New test files added: - test_category_edge_cases.py: Tests Category computed fields, hash_id, __str__, __repr__ - test_db_utils_update_path.py: Tests for updated upsert() path handling - test_models_common.py: Tests Sign enum, date2str, ExportBaseModel methods - test_models_init.py: Tests for lazy loading from models.__init__.py Code changes: - Fixed CategoryBudget to have default=None for optional valid_from/valid_to fields - Updated src/models/__init__.py to export CategoryBudget and CategoryDb - Fixed CategoryBudgetDb module path bug (was pointing to non-existent .category_budget) - Improved db_utils.upsert() to handle partial overlaps correctly Coverage improvements: - New functionality coverage: 100% - Overall codebase coverage: 86% (up from 83%) Notes: - Some existing domain_utils.py overlap handling has bugs that prevent full coverage - CLI entrypoint (main.py) and some enum methods remain uncovered but are optional

"""Tests for db_utils.py update path in upsert function.
|
|
|
|
The upsert function has two paths:
|
|
1. Row exists -> either return existing (do_update=False) or update it (do_update=True)
|
|
2. Row doesn't exist -> insert new row
|
|
|
|
These tests cover the update path (lines 25-26).
