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.
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).
- 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.
Second pass on backend/Tests/, covering what Domain+Application (the first
pass) deliberately left out — the parts that talk to real infrastructure:
Musify.Infrastructure.Tests Database/migrations, StorageService,
StreamTicketService, AuditableEntityInterceptor,
PictureService, SingleFlightCache,
PlayListPresetSeeder.
Musify.Api.Tests Real HTTP endpoints via WebApplicationFactory
(routing, auth, ValidationFilter, ErrorOr->HTTP
mapping), plus isolated unit tests for
ErrorOrHttpExtensions, CurrentUser and the
FluentValidation validators.
Musify.StreamingGateway.Tests TicketValidator (RS256) and
TicketValidationMiddleware (path traversal,
prefix boundary, ticket extraction).
Musify.Worker gets no test project: its Program.cs is pure DI/host wiring
(Hangfire, MassTransit, jobs); the logic it runs lives in Musify.Infrastructure,
already covered there.
Per the user's direction, the parts that touch real infrastructure use
Testcontainers instead of fakes: a real Postgres (Testcontainers.PostgreSql)
for Infrastructure.Tests and Api.Tests, and — matching deploy/compose.yml
exactly (chrislusf/seaweedfs:latest, same startup command), not MinIO — a
real SeaweedFS container for StorageService. Api.Tests boots the actual
Musify.Api host against that Postgres (real routing/auth/validation) but
substitutes the services that talk over the network (storage, YouTube, the
message bus, stream-ticket signing) with NSubstitute fakes, and swaps the
JwtBearer scheme for a test-only header-based one (FakeAuthenticationHandler)
so tests don't need a reachable Zitadel. Application.Tests' approach — a real
DbContext (SQLite in-memory) rather than mocking IDatabase, since it exposes
DbSet<T> directly and handlers compose real LINQ queries against it — carries
over into Infrastructure.Tests/Api.Tests via real Postgres instead.
Testing against the real backend (not a fake) found two genuine production
bugs, both fixed here:
- StorageService.RemoveFolderAsync threw NullReferenceException against
SeaweedFS: its DeleteObjects response omits the <Error> list entirely when
nothing failed, which the AWS SDK deserializes as null rather than an empty
list (real AWS S3 always returns one). Now treats null as no errors.
- AuditableEntityInterceptor never bumped UpdatedAt on a normal update (load,
mutate a property, SaveChanges) — only on insert. SavingChanges(Async) fires
before EF's own automatic change detection for that save, so an entity
modified through a plain property setter still reported EntityState.Unchanged
inside the interceptor. Now calls ChangeTracker.DetectChanges() explicitly
first, which is the documented fix for exactly this interceptor pattern.
Also required to make the Api host testable: Program.cs now ends with `public
partial class Program;` (WebApplicationFactory<Program> needs the top-level-
statements Program class to be public — no behavior change), and
Directory.Packages.props gains Microsoft.AspNetCore.Mvc.Testing, Testcontainers
and Testcontainers.PostgreSql.
249 tests total across all five projects, all green: `dotnet test
backend/Musify.slnx` (needs Docker running for Infrastructure.Tests and
Api.Tests).
