Drops the YouTube-backed second catalog source entirely: the
Local/External split on Track/Album collapses into single concrete
entities, Artist/TrackArtist/ExternalTrack/ExternalAlbum and the
YouTube service/download pipeline (yt-dlp, MassTransit consumer,
routing slip) are deleted, and mixes now source discovery only from
local listening history. Includes the RemoveYouTubeIntegration EF
Core migration and matching Worker/deploy/compose cleanup (no more
yt-dlp/python/deno in the Worker image, no thumbnail-cache/YtDlp
config sections).
Albums previously had no cover concept at all: no picture upload
flow, no GET /albums/{id}/cover, and AlbumApplicationResponse's
image-key fields were plumbed but never populated. Description,
Pictures and TrackCount already lived on the shared Album base entity
for both local and external albums, so unifying the cover story only
required building the missing local-album picture pipeline.
Backend, cloning PlayList's existing async picture-processing
architecture exactly (MassTransit routing slip + saga), but making
the picture mandatory instead of optional (matching Track's pattern):
- AlbumPictures moves from all-nullable to required fields.
- New AlbumConfiguration (routes/sizes), deliberately without
PlayList's preset-picture fallback since a picture is now required
up front.
- CreateAlbum now takes a mandatory PictureIntentId, validates and
consumes the upload intent, and kicks off the same
copy-to-final -> resize -> upload -> update-entity routing slip
PlayLists use, via a new AlbumProcessingState saga that marks the
album Failed on a picture-processing failure.
- UpdateAlbum takes an optional NewPictureIntentId to replace the
cover later.
- New GET /albums/{id}/cover and POST /albums/upload-picture
endpoints, mirroring the playlist ones.
- New EF migration for the AlbumProcessingState saga table.
Frontend:
- AlbumForm gains a cover dropzone, required on create and optional
on edit (via ImageDropzone's new `required` prop), uploaded through
the same presigned-upload helper playlists use.
- New /api/albums/{id}/cover proxy route.
- PlaylistArt gains a generic coverUrl prop so AlbumHeader and the
album list/detail cards render the real uploaded cover instead of
only the track mosaic fallback.
Delete-time picture cleanup for albums is intentionally left as a
follow-up, matching the existing gap in playlist deletion.
Removes the last YouTube-specific routes (/youtube/*) and merges them
into the general track/album/playlist endpoints, keyed by a `source`
string validated against TrackSource. This mirrors the earlier track
search merge for albums and playlist-track additions:
- GetAlbums now merges local albums with live YouTube Music search
results, paginated via a youtubeContinuationToken, deduped against
already-materialized ExternalAlbum rows.
- New GET /albums/external/{source}/{externalId} and
GET /tracks/external/{source}/{externalId}/stream replace the
YouTube-only equivalents.
- POST /playlists/{id}/tracks replaces the separate
.../youtube-tracks endpoint, accepting an optional Source/ExternalId
pair alongside TrackId.
- AlbumSearchItemResponse/AlbumsSearchResponse follow the same
discriminated-union + trailing-HasNextPage-field pattern already
used for track search, so HasNextPage stays a required field in the
generated OpenAPI schema.
- Frontend routes renamed accordingly (/albums/youtube/[albumId] ->
/albums/external/[source]/[externalId], etc.) with a single
/api/thumbnail proxy replacing /api/youtube/thumbnail.
Musify.Api.Endpoints.YouTubeEndpoints and the standalone
SearchYouTubeAlbums query are removed as a result.
Converts all 73 test source files from file-scoped (namespace X;) to
block-scoped (namespace X { ... }) declarations, re-indenting their
contents accordingly. Matches the existing convention already used in
several production files (e.g. Musify.Infrastructure.Configuration,
Musify.Application.Contracts).
Mechanical change only, done with a script, verified with a full
rebuild (0 warnings, 0 errors) and test run (257/257 passing).
- Directory.Packages.props: xunit 2.9.3 -> xunit.v3 4.0.0, bump
xunit.runner.visualstudio to the matching 4.0.0
- All 5 test csproj: xunit -> xunit.v3 package reference, add
<OutputType>Exe</OutputType> (v3 test projects are standalone
executables)
- backend/global.json: opt dotnet test into the new MTP-native mode
(.NET 10 SDK removed the old VSTest bridge for MTP-based test
projects like xunit v3)
- IAsyncLifetime implementations (HandlerTestBase, ApiTestFixture,
InfrastructureTestFixture, StorageServiceTests): v3's IAsyncLifetime
now IS IAsyncDisposable, so InitializeAsync/DisposeAsync return
ValueTask instead of Task. ApiTestFixture specifically now overrides
WebApplicationFactory.DisposeAsync instead of implementing
IAsyncLifetime.DisposeAsync explicitly, since v3 collapses both to
the same single DisposeAsync slot
- Replaced CancellationToken.None with TestContext.Current.CancellationToken
across the suite (a v3-only API) and added it to every call that
was silently omitting a CancellationToken argument, per the new
xUnit1051 analyzer warnings that came with the v3 package
Verified: dotnet build (0 warnings, 0 errors) and dotnet test, 250/250
passing under the new MTP runner.
- StorageServiceTests: replace out-param + manual dispose with IAsyncLifetime
- PictureServiceTests: Assert.True bound checks -> Assert.InRange
- CreateAlbumCommandHandlerTests: assert the specific NotFound error type
instead of just IsError, matching what the test name promises
- CreateAlbumRequestValidatorTests: replace a boundary Theory that computed
its expected result inline with explicit Facts against the real
AlbumReleaseYear constants
- Remove unused using directives across a handful of production and test
files found during the review
Full suite verified green: 250/250 tests passing, 0 build warnings.
Two xUnit projects, wired into Musify.slnx under a /Tests/ folder that
mirrors Core/ and Hosts/:
Musify.Domain.Tests Value-object logic (TrackAudio/TrackPictures'
IsProcessed/IsFailed/IsInProgress). Entities are
otherwise anemic EF models with no behavior to
test.
Musify.Application.Tests All ~45 Application handlers and services
(Albums, Tracks, PlayLists, Users, Mixes,
YouTube, plus TrackStreamIssuer,
UploadIntentValidator, YouTubeTrackProvisioner).
IDatabase exposes DbSet<T> directly, so handlers compose real LINQ queries
against it — that can't be expressed with a mock (no IQueryable provider
behind one). TestSupport/TestDatabase.cs is instead a real DbContext on a
private SQLite in-memory connection per test (fresh per test since xUnit
instantiates the test class per test method): fast, no external dependency,
and — unlike EF Core's InMemory provider — SQLite enforces real foreign keys
and supports transactions, which two handlers need. External dependencies
(IStorageService, IEventBus, IYouTubeMusicService, ...) are substituted with
NSubstitute.
TestSupport/TestEntities.cs and TestConfigurations.cs build fully-populated
domain entities and configuration POCOs with sensible defaults for every
required member, so no test method needs to fill in properties it doesn't
care about, and no builder ever hands back null.
Also, needed to make the Application layer itself testable without a real
Postgres or user-secrets:
- DatabaseDesignTimeFactory now falls back to the Database__ConnectionString
env var, and DesignSettings.json is optional — unblocks the `migrate`
one-shot container from deploy/compose.yml, which hit the same gap.
- Directory.Packages.props: xunit, xunit.runner.visualstudio, NSubstitute,
Microsoft.EntityFrameworkCore.Sqlite (pinned to the same 10.0.8 as the rest
of EF Core), Microsoft.NET.Test.Sdk, coverlet.collector. Also pins
SQLitePCLRaw.bundle_e_sqlite3 to 2.1.13 — EFCore.Sqlite 10.0.8 pulls 2.1.11
transitively, which has a known high-severity advisory (GHSA-2m69-gcr7-jv3q).
- backend/.dockerignore excludes Tests/: no application Dockerfile needs it
in its build context.
162 tests, all green: `dotnet test backend/Musify.slnx`.
