"""Tests for BE-CAL-005: Plan virtual-slot identification & materialization. Covers: - Virtual slot ID generation and parsing - Plan-date matching logic (on_day, on_week, on_month combinations) - Virtual slot generation (skipping already-materialized dates) - Materialization (virtual → real TimeSlot) - Detach (edit/cancel clears plan_id) - Bulk materialization for a date """ import pytest from datetime import date, time from tests.conftest import TestingSessionLocal from app.models.calendar import ( DayOfWeek, EventType, MonthOfYear, SchedulePlan, SlotStatus, SlotType, TimeSlot, ) from app.services.plan_slot import ( detach_slot_from_plan, get_virtual_slots_for_date, make_virtual_slot_id, materialize_all_for_date, materialize_from_virtual_id, materialize_slot, parse_virtual_slot_id, plan_matches_date, _week_of_month, ) #
