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
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.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.

### Added
- **New package `Stratara.Testing`** — test doubles and assertion helpers so consumers can
unit-test Stratara-based code without Postgres or RabbitMQ testcontainers. Reference it from
test projects only.
- `AggregateTestHarness<T>` + `Aggregate.Rehydrate<T>(...)` — given/when/then rehydration of an
aggregate from events using the same reflection-based `Apply(...)` dispatch as the production
aggregation service. It throws on an event with no matching `Apply` overload so a forgotten or
mistyped overload fails the test; opt back into the production-lenient skip with
`IgnoringUnmappedEvents()`.
- `InMemoryKeyStore` — an `IKeyStore` that mints random 256-bit DEKs per `KeyScope` and supports
rotation / revocation / scope-erasure without a master KEK or key file.
- `TestBlobEncryptor.CreateAesGcm()` — the real AES-GCM `ISecureBlobEncryptor` over an
`InMemoryKeyStore`, so blob round-trips exercise production encryption.
- `InMemoryMessageBus` — an `IMessageBus` with synchronous in-process dispatch and a `Published`
list for assertions.
- `TestSessionContext` / `TestSessionContextProvider` — preset Actor/Subject `SessionContext`
values and an `ISessionContextProvider` double.
- `TestTenants.Of("acme")` — stable, deterministic tenant/user ids from readable slugs.
`TestSessionContext` sets both correlation and causation ids so the context can drive
event-store writes.
- `TestEvent.Create(payload, ...)` — wrap an event payload in `IEvent<T>` with realistic
metadata; `ProjectionTester.HandleAsync(projection, event)` — invoke a projection's private
`HandleAsync` handler directly to unit-test it against mocked repositories.
- **New package `Stratara.Testing.EntityFrameworkCore`** — spins up the **real** event-sourcing
write stack (`IEventSource`, `IAggregationService`, snapshots, the EF Core write store) against a
shared in-memory SQLite database in one call, so tests exercise production code paths without
Postgres or Docker. Reference it from test projects only.
- `EventStoreTestHost.Create(...)` — owns the SQLite connection + service provider; exposes
`ExecuteAsync(IEventSource)`, `AggregateAsync<T>(streamId)`, the preset `Session`, and the
recording `Outbox`.
- `AddStrataraTestingEventStore<TWriteDbContext>(connection, tenantId)` — the lower-level DI
extension; `StrataraTestWriteDbContext` — a ready-made concrete write context;
`RecordingEventBundleOutboxDispatcher` — captures emitted bundles for assertions.
- The lockstep family grows from 22 to 24 packable packages.
