"""Tests for tradingagents/portfolio/models.py.

|
Tests the four dataclass models: Portfolio, Holding, Trade, PortfolioSnapshot.
|
|
|
|
Coverage targets:
|
|
- to_dict() / from_dict() round-trips
|
|
- enrich() computed-field logic
|
|
- Edge cases (zero cost basis, zero portfolio value)
|
|
|

Run::
