Stratara.Validation

License: FSL-1.1-MIT (Functional Source License — source-available; converts to MIT after 2 years). Not OSI-approved OSS.

Vendor-neutral request validation for Stratara's CQRS pipeline. A mediator pipeline behavior runs your IValidator<T> implementations before the handler and throws an aggregated StrataraValidationException when validation fails — no third-party validation dependency in the default path.

Quick start

// 1. Register the behavior (outermost) + discover validators.
builder.Services
    .AddStrataraValidation()
    .AddValidatorsFromAssemblyContaining<IAppMarker>();

// 2. Write a validator (the contracts live in Stratara.Abstractions.Validation).
public sealed class CreateOrderValidator : IValidator<CreateOrder>
{
    public ValueTask<ValidationResult> ValidateAsync(CreateOrder cmd, CancellationToken ct = default)
        => ValueTask.FromResult(string.IsNullOrWhiteSpace(cmd.CustomerId)
            ? new ValidationResult([new ValidationFailure(nameof(cmd.CustomerId), "Customer is required.")])
            : ValidationResult.Success);
}

// 3. Catch the failure in your global handler and map it to your error model.
catch (StrataraValidationException ex)
{
    // ex.Failures -> RFC-7807 ProblemDetails 400, your error codes, etc.
}

How it works

  • AddStrataraValidation() registers IPipelineBehavior for both request shapes (IRequest and IRequest<TResult>). Register it before other behaviors so validation runs outermost — before authorization, auditing, and the handler.
  • All validators for a request run; their failures are aggregated.
  • Severity policy: only ValidationSeverity.Error blocks (throws StrataraValidationException). Warning and Info failures pass through and are logged.

Contracts

The validation contracts (IValidator<T>, ValidationResult, ValidationFailure, ValidationSeverity, StrataraValidationException) live in Stratara.Abstractions (namespace Stratara.Abstractions.Validation) so consumers can implement validators and catch the exception without referencing this behavior package.

The contract shape is FluentValidation-compatible; an optional Stratara.Validation.FluentValidation adapter can be shipped to plug FluentValidation validators into the same pipeline.

### 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.
