Phase 3 Plan 2: Flattening Tests Summary

13 tests verifying ItineraryFlattener produces deterministic, sortOrder-based output with explicit ROADMAP success criteria coverage

Performance

• Duration: 15 min
• Started: 2026-01-18T21:59:19Z
• Completed: 2026-01-18T22:13:59Z
• Tasks: 2
• Tests added: 13

Accomplishments

• Created ItineraryFlattenerTests.swift with comprehensive test coverage
• 3 success criteria tests mapping directly to ROADMAP requirements
• 6 comprehensive coverage tests for edge cases
• 4 integration tests for realistic trip data configurations
• All tests pass, full test suite confirms no regressions

Task Commits

Each task was committed atomically:

1. Task 1: Create ItineraryFlattenerTests - 378e0ad (test)
2. Task 2: Add integration tests - 724b9f8 (test)

Files Created

• SportsTimeTests/Domain/ItineraryFlattenerTests.swift - 765 lines, 13 tests

Success Criteria Verification

The three ROADMAP success criteria now have explicit tests:

Success Criterion	Test Name
Negative sortOrder before games	success_negativeSortOrderAppearsBeforeGames
Deterministic flattening	success_sameStateProducesIdenticalOrder
Reorder preserves position	success_reorderPreservesNewOrder

Test Coverage

Success Criteria Tests (3)

• success_negativeSortOrderAppearsBeforeGames - Item with sortOrder -1.0 appears before noon game
• success_sameStateProducesIdenticalOrder - Repeated flatten produces identical row IDs
• success_reorderPreservesNewOrder - Changed sortOrder results in new order after reflatten

Comprehensive Coverage Tests (6)

• flatten_dayHeaderAlwaysFirst - Day header is structural anchor
• flatten_sortsByDayThenSortOrder - Items grouped by day, sorted within
• flatten_gamesGetSortOrderFromTime - 8pm game after item with sortOrder 500
• flatten_gamesGetSortOrderFromTime_earlyGame - 1pm game before item with sortOrder 1000
• flatten_emptyDayHasOnlyHeader - Rest day produces only header row
• flatten_multipleGamesOnSameDay - Multiple games in single games row

Integration Tests (4)

• flatten_travelWithNegativeSortOrderAppearsBeforeGames - Travel at -5.0 before games
• flatten_travelWithPositiveSortOrderAppearsAfterGames - Travel at 1500.0 after games
• flatten_mixedItemTypes - Complex day with exact order verification
• flatten_multiDayTrip - 3-day trip with different configurations per day

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None.

User Setup Required

None - no external service configuration required.

Phase 3 Complete

Phase 3 (Visual Flattening) is now complete:

• Plan 1: Created ItineraryFlattener pure utility
• Plan 2: Added comprehensive test coverage

Phase 4 (Drag-Drop) can now build on the verified, deterministic flattening behavior.
