Description

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.
