Stratara.Testing

Test doubles and assertion helpers for applications built on the Stratara framework. Unit-test your event-sourced aggregates, encryption, messaging, and session-aware code without spinning up Postgres or RabbitMQ testcontainers.

Contents

  • AggregateTestHarness<T> / Aggregate.Rehydrate<T>(...) — given/when/then rehydration of an aggregate from events, using the same Apply(...) dispatch as production. Throws on an unmapped event so a forgotten overload fails the test (opt out with IgnoringUnmappedEvents()).
  • InMemoryKeyStore — an IKeyStore that mints random 256-bit DEKs per scope 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.
  • InMemoryTenantMembershipStore — an ITenantMembershipStore mirroring the EF store's contract semantics, including the membership-guarded active-tenant selection and the erasure sweeps.
  • InMemorySettingStore — an ISettingStore with exact-scope reads/writes, so the scoped-settings fallback chain can be exercised without a database.
  • TestTenants.Of("acme") — stable, deterministic tenant/user ids derived from readable slugs.
  • 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, so you can unit-test it against mocked repositories.

Example

var account = AggregateTestHarness<Account>
    .Given(new AccountOpened(id, "Ada", 100m))
    .And(new AmountWithdrawn(id, 30m))
    .Build();

Assert.Equal(70m, account.Balance);

Dependencies

  • Stratara.Abstractions, Stratara.Contracts, Stratara.Shared, Stratara.Security
  • Microsoft.Extensions.DependencyInjection

Reference it from your test projects only (<PackageReference Include="Stratara.Testing" />). It is not meant for production code paths — the InMemoryKeyStore and DummyKeyStore provide no durability or KEK custody.

Stratara.Testing.EntityFrameworkCore

Spin up the real Stratara event-sourcing write stack (EventSource, aggregation, snapshots, the EF Core write store) against a shared in-memory SQLite database in one call — production code paths, no Postgres, no Docker. Builds on Stratara.Testing's in-memory doubles.

### 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.
