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`.
Single docker-compose stack for local development (Postgres, Zitadel,
RabbitMQ, SeaweedFS + bucket init, Jaeger) plus an optional overlay to run
the .NET apps in Docker. up.ps1 orchestrates the full bootstrap: stack up,
stream-ticket keys, EF Core migrations and Zitadel provisioning.
- Zitadel is provisioned automatically (service-account PAT -> project +
OIDC app with JWT access token); the generated ClientId is wired into
Musify.Api user-secrets and .env. No manual console steps.
- ZITADEL_EXTERNAL_DOMAIN=host.docker.internal so token validation works
both with local apps and full-docker.
- App Dockerfiles copy AppSettings*.json to lowercase so config loads on
case-sensitive Linux; Worker image ships ffmpeg.
- Scripts split by responsibility (common/stream-keys/migrate/provision);
apps overlay de-duped via YAML anchors.
- Remove the superseded standalone seaweedfs compose; point docs/development
at the unified stack.
