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; exposesExecuteAsync(IEventSource),AggregateAsync<T>(streamId), the presetSession, and the recordingOutbox.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 anAction<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.

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 release for hosts on the Orleans execution model. A durable timer now answers its tick while its handler runs, so a
long handler leaves no reminder error in the silo's log, and a timer that fails is logged by the framework with its
owner and purpose. A commit no longer constructs every registered projection to learn which store readers to wake. No
API change, no schema change and no migration.
### Changed
- **A commit no longer constructs every projection.** On the Orleans execution model, every command that committed
facts constructed each registered projection, with its dependencies, only to learn the names of the store readers to
wake. The names are now worked out once per silo, and the wait for a projection, the rebuild and the full replay's
checkpoint reset use the same list. A rebuild of a name that is not registered is refused before any reader is
paused, with the same message as before.
### Fixed
- **A durable timer answers its tick while its handler runs.** On the Orleans execution model, a durable timer's
reminder call stayed open until its handler returned, so a handler longer than the runtime's response timeout made
Orleans log `Could not deliver reminder tick` at Error for every tick it outlasted. The tick is now answered at once
and the handler runs in a call that carries no response timeout. The timer still fires once per due time, a tick
during its handler still does nothing, and a handler stopped with its silo still fires again on the next one.
- **A failing timer is logged.** A durable timer whose handler threw — or whose owner check or unregistration
failed — was visible only as Orleans' reminder error line. It is now logged as `117_137` `TimerFiringFailed` (Error)
with the owner, the purpose and the exception, and the timer fires again after its retry period as before.
