Stratara.Testing.EntityFrameworkCore

Spin up the real Stratara event-sourcing write stack — IEventSource, IAggregationService, snapshots, and the EF Core write store — against a shared in-memory SQLite database, in one call. You exercise production code paths (real serialization, real version tracking, real unique constraints) without Postgres or Docker.

Builds on Stratara.Testing: the cross-cutting dependencies are wired with its in-memory doubles (InMemoryKeyStore, TestSessionContextProvider).

Why not a hand-rolled in-memory `IEventSource`?

Because a bespoke fake would drift from production (subject resolution, concurrency detection, outbox dispatch, snapshots). This package runs the genuine EventSource on SQLite instead, so your tests verify the real behavior.

Example

await using var host = EventStoreTestHost.Create(s =>
    s.AddAggregatesFromAssemblyContaining<Account>());

await host.ExecuteAsync(async events =>
{
    await events.CreateAsync<Account>(id, new AccountOpened(id, tenantId, "Ada", 100m));
    await events.AppendAsync<Account>(id, new AmountWithdrawn(30m));
    await events.SaveChangesAsync();
});

var account = await host.AggregateAsync<Account>(id);
Assert.Equal(70m, account!.Balance);
Assert.Single(host.Outbox.Bundles);   // the SaveChanges emitted one bundle

EventStoreTestHost — owns a shared open SQLite connection + a configured service provider; exposes ExecuteAsync(IEventSource), AggregateAsync<T>(streamId), the preset Session, and the recording Outbox. IAsyncDisposable.
AddStrataraTestingEventStore<TWriteDbContext>(connection, tenantId) — the lower-level DI extension if you compose the provider yourself.
StrataraTestWriteDbContext — a ready-made concrete write context (no subclass boilerplate).
RecordingEventBundleOutboxDispatcher — captures emitted bundles for assertions.

Notes

The SQLite connection is :memory: and shared across every DbContext the unit of work mints — it must stay open for the host's lifetime (the host manages this; dispose it when done).
Register your aggregates (AddAggregatesFromAssemblyContaining<T>()) so event payload types deserialize on rehydration.

### Fixed

- **Snapshot loads are now scoped to the aggregate type.** The snapshot read previously filtered
only by stream id, so when two aggregate types shared a stream id, rehydrating one type could
pick up the other type's (higher-versioned) snapshot and deserialize it into the requested type —
silently returning an aggregate with default/empty fields. Snapshot reads now match the aggregate
type (version-independently, so an assembly rev-bump does not invalidate existing snapshots), and
snapshot writes are grouped per `(stream, aggregate type)` so a stream carrying more than one type
snapshots each type independently. A snapshot of type X may now only ever rehydrate type X.

### Changed

- **`ISnapshotRepository` gained type-scoped read overloads.** `GetAsync(streamId,
aggregateTypeName, toVersion, ct)` and `GetLatestVersionOrDefaultAsync(streamId,
aggregateTypeName, ct)` are the correct lookups; the previous type-less overloads are now
`[Obsolete]` because they can return a foreign aggregate type's snapshot on a shared stream.
Custom `ISnapshotRepository` implementers should add the new overloads.
