|
|
|
|
### Model Requirements (from tests)
|
|
|
|
```python
|
|
class PortfolioType(str, Enum):
|
|
LIVE = "LIVE"
|
|
PAPER = "PAPER"
|
|
BACKTEST = "BACKTEST"
|
|
|
|
class Portfolio(Base, TimestampMixin):
|
|
__tablename__ = "portfolios"
|
|
|
|
id: Mapped[int] - Primary key
|
|
user_id: Mapped[int] - Foreign key to users
|
|
name: Mapped[str] - String(255), not null
|
|
portfolio_type: Mapped[PortfolioType] - Enum, not null
|
|
initial_capital: Mapped[Decimal] - Decimal(19,4), not null
|
|
current_value: Mapped[Decimal] - Decimal(19,4), default=initial_capital
|
|
currency: Mapped[str] - String(3), default="AUD"
|
|
is_active: Mapped[bool] - Boolean, default=True
|
|
|
|
# Relationships
|
|
user: Mapped["User"] - back_populates="portfolios"
|
|
|
|
# Constraints
|
|
__table_args__ = (
|
|
UniqueConstraint('user_id', 'name'),
|
|
)
|
|
```
