<objective>
Write comprehensive unit tests for the queue package covering core operations, navigation logic, and state persistence.
Purpose: Queue tests are the highest-priority safety net — Phase 7 (PERF-01) will change queue persistence from full table rewrite to incremental INSERT/DELETE. These tests must catch any data loss or index corruption during that refactoring.
Output: 3 test files with ~15-20 tests covering SetQueue, Next, Previous, shuffle, repeat modes, Add/Insert/Move/Remove, and full persistence round-trip.

<name>Task 1: Queue core operations and navigation tests</name>
<files>backend/queue/queue_test.go, backend/queue/navigation_test.go</files>
<action>
Create two test files for the queue package using internal tests (package queue, not queue_test).
**queue_test.go** — Core operation tests (~10-12 tests):
1. Define a `mockTrackLoader` struct satisfying `TrackLoader` interface at top of file. All methods are no-ops: `LoadFile` returns nil, `Play` returns nil, `IsPlaying` returns false, `CurrentPositionSeconds` returns (0, nil), `UnloadTrack` is empty. Add a `loadedFile string` field to track which file was loaded.
2. Define a `setupTestQueue(t *testing.T) (*Queue, *database.DB)` helper that:
- Calls `database.NewTestDB(t)` to get isolated DB
- Creates `NewQueue(slog.Default(), db)`
- Sets a `&mockTrackLoader{}` via `SetPlayer`
- Returns queue and db
3. Define a `seedAudioFiles(t *testing.T, db *database.DB, count int) []string` helper that:
- Inserts `count` audio_file rows with FK chain (1 shared artist_credit, 1 shared recording per file, audio_files with file_path `/test/trackN.mp3`)
- Uses `db.ExecContext()` for raw SQL inserts
- Returns the file paths as a string slice
- Uses `t.Helper()`
4. Write these test functions (all with t.Parallel()):
- `TestSetQueue_PopulatesTracks` — SetQueue with 5 file paths at startIndex 0, verify GetState returns correct track count and currentIndex
- `TestSetQueue_WithStartIndex` — SetQueue at startIndex 2, verify currentIndex is 2
- `TestSetQueue_WithShuffleStart` — SetQueue with shuffleStart=true, verify shuffleMode is true and shuffleOrder is populated
- `TestAddTrack_AppendsToQueue` — SetQueue with 3 tracks, AddTrack a 4th, verify 4 tracks total and the new track is last
- `TestInsertTracksAt_BeforeCurrentIndex` — SetQueue 5 tracks at index 2, InsertTracksAt index 1, verify currentIndex shifted by inserted count
- `TestInsertTracksAt_AfterCurrentIndex` — same but insert at index 3, verify currentIndex unchanged
- `TestMoveQueueTracks_ForwardMove` — SetQueue 5 tracks, move track from index 1 to index 3, verify order and currentIndex adjustment
- `TestMoveQueueTracks_BackwardMove` — move from index 3 to index 1, verify order
- `TestMoveQueueTracks_MoveCurrentTrack` — move the current track, verify currentIndex follows it
- `TestRemoveTrack_RemovesCorrectTrack` — SetQueue 5 tracks, remove at index 2, verify 4 tracks remain and correct track removed
- `TestRemoveTrack_RemoveCurrentTrack` — remove at currentIndex, verify index adjusts
- `TestClear_EmptiesQueue` — SetQueue, Clear, verify empty state
- `TestToggleShuffle_TogglesMode` — verify shuffle toggles on/off and shuffleOrder populates/clears
- `TestCycleRepeat_CyclesThroughModes` — verify off→all→one→off cycle
**navigation_test.go** — Navigation edge case tests (~6-8 tests):
Use direct field manipulation (same package) to set up queue state without DB:
- Create queue with `&Queue{logger: slog.Default()}`, set `tracks`, `currentIndex`, `shuffleMode`, `repeatMode`, `shuffleOrder` directly
Tests (all t.Parallel()):
- `TestNextIndex_NormalMode_AdvancesToNextTrack` — 5 tracks, index 2, repeatOff → returns 3
- `TestNextIndex_NormalMode_EndOfQueue_RepeatOff` — index at last track, repeatOff → returns -1
- `TestNextIndex_NormalMode_EndOfQueue_RepeatAll` — index at last track, repeatAll → returns 0 (wraps)
- `TestNextIndex_RepeatOne` — any index, repeatOne → returns same index
- `TestPreviousIndex_NormalMode_GoesBack` — index 3, repeatOff → returns 2
- `TestPreviousIndex_AtStart_RepeatOff` — index 0, repeatOff → returns -1
- `TestPreviousIndex_AtStart_RepeatAll` — index 0, repeatAll → returns last index
- `TestGenerateShuffleOrder_Properties` — table-driven test verifying: all indices present, no duplicates, current track at shuffleOrder[0], length matches tracks length. Test with 1, 5, and 20 tracks.
- `TestNextIndex_ShuffleMode` — set shuffleOrder, verify navigation follows shuffle order not track order
Use the established codebase test conventions: t.Parallel(), t.Helper() on helpers, t.Errorf with "got X, want Y" format, no assertion libraries.

<name>Task 2: Queue persistence round-trip tests</name>
<files>backend/queue/persistence_test.go</files>
<action>
Create persistence_test.go in the queue package (internal, package queue).
Reuse the `setupTestQueue` and `seedAudioFiles` helpers from queue_test.go (same package, accessible).
Write these test functions (all t.Parallel()):
- `TestSaveState_RestoreState_Roundtrip` — The critical safety net test:
1. Setup queue with DB, seed 5 audio files
2. SetQueue with 5 file paths at startIndex 2
3. CycleRepeat to "all"
4. ToggleShuffle
5. SaveState
6. Create a NEW Queue instance with same DB: `q2 := NewQueue(slog.Default(), db); q2.SetPlayer(&amp;mockTrackLoader{})`
7. RestoreState on q2
8. Verify ALL fields match: tracks length, each track's FilePath/Title/Artist, currentIndex, shuffleMode, repeatMode, shuffleOrder
- `TestSaveState_RestoreState_EmptyQueue` — SaveState with no tracks, RestoreState, verify empty state
- `TestSaveState_RestoreState_SingleTrack` — Verify edge case with 1 track
- `TestSaveState_RestoreState_PreservesTrackOrder` — SetQueue with 10 tracks, verify exact order after restore (not just count)
- `TestRestoreState_NoSavedState` — RestoreState on fresh DB with no prior SaveState, verify queue stays empty (no panic, no error)
- `TestSaveState_OverwritesPreviousState` — SaveState with 5 tracks, then SaveState with 3 different tracks, RestoreState should get the 3 tracks
These tests are the highest-priority safety net for Phase 7 (PERF-01). The roundtrip test verifies ALL queue state fields survive serialization, which is essential before changing persistence from full-table-rewrite to incremental.

# 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

<objective>
Write unit tests for the config package (including all sub-config validators) and player pure logic (volume conversion, state mapping).
Purpose: Config tests verify roundtrip fidelity and validation rules, which are essential before any config format changes. Player logic tests characterize the volume conversion math and state mapping as a safety net for any future player refactoring.
Output: 6 test files — 5 for config/sub-configs (~8-10 tests) and 1 for player (~5-6 tests).

Create 5 test files for config and all sub-config packages. All use internal test packages (same package name). Follow established conventions: t.Parallel(), table-driven subtests, stdlib testing only, no assertion libraries, t.Helper() on helpers.
**backend/theme/config_test.go** (package theme) — ~3 tests:
- `TestThemeConfig_Validate_ValidValues` — table-driven: valid hex colors ("#fff", "#ffd43b", "#000000") with valid shades ("darker", "dark", "light") all pass
- `TestThemeConfig_Validate_InvalidHexColor` — table-driven: invalid colors ("fff", "#gg0000", "#12345", "red", "") all return error containing "invalid hex color"
- `TestThemeConfig_Validate_InvalidBackgroundShade` — shade "neon" returns error containing "unknown background shade"
- `TestThemeConfig_ApplyDefaults` — verify zero-value Config gets DefaultAccentColor and DefaultBackgroundShade
**backend/tracklist/config_test.go** (package tracklist) — ~3 tests:
- `TestTrackListConfig_Validate_ValidColumns` — valid column IDs pass
- `TestTrackListConfig_Validate_UnknownColumnID` — unknown ID returns error containing "unknown track-list column ID"
- `TestTrackListConfig_Validate_DuplicateColumn` — duplicate ID returns error containing "duplicate column ID"
- `TestTrackListConfig_ApplyDefaults` — verify zero-value Config gets DefaultColumns
**backend/favorites/config_test.go** (package favorites) — ~2-3 tests:
- `TestFavoritesConfig_Validate_ValidIconStyles` — table-driven: "heart", "star" both pass
- `TestFavoritesConfig_Validate_InvalidIconStyle` — "diamond" returns error containing "unknown favorites icon style"
- `TestFavoritesConfig_ApplyDefaults` — verify zero-value gets DefaultIconStyle
**backend/library/config_test.go** (package library) — ~3-4 tests:
- `TestLibraryConfig_Validate_ValidDirectory` — use t.TempDir() as directory, all scan concurrency modes ("auto", "ssd", "hdd") pass
- `TestLibraryConfig_Validate_NonexistentDirectory` — "/nonexistent/path/xyz" returns error
- `TestLibraryConfig_Validate_InvalidScanConcurrency` — "turbo" returns error containing "unknown scan concurrency"
- `TestLibraryConfig_Validate_EmptyDirectory` — empty DirectoryPath with valid scan concurrency passes (no dir check when empty)
- `TestLibraryConfig_ApplyDefaults` — verify zero-value ScanConcurrency gets DefaultScanConcurrency
**backend/config/config_test.go** (package config) — ~3-4 tests:
- `TestConfig_LoadSave_Roundtrip` — The critical roundtrip test:
1. Create Config struct directly with `filePath` set to `filepath.Join(t.TempDir(), "config.toml")`
2. Set all sub-configs to non-default values: theme accent "#ff0000", shade "light", tracklist columns with 5 columns, favorites icon "star", library directory set to a second t.TempDir(), library scan concurrency "ssd", window 800x600
3. Call applyDefaults() then Save()
4. Create NEW Config struct with same filePath, call Load()
5. Verify ALL fields match the original values
Note: Set `logger` to `slog.Default()` on the Config struct for both instances.
- `TestConfig_Load_MissingFile` — Config with filePath pointing to nonexistent file. Load() should create the file with defaults (current behavior). Verify file exists after Load().
- `TestConfig_Validate_ComposesSubConfigErrors` — Config with invalid theme (bad hex) AND invalid tracklist (unknown column) returns an error. Verify both error messages are present (errors.Join behavior).
- `TestConfig_ApplyDefaults_NilSubConfigs` — Config with all nil sub-configs, call applyDefaults(), verify all sub-configs are non-nil with sensible defaults.
For the roundtrip test, import sub-config packages: theme, tracklist, favorites, library. Access unexported fields (filePath, logger) directly since this is an internal test (package config).

<files>backend/player/volume_test.go</files>
<action>
Create volume_test.go in the player package (internal, package player). Follow established conventions: t.Parallel(), table-driven subtests, stdlib testing only.
Write these test functions:
- `TestUserVolume_ToVolume` — table-driven with cases:
| UserVolume | Expected Volume |
|------------|-----------------|
| 0 (MinUserVol) | -5.0 (MinVol) |
| 100 (MaxUserVol) | 0.0 (MaxVol) |
| 50 (DefaultUserVol) | -2.5 (midpoint) |
| 25 | -3.75 |
| 75 | -1.25 |
For each: verify `uv.ToVolume()` matches expected within a tolerance of 0.001 (use math.Abs for float comparison).
- `TestVolume_ToUserVolume` — table-driven with inverse cases:
| Volume | Expected UserVolume |
|--------|---------------------|
| -5.0 (MinVol) | 0 (MinUserVol) |
| 0.0 (MaxVol) | 100 (MaxUserVol) |
| -2.5 | 50 |
| -3.75 | 25 |
| -1.25 | 75 |
For each: verify `v.ToUserVolume()` matches expected exactly (int comparison).
- `TestUserVolume_ToVolume_OutOfRange` — table-driven: values outside [0,100] like -1, 101, 200, -50. Verify ToVolume() returns zero-value Volume (0.0) per current implementation (the `if` guard fails, returns uninitialized `newVol`).
- `TestVolume_ToUserVolume_OutOfRange` — values outside [-5,0] like -6.0, 1.0, -10.0. Verify ToUserVolume() returns zero-value UserVolume (0) per current implementation.
- `TestUserVolume_ToVolume_Roundtrip` — for every UserVolume from 0 to 100, convert to Volume and back. Verify roundtrip matches original value. This is the characterization test — if the math changes, this breaks.
- `TestClampVolume` — table-driven:
| Input | Expected |
|-------|----------|
| -10 | 0 (MinUserVol) |
| 0 | 0 |
| 50 | 50 |
| 100 | 100 |
| 150 | 100 (MaxUserVol) |
- `TestStateToMediaControls` — table-driven:
| State | Expected PlaybackState |
|-------|------------------------|
| Playing | mediacontrols.StatePlaying (1) |
| Paused | mediacontrols.StatePaused (2) |
| Stopped | mediacontrols.StateStopped (0) |
| State("unknown") | mediacontrols.StateStopped (0) — default case |
Import "yellowjacket/backend/mediacontrols" for the PlaybackState constants. Use `math` for float comparison tolerance.

# Phase 04 Plan 02: Config & Player Tests Summary
**Unit tests for config load/save roundtrip, all sub-config validators (theme/tracklist/favorites/library), and player volume conversion + state mapping — 27 test cases across 6 packages, all passing with -race**
## Performance
- **Duration:** 4 min
- **Started:** 2026-03-03T21:57:19Z
- **Completed:** 2026-03-03T22:02:12Z
- **Tasks:** 2
- **Files modified:** 6
## Accomplishments
- Config load/save roundtrip test verifies all fields survive TOML serialization
- All 4 sub-config validators (theme, tracklist, favorites, library) tested for valid values, invalid values, and defaults
- Player volume conversion tested at all boundaries with full 0-100 roundtrip characterization
- stateToMediaControls mapping verified for all states including unknown fallback
- All tests pass with `-race` flag
## Task Commits
Each task was committed atomically:
1. **Task 1: Config and sub-config validation tests** - `f9b2ad9` (test)
2. **Task 2: Player volume and state mapping tests** - `294b629` (test)
## Files Created/Modified
- `backend/config/config_test.go` - Load/Save roundtrip, missing file, composed errors, nil defaults (227 lines)
- `backend/theme/config_test.go` - Hex color regex + background shade enum validation (83 lines)
- `backend/tracklist/config_test.go` - Column ID recognition + duplicate detection (73 lines)
- `backend/favorites/config_test.go` - Icon style enum validation (49 lines)
- `backend/library/config_test.go` - Directory existence + scan concurrency mode validation (83 lines)
- `backend/player/volume_test.go` - Volume conversion, clamp, state mapping (198 lines)
## Decisions Made
- **Roundtrip tolerance:** The `ToVolume`/`ToUserVolume` conversion uses `int()` truncation (not `math.Round`), so some values lose 1 unit in the roundtrip. The characterization test documents this with a ±1 tolerance, while verifying boundary values (0, 50, 100) are exact.
- **Empty AccentColor not invalid:** `Validate()` calls `ApplyDefaults()` first, which fills empty accent color with `#ffd43b`, so empty string is handled gracefully rather than being an error case.
## Deviations from Plan
### Auto-fixed Issues
**1. [Rule 1 - Bug] Removed empty-string hex color from invalid test cases**
- **Found during:** Task 1 (theme validation tests)
- **Issue:** Plan listed empty string as invalid hex color, but `Validate()` calls `ApplyDefaults()` first which fills in the default color
- **Fix:** Removed empty string from invalid test cases — it's valid behavior by design
- **Files modified:** backend/theme/config_test.go
- **Verification:** All theme tests pass
- **Committed in:** f9b2ad9 (Task 1 commit)
**2. [Rule 1 - Bug] Changed roundtrip test from exact to ±1 tolerance**
- **Found during:** Task 2 (volume roundtrip test)
- **Issue:** Plan specified exact roundtrip match for all 0-100 values, but `ToUserVolume()` uses `int()` truncation causing up to 1 unit drift
- **Fix:** Changed to ±1 tolerance with separate exact checks for boundary values (0, 50, 100)
- **Files modified:** backend/player/volume_test.go
- **Verification:** All player tests pass with -race
- **Committed in:** 294b629 (Task 2 commit)
---
**Total deviations:** 2 auto-fixed (2 bugs — plan assumptions didn't match actual code behavior)
**Impact on plan:** Both fixes accurately characterize existing behavior rather than imposing incorrect expectations. No scope creep.
## Issues Encountered
None
## User Setup Required
None - no external service configuration required.
## Next Phase Readiness
- Config and player pure logic fully characterized with tests
- Ready for remaining Phase 4 plans (queue tests) or Phase 5 (database query tests)
## Self-Check: PASSED
All 6 created files verified on disk. Both commits (f9b2ad9, 294b629) verified in git log.

# Phase 4: Queue, Config & Player Tests - Context
**Gathered:** 2026-03-03
**Status:** Ready for planning
<domain>
## Phase Boundary
Write unit tests for three packages: queue operations (SetQueue, Next, Previous, shuffle, repeat, persistence), config roundtrip (load/save, validation, defaults), and player pure logic (volume conversion, state mapping). These tests characterize current behavior and serve as a safety net for Phase 6-7 refactoring. No production code changes except adding test files.
</domain>
<decisions>
## Implementation Decisions
### Test fixture strategy
- Per-test inline setup for queue — each test creates its own audio_file FK rows with minimal fields. Verbose but self-contained; a test failure tells you everything.
- t.TempDir() for config filesystem tests — real filesystem via Go's test temp dirs, auto-cleaned, tests actual TOML read/write.
- Simple mock TrackLoader struct defined locally in queue_test.go — only queue tests need it, keep it local.
- Player tests are pure logic only — no NewTestDB, no persistence round-trips. Volume conversion, clamp, state mapping only. Player persistence deferred to integration tests.
### Player logic extraction
- Test existing pure logic in place — volume.go (UserVolume, Volume, clampVolume) is already cleanly separated. Write volume_test.go against it. No extraction from player.go.
- Include stateToMediaControls() — it's pure and trivial but documents the state mapping. Characterization value.
- Format detection tested in metadata package, not player — the code lives in metadata/decoder.go, tests belong there (decoder_test.go or similar).
- Do NOT extract anything new from player.go — lock-sensitive code must not be touched. Test what's already pure.
### Coverage depth vs breadth
- Queue: edge cases first — empty queue, single track, last track, first track, remove current track. These are where bugs hide and refactoring breaks.
- Queue: dedicated move test cases — move forward, move backward, move current track, move to boundaries, move multiple tracks. MoveQueueTracks has the most complex index arithmetic.
- Queue: test InsertTracksAt index shifts — insert before/at/after current index, verify currentIndex adjusts correctly. Common off-by-one bug source.
- Queue: verify generateShuffleOrder() properties — all indices present, current track at index 0, no duplicates. Property-based validation.
- Queue: full persistence round-trip — SaveState → new Queue → RestoreState → verify all fields match (shuffle order, repeat mode, current index, track list). Critical for Phase 7 optimization safety.
- Config: test both sub-config validators independently AND the composed Config.Validate(). Pinpoints failures to specific validators.
- Config: include library.Config.Validate() path with t.TempDir() — test both valid directory (real temp dir) and invalid directory (nonexistent path).
- Player: 5-6 tests is sufficient — volume roundtrip, boundary values, clamp, state mapping. Quality over quantity.
### Test organization
- Internal test packages (package queue, package config, package player) — queue tests need access to unexported fields (shuffleOrder, currentIndex, tracks) for setup and assertions.
- Mirror source file names — navigation_test.go tests navigation.go, persistence_test.go tests persistence.go, queue_test.go tests queue.go. Easy to find tests for any function.
- Sub-config tests in their respective packages — theme/config_test.go, tracklist/config_test.go, favorites/config_test.go, library/config_test.go. Config package tests the composed Config.
- t.Parallel() everywhere — NewTestDB gives isolated DB instances, pure logic tests have no shared state. Matches existing coverart/metadata convention.
### Claude's Discretion
- Exact test case names and table-driven subtest structure
- How to organize table-driven tests vs individual test functions (per complexity)
- Specific assertion messages and error formatting
- Whether to use subtests within a single Test function or separate Test functions per behavior
</decisions>
<specifics>
## Specific Ideas
- Queue persistence round-trip is the highest-priority safety net — Phase 7 (PERF-01) will change queue persistence from full table rewrite to incremental INSERT/DELETE. These tests must catch any data loss.
- Mock TrackLoader should be minimal — just enough to satisfy the interface. LoadFile/Play/UnloadTrack can be no-ops, IsPlaying returns false, CurrentPositionSeconds returns 0.
- Queue tests need to insert audio_file rows before queue_tracks (FK constraint). Also need file_type rows since audio_files FKs to file_types.
- Player's existing player_test.go is an integration test guarded by YELLOWJACKET_INTEGRATION env var — new unit tests are separate and should always run.
- Existing test conventions: table-driven subtests with t.Run(), t.Parallel(), standard library testing only (no testify), no assertion libraries.
