# Phase 04 Plan 01: Queue Unit Tests Summary
|
|
|
|
**29 unit tests for queue core operations (SetQueue, Add, Insert, Move, Remove, Shuffle, Repeat), navigation logic (Next/Previous in all modes), and SaveState/RestoreState persistence roundtrip**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 3 min
|
|
- **Started:** 2026-03-03T21:57:38Z
|
|
- **Completed:** 2026-03-03T22:00:46Z
|
|
- **Tasks:** 2
|
|
- **Files modified:** 3
|
|
|
|
## Accomplishments
|
|
- 14 core operation tests: SetQueue (3 variants), AddTrack, InsertTracksAt (before/after current), MoveQueueTracks (forward/backward/current), RemoveTrack (normal/current), Clear, ToggleShuffle, CycleRepeat
|
|
- 9 navigation tests: nextIndex/previousIndex in RepeatOff/RepeatAll/RepeatOne modes, shuffle navigation, generateShuffleOrder property validation (all indices, no duplicates, current at [0])
|
|
- 6 persistence roundtrip tests: full state fidelity, empty/single/10-track edge cases, overwrite semantics, no-prior-save safety
|
|
- All 29 tests pass with `-race` flag
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Queue core operations and navigation tests** - `8d60dc0` (test)
|
|
2. **Task 2: Queue persistence round-trip tests** - `77cc993` (test)
|
|
|
|
## Files Created/Modified
|
|
- `backend/queue/queue_test.go` - Core operation tests + mock TrackLoader + setupTestQueue/seedAudioFiles helpers
|
|
- `backend/queue/navigation_test.go` - Navigation edge case tests + shuffle order property tests
|
|
- `backend/queue/persistence_test.go` - SaveState/RestoreState roundtrip fidelity tests
|
|
|
|
## Decisions Made
|
|
- Used internal tests (`package queue`) to access unexported fields (shuffleOrder, mu) — necessary for shuffle verification and roundtrip assertions
|
|
- Navigation tests bypass DB entirely using direct struct construction for fast, focused tests
|
|
- Roundtrip test asserts on shuffleOrder (JSON-serialized) to ensure Phase 7 refactoring won't silently lose shuffle state
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered
|
|
None
|
|
|
|
## User Setup Required
|
|
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
- Queue test safety net complete — ready for Phase 7 (PERF-01) incremental persistence refactoring
|
|
- Test helpers (mockTrackLoader, seedAudioFiles) available for reuse in Plan 04-02 (config/player tests)
|
|
- Ready for Plan 04-02 execution
