This patch adds unit tests for the server-side optimal item selection
functionality.
t/db_dependent/Koha/Booking.t:
- Added subtest for _select_optimal_item() method (7 tests)
* Tests with no items (returns undef)
* Tests with single item (returns that item)
* Tests with multiple items (selects item with longest future availability)
* Tests optimal selection across items with different booking patterns
* Tests handling of cancelled bookings (ignored in selection)
* Tests iterator reset after selection
- Added subtest for _assign_item_for_booking() with itemtype filtering (6 tests)
* Tests booking without item_id or itemtype_id (selects any available)
* Tests booking with itemtype_id (filters by type)
* Tests optimal selection within filtered itemtype
* Tests exception when no items of specified type available
- Added integration test for full optimal selection workflow (5 tests)
* Creates 3 items with different future booking patterns
* Verifies items selected in optimal order (B→C→A)
* Demonstrates preservation of constrained resources
* Validates complete algorithm chain
* Tests booking failure when all items exhausted
t/db_dependent/api/v1/bookings.t:
- Added subtest for itemtype_id parameter validation (16 tests)
* Tests successful booking creation with itemtype_id
* Tests that item is automatically assigned
* Tests validation: cannot specify both item_id and itemtype_id
* Tests validation: must specify either item_id or itemtype_id
* Tests clash detection with itemtype-based bookings
- Fixed duplicate booking_id test to use different dates
* Prevents clash detection from masking duplicate ID constraint
- Updated test count from 3 to 8 subtests in Booking.t
- Updated test count to match actual assertions (16 not 18)
Test Coverage:
- Internal method testing: _select_optimal_item()
- Integration testing: _assign_item_for_booking()
- API endpoint testing: add() with itemtype_id
- End-to-end workflow validation
- Edge cases: empty sets, single items, ties, cancelled bookings
Test plan:
1. prove t/db_dependent/Koha/Booking.t
2. prove t/db_dependent/api/v1/bookings.t
3. Verify all tests pass
