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
- **Event upcasting (`IEventUpcaster`).** Persisted events can now be transformed from an older
on-disk schema into the shape the current event record expects, applied on read before the payload
is deserialized. Register upcasters with `AddEventUpcaster<TUpcaster>()`; each implements
`IEventUpcaster` (`SourceEventTypeName` / `TargetEventTypeName` plus `JsonNode Upcast(JsonNode)`) and
they chain across successive schema versions (v1→v2→v3), including event-type renames — the source
type no longer needs to exist in the assembly. Matching ignores the assembly `Version` segment, and
a cyclic or duplicate-source chain is rejected. Hosts that register no upcasters are unaffected
(transparent pass-through). Snapshots are not upcasted — change an aggregate's shape and rebuild its
snapshots.
### Changed
- **Copyright holder corrected to the full legal name "Norbert Heinz Rosenwinkel"** in the `LICENSE`
file and in the `Authors` / `Copyright` package metadata. No code or licensing-terms change — the
license remains MIT.
