Stratara.Testing
Derived. The behaviour described here is specified under
openspec/specs/. Those specifications are the source; this page explains and illustrates them.
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 sameApply(...)dispatch as production. Throws on an unmapped event so a forgotten overload fails the test (opt out withIgnoringUnmappedEvents()).InMemoryKeyStore— anIKeyStorethat 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-GCMISecureBlobEncryptorover anInMemoryKeyStore, so blob round-trips exercise production encryption.InMemoryMessageBus— anIMessageBuswith synchronous in-process dispatch and aPublishedlist for assertions.TestSessionContext/TestSessionContextProvider— preset Actor/SubjectSessionContextvalues and anISessionContextProviderdouble.InMemoryTenantMembershipStore— anITenantMembershipStoremirroring the EF store's contract semantics, including the membership-guarded active-tenant selection and the erasure sweeps.InMemorySettingStore— anISettingStorewith exact-scope reads/writes, so the scoped-settings fallback chain can be exercised without a database.InMemoryApiKeyStore— anIApiKeyStoremirroring the EF store's contract semantics: issuance, idempotent import of a caller-supplied key, fail-closed validation, revocation, erasure sweeps, and machine keys materialized into a membership store you can share and inspect.TestTenants.Of("acme")— stable, deterministic tenant/user ids derived from readable slugs.TestEvent.Create(payload, ...)— wrap an event payload inIEvent<T>with realistic metadata.ProjectionTester.HandleAsync(projection, event)— invoke a projection's (private)HandleAsynchandler 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);

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. |

Correctness fixes for the Orleans execution model ahead of production use. Recorded commands can no longer
reach a bus drain, a durable timer fires once however long its handler runs, and heavy commands are
specified as the exception to the one-writer-per-aggregate promise they always were. The execution-model
reset removes only the host's own checkpoints, and three store-level fixes land for the partition
counter, its backfill and a checkpoint's first write. No schema change; **stop every bus outbox worker
before upgrading hosts that record commands through the execution model**, and register
`AddStrataraIntentStore` on the silos that run the drain.
### Changed
- **Orleans: the execution-model reset removes only the checkpoints of the host's own projections and
sagas.** It removed every checkpoint in the read store, so a reset in one deployment made another
deployment sharing the read store rebuild its projections unasked. The reset now removes the
checkpoints of the projections and sagas registered in the composition it is resolved from, and the
report counts only those. A checkpoint of a projection the host no longer registers stays; nothing
reads it. Resolve the reset from the host's own composition — one that registers no store reader
removes no checkpoint.
- **The documentation states when a read store can be shared.** Checkpoints are keyed by consumer, not
by deployment: deployments sharing a read store need distinct projection names, and at most one of
them runs `AddStrataraSagaGrains`.
- **Orleans: heavy commands are specified as running outside their aggregate's turn and order.** They
always ran in their own bounded pool beside the aggregate's other commands; the specification promised
otherwise. Their hand-over no longer holds the per-aggregate send order either: a command dispatched after
a heavy command for the same aggregate no longer waits for it, and two due heavy commands on one aggregate
no longer hold up the drain's resume pass. Where a heavy command and another command on the same aggregate
both append, the store's version check refuses the later one, which is resumed like any failing command.
- **Orleans: a recorded command is stored under a kind of its own.** No bus outbox drain reads it any more.
Commands recorded under 4.1.0 are still resumed; stop every bus outbox worker before upgrading hosts that
record commands.
### Fixed
- **Orleans: the outbox drain no longer publishes recorded commands to the bus.** It chose between resuming
recorded commands and publishing stored commands by whether the execution model's dispatcher was
registered on its own silo, and the migration guide registers the dispatcher on the API host and the drain
on the silos. Such a silo handed every recorded command — kept ones included — to the bus: commands ran
twice, kept commands came back, the attempt bound did not hold. The drain now resumes recorded commands
wherever an intent store is registered and warns (`117_111`) where recorded commands exist but none is.
Register `AddStrataraIntentStore` on the silos that run the drain.
- **Orleans: a durable timer fires once however long its handler runs.** A handler that outlasted the
reminder call's response timeout was started again by the next tick. A tick that arrives while the same
timer's handler runs now does nothing, and a tick confirms its timer is still registered before firing.
- **Orleans: two writers of the same first checkpoint no longer fail one of them.** When an
activation and its successor overlap during a failover, both can find no checkpoint row and both
insert it; the one that lost to the key threw. It now updates the row the other inserted.
- **Orleans: the partition counter works on a model that does not use snake-case names.** The
interceptor advanced the counter with SQL naming `partition_position` and its columns literally, so
a write context mapping the counter under other names failed every append. It now goes through the
context's model, as the native reader already did.
- **Orleans: the partition-counter backfill positions old entries in the order they were appended.**
It ordered each partition's history by bucket first, so a projection or saga reading across
aggregates saw the facts of one bucket before earlier facts of another. Entries are now positioned
in sequence order, as the event-sourcing-store specification already promised. A store backfilled
under 4.1.0 keeps the positions it was given; the backfill does not reposition entries.
