Rig.TUnit.Caching.Hybrid

Microsoft HybridCache provider — L1 in-memory with stampede coalescing and tag invalidation. No container required.

What this package is

The Rig.TUnit adapter for Microsoft's HybridCache. HybridCacheFixture configures an HybridCache instance with sensible test defaults (60 s default TTL, 1 MiB max payload, 1024-char max key, local-cache TTL 30 s) and exposes the raw HybridCache plus a stampede coalescing test surface. L2 distributed is off by default — pair with Rig.TUnit.Caching.Redis if you want it.

When to use it

  • Testing services using Microsoft's HybridCache.
  • Verifying stampede coalescing for GetOrCreateAsync.
  • Asserting tag-invalidation via RemoveByTagAsync.
  • Not for: FusionCache (different semantics, use .Fusion) or plain IMemoryCache (use .Memory).

Prerequisites

  • .NET 10 SDK
  • Microsoft.Extensions.Caching.Hybrid 10.x (transitive)

Quick start

using Rig.TUnit.Caching.Hybrid.Fixtures;

await using var fx = new HybridCacheFixture();
await fx.InitializeAsync();

var key = $"k-{Guid.NewGuid():N}";
var value = await fx.Cache.GetOrCreateAsync(key, async _ =>
{
    await Task.Yield();
    return "computed-value";
});

Options

Property Type Default Description
DefaultExpirationSeconds int 60 Distributed-tier TTL
LocalCacheExpirationSeconds int 30 L1 (in-memory) TTL
MaximumPayloadBytes int 1_048_576 1 MiB guard
MaximumKeyLength int 1024 Key length guard

Section name: RigTUnit:HybridCache.

Fixture + helper APIs

  • Rig.TUnit.Caching.Hybrid.Fixtures.HybridCacheFixture
  • Rig.TUnit.Caching.Hybrid.Options.HybridCacheFixtureOptions
  • Rig.TUnit.Caching.Hybrid.Builder.HybridCacheRigBuilder

Per-test isolation

Per-fixture HybridCache instance. Each test owns its own cache; no shared state unless you explicitly wire an L2 distributed tier.

Parallelism + performance

  • Zero container startup.
  • GetOrCreateAsync warm hit: ~700 ns.
  • Stampede coalescing guarantees a single loader call per key within the coalescing window (~500 ms default).
  • Safe under full parallelism.

Troubleshooting

  • GetOrCreateAsync returns stale value after invalidation — check LocalCacheExpirationSeconds > 0 combined with the L2 clear; HybridCache does not broadcast invalidation events to the L1 unless an L2 is wired.
  • Value not invalidated by tag — confirm you tagged on insert: .WithTags(["orders"]) inside GetOrCreateAsync's options.

See docs/troubleshooting.md#hybrid.

Provider quirks + edge cases

  • HybridCache is a singleton in the DI container; pin it as AddSingleton if you are composing your own service graph.
  • Tag invalidation is per-instance for L1 only; L2 tag invalidation requires a compatible backplane (not shipped here).
  • Serializer is System.Text.Json by default; register custom if your values contain polymorphic types.
