Stratara.Testing.EntityFrameworkCore

Derived. The behaviour described here is specified under openspec/specs/. Those specifications are the source; this page explains and illustrates them.

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

Contents

  • 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. The overload that takes a connection string opens a connection per context to a shared-cache in-memory database — for a store used from several threads, such as a silo's — and applies an Action<DbContextOptionsBuilder> after the provider, for an interceptor.
  • 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.

Dependencies

  • Stratara.Testing, Stratara.Infrastructure, Stratara.EventSourcing.EntityFrameworkCore, Stratara.Shared, Stratara.Abstractions, Stratara.Contracts

Stratara.Testing.Orleans

Run the Stratara Orleans execution model in a test's own process — one silo with in-memory reminders and grain directory, the real write stack, commit-order reader and checkpoint store on in-memory SQLite, and every period shortened to seconds. Register handlers, projections, sagas and timers with the production calls; no cluster, broker or database server. Builds on Stratara.Testing.EntityFrameworkCore.

A host on the Orleans execution model can now wait until a projection has applied what it committed, instead of
reading its read model and hoping the projection is through. Additive; no schema change and no migration.

### Added

- **`IProjectionProgress`** (`Stratara.Abstractions`), registered by `AddStrataraProjectionGrains()`.
 `MarkAsync()` returns a `StoreMark` that covers every entry committed at the time of the call, in every partition
 — on PostgreSQL also an entry that committed while another write was still open. `WaitAsync(projection, mark,
 timeout)`, with the projection named by its type or its framework name, answers with a `ProjectionWaitResult`:
 `Reached` only once the projection has applied every entry the mark covers; otherwise, at the limit, `Stalled`,
 `Suspended` or `TimedOut` with the partitions behind; `MarkNotApplicable` at once for a mark taken under another
 reader or partition count. A rebuild or a full replay during a wait is waited through; an unknown projection is
 refused. See *Read your own write* in the projection guide.
- **`ICommittedPositionReader.CommittedHeadAsync`**, the highest position the store shows as committed. The default
 answers `HeadAsync`; the native PostgreSQL reader answers it without the horizon its head is held back to. A
 reader of your own that holds its head back overrides it.

### Upgrade notes

- Adopt the wait once every silo runs this release: a silo of an earlier version does not answer it, and a wait
 whose partition lives there fails with the grain call's error.
