## Description

<!-- SECTION:DESCRIPTION:BEGIN -->
_GitHub: created 2025-10-25 · updated 2026-02-07 · closed 2026-02-07_

Comprehensive test coverage analysis. Key gaps identified:

**Critical (High Priority):**
- 9 of 10 background workers untested (FetchArtistImage, FetchArtistInfo, RecordRefreshMusicBrainzData, RefreshCover, PopulateGenres, GenerateRecordEmbedding, PruneArtistInfo, PruneAssetCache, ExtractColors)
- Scrobble LiveView — user-facing feature with Last.fm integration
- LastFmController — OAuth authentication flow

**Moderate Priority:**
- Universal Search LiveView
- ArchiveController (backup download)
- HealthController

**Low Priority:**
- Online Store Templates LiveView
- Notes management
- Stats detail LiveViews (top albums/artists)
- Color extraction feature

**Well-tested areas:** Collection/Wishlist/Artist/Stats LiveViews, core context modules (Records, Collection, Wishlist, Artists, ScrobbleActivity, ScrobbleRules), external API clients (MusicBrainz, LastFm, Discogs), AssetController, CollectionController, SessionController, Auth plug.
