- 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.
Musify
Music streaming platform: upload your own tracks (or import them from YouTube),
process them asynchronously (audio transcoded to .m4a, thumbnails generated)
and stream them without the bytes ever going through the API.
backend/ .NET 10 — Domain / Application / Infrastructure / Api / Worker / StreamingGateway / Tests
web-player/ SvelteKit 2 + Svelte 5 + Tailwind 4 web client
deploy/ Docker Compose stacks — self-contained, no wrapper scripts
docs/ What each piece does and why (in Spanish)
dotnet test backend/Musify.slnx # backend/Tests/ — Docker running (Testcontainers: Postgres, SeaweedFS)
Run it
Development (Docker Desktop):
docker compose -f deploy/compose.yml -f deploy/compose.dev.yml up -d
Infrastructure plus stream-ticket keys, database migrations and Zitadel OIDC
provisioning — all as one-shot jobs baked into the compose file. Apps run from
the IDE by default; add --profile apps up -d --build as a second command to
run them in Docker instead.
Production, on a server with a domain:
cp deploy/.env.prod.example deploy/.env.prod # fill in the domain and secrets
docker compose --env-file deploy/.env.prod -f deploy/compose.yml -f deploy/compose.prod.yml up -d
docker compose --env-file deploy/.env.prod -f deploy/compose.yml -f deploy/compose.prod.yml --profile apps up -d --build
Idempotent — run the same commands again to deploy an update. See deploy/README.md for the details, the port map and the production prerequisites.
