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 patch for the shared identity store: single roles of a membership can now change without losing a concurrent
change, and a fresh store's first migration no longer logs a spurious error.

### Added

- **`ITenantMembershipStore.AddRolesAsync` and `RemoveRolesAsync`** give or take single roles of one membership,
 leaving its other roles and its status as they are, and return the membership afterwards (`null` where there is
 none — neither creates one). On the framework's stores two overlapping role changes to the same membership both
 take effect; a store that keeps losing to concurrent writers throws `InvalidOperationException` instead of dropping
 the change. No schema change. Both are default interface methods, so a store you implemented yourself keeps
 compiling and gets them as a read followed by a whole write — without protection against a concurrent writer.
 `TenantMembership.WithRolesAdded` and `WithRolesRemoved` compute the changed role set.

### Fixed

- **`MigrateStrataraIdentityStoreAsync()` no longer logs an `Error` on a fresh database.** The first migration of an
 empty identity store logged a failed read of its migration history table from
 `Microsoft.EntityFrameworkCore.Database.Command`, although the migration then succeeded. The database, the schema and
 the history table are now created before the migrations run, so a first start logs nothing at `Error` or above —
 also when several hosts start against an empty store at once.
