Проблема:
- Поле OrderStatus.color имеет max_length=7 (для hex типа #FF5733)
- В тестах использовались названия: 'secondary', 'warning', 'success' (9 символов)
- PostgreSQL выдавал ошибку: value too long for type character varying(7)
Решение:
- Заменены названия цветов на hex коды:
* 'secondary' → '#9E9E9E' (серый)
* 'warning' → '#FF9800' (оранжевый)
* 'success' → '#4CAF50' (зелёный)
* 'danger' → '#F44336' (красный)
* 'info' → '#17A2B8' (голубой)
Tests cover:
1. Multiple status transitions (draft->completed->cancelled->completed)
2. Cancellation from draft (reservation release)
3. Un-cancellation to pending (reservation restore)
4. Creating order with intermediate status
5. Rollback from completed to draft
Each test verifies:
- Stock state (available, reserved, free)
- Reservation status transitions
- Sale creation/deletion without duplicates
- StockBatch quantity changes
