Summary

• Container-backed test projects declare their CookieCrumble resource as an xUnit [assembly: AssemblyFixture], so a run starts one container per assembly instead of one per test class: Data.Raven.Tests, the four Data.MongoDb.*.Tests projects, PersistedOperations.Redis.Tests, PersistedOperations.AzureBlobStorage.Tests, Subscriptions.Postgres.Tests, Subscriptions.Redis.Tests, Fusion.Subscriptions.NATS.Tests, and Fusion.Subscriptions.Redis.Tests. The two NATS-over-HTTP classes in Fusion.AspNetCore.Tests share one collection fixture instead of starting a container per test.
• ContainerResource<T> gains a DisposeAsyncCore hook that runs before the container is disposed. RedisResource caches one multiplexer and MongoResource one client, both owned and disposed by the resource. NatsResource.CreateStreamAsync returns a uniquely named JetStream stream that deletes itself on dispose, replacing the per-test stream helpers in three test projects.
• RedisIntegrationTests scopes its PUBSUB CHANNELS probe to the subscription's own channel so the unsubscribe test holds on a server shared with the topic-prefix class.

Test plan

• Full suite of every converted project passes: Raven 19, Mongo Projections 30 / Sorting 23 / Paging 39 / Filters 122, PersistedOperations Redis 19 / Azure Blob 12, Subscriptions Postgres 73 / Redis 19 (three consecutive runs), Fusion NATS 9 / Redis 7, Fusion.AspNetCore 546 with the 49 pre-existing skips, Fusion.Execution NATS gateway test 1.
• Container count sampled during each run shows one container per assembly, down from three for Raven, up to thirteen for Mongo Filters, and eight per-test starts for Fusion.AspNetCore.
• The NATS-over-HTTP tests on a shared server without stream cleanup fail six of eight with subjects overlap with an existing stream; with the self-deleting stream all eight pass.

🟢 Approval recommended

The changes are internally consistent across the converted test assemblies and the new shared-resource disposal hooks cleanly manage cached clients without introducing behavioral issues in the updated tests.

Pull request overview

This PR reduces container churn in integration tests by moving container-backed resources to xUnit assembly fixtures (one container per test assembly) and by making shared container resources own and reuse their client connections safely across all tests in that assembly.

Changes:

• Convert multiple test projects from per-class IClassFixture<T> usage to [assembly: AssemblyFixture(typeof(...))] for container-backed resources.
• Add a DisposeAsyncCore hook to ContainerResource<T> and update Redis/Mongo/NATS resources to cache and dispose their client connections once per fixture.
• Introduce NatsResource.CreateStreamAsync + NatsStream to create uniquely named, self-deleting JetStream streams and update NATS tests to use it; also scope the Redis PUBSUB CHANNELS probe to the subscription’s own channel.
