Rig.TUnit.Caching.Memory

IMemoryCache-backed CacheFixtureBase — single-node in-memory cache. Zero-container speed-of-light tier.

What this package is

The simplest cache provider: a standard Microsoft.Extensions.Caching. Memory.IMemoryCache wrapped in a Rig.TUnit fixture. No container, no distributed coordination, no backplane — just a dictionary with TTL + size-limit eviction and the CacheRigContract subset that applies to single-node caches.

When to use it

Tests that need a trivially-fast cache for sanity-check assertions.
In-process caching scenarios where L2 distribution is deliberately absent.
Running the CacheRigContract in its fastest mode.
Not for: distributed coherency testing (nothing to coordinate); use Rig.TUnit.Caching.Fusion with an L2 Redis backplane.

Prerequisites

.NET 10 SDK
Microsoft.Extensions.Caching.Memory (transitive)

Quick start

using Rig.TUnit.Caching.Memory.Fixtures;

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

fx.Cache.Set("k", "v", TimeSpan.FromSeconds(30));

Options

Property	Type	Default	Description
`SizeLimit`	`long?`	`null`	`IMemoryCache.SizeLimit`
`CompactionPercentage`	`double`	`0.25`	% evicted on size-pressure
`DefaultTtl`	`TimeSpan`	`5m`	Applied when entry has no explicit TTL

Fixture + helper APIs

Rig.TUnit.Caching.Memory.Fixtures.MemoryCacheFixture
Rig.TUnit.Caching.Memory.Options.MemoryCacheFixtureOptions
Rig.TUnit.Caching.Memory.Builder.MemoryCacheRigBuilder

Per-test isolation

Per-fixture IMemoryCache instance. Each test owns its own cache; nothing is shared. Safe under full parallelism without any extra work.

Parallelism + performance

Zero container startup.
Set/Get: ~200 ns.
Safe under full parallelism.

Troubleshooting

Coherency assertions N/A — CacheAssert.Coherent(…) is a no-op against a single-node cache. The contract suite's skipped entries are documented; do not treat the skip as a regression.
Size-limit evictions not seen — SizeLimit must be combined with per-entry Size; entries without a Size are never size-evicted.

See docs/troubleshooting.md#memory-cache.

Provider quirks + edge cases

IMemoryCache.Remove(object) takes object, not string — typed wrappers are your friend.
AbsoluteExpirationRelativeToNow on Set measures from enqueue time, not eviction-check time. A 5 s expiry set at T=0 evicts at T=5.
