Rig.TUnit.Caching.Redis

Redis-as-cache fixture (primary home for RedisFixture) with RedisBackplaneCapture for pub/sub cache-invalidation tests.

What this package is

The Rig.TUnit Redis-as-cache provider. Primary home for RedisFixture — the same container is re-used by Rig.TUnit.Databases.NoSql.Redis in its KV role. Exposes UseRedisCache(…) (no bare UseRedis — ADR-007 forces the caller to declare intent cache vs KV). Ships RedisBackplaneCapture which subscribes to a pub/sub channel and records cache-invalidation events, so tests can assert "publishing orders:cache-invalidate evicts the L1 on every node".

When to use it

  • Testing distributed-cache coherency with pub/sub-based invalidation.
  • L2 backing for FusionCache / HybridCache distributed-tier tests.
  • Asserting cache hit-rate targets against real Redis.
  • Not for: KV-store scenarios — use Rig.TUnit.Databases.NoSql.Redis.

Prerequisites

  • .NET 10 SDK
  • Docker Desktop / Colima (Redis image ~120 MB)
  • StackExchange.Redis (transitive)

Quick start

using Rig.TUnit.Caching.Redis.Fixtures;
using StackExchange.Redis;

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

var db = ConnectionMultiplexer.Connect(fx.ConnectionString).GetDatabase();
await db.StringSetAsync("cache:orders:42", "{}", TimeSpan.FromMinutes(5));

Options

Property Type Default Description
Image string "redis:7-alpine" Image
StartupTimeoutSeconds int 30 Redis boots fast
Password string? null Off in dev mode
BackplaneChannel string "cache-invalidate" Pub/sub channel

Fixture + helper APIs

  • Rig.TUnit.Caching.Redis.Fixtures.RedisFixture
  • Rig.TUnit.Caching.Redis.Options.RedisCacheFixtureOptions
  • Rig.TUnit.Caching.Redis.Builder.RedisCacheRigBuilder
  • Rig.TUnit.Caching.Redis.Helpers.RedisBackplaneCapture

Per-test isolation

Per-test key prefix cache:{IsolationKey:short}:*. Teardown via SCAN + DEL on the prefix. Pub/sub channels are per-fixture to avoid cross-test subscriber leakage.

Parallelism + performance

  • First-run pull: ~5 s.
  • Warm startup: ~1 s.
  • Per-op Get/Set: ~150 µs (in-process latency dominated).
  • Parallelism: 8+ concurrent tests — key-prefix isolation makes this trivially safe.

Troubleshooting

  • TimeoutException on first op — ConnectionMultiplexer.Connect is synchronous and blocks until the initial topology discovery completes; under heavy parallel startup this can exceed the default 5-second timeout. Raise SyncTimeout in your config.
  • Backplane capture missed events — ISubscriber.Subscribe is eventually-consistent; poll for the subscription to be active before publishing (fixture does this but a custom wire-up must too).

See docs/troubleshooting.md#redis-cache.

Provider quirks + edge cases

  • Redis pub/sub is fire-and-forget — a subscriber started after a publish misses the message. Always subscribe before triggering the event the test expects.
  • KEYS * is the classic production foot-gun; the fixture-internal teardown uses SCAN (O(1) per batch) instead.
  • Cache-vs-KV split rationale: ADR-007. Bare UseRedis does not exist; this is deliberate.
