redis-cache-tests SKILL.md skillA
redis-cache-tests from testland/qa is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add testland/qa/redis-cache-tests@git:20260813.2e5e33bPins git:20260813.2e5e33b in mdr.lock. Pin the fingerprint instead.

Wraps Redis cache testing: EXPIRE / PEXPIRE / TTL verification (Redis 7+ NX/XX/GT/LT flags), cache-aside write-then-invalidate (write source → DEL key → assert fresh read), eviction under memory pressure (maxmemory + allkeys-lru), pub/sub invalidation across nodes, and tenant key-namespacing. Use when Redis is the app's primary cache. For the CDN/browser HTTP tier use cdn-cache-purge-tests; a runnable test, not the cache-coherence-patterns-reference catalog…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# redis-cache-tests
## Overview
Redis is the dominant application-tier cache. Per
[redis.io/docs/latest/commands/expire/](https://redis.io/docs/latest/commands/expire/),
keys get TTLs via `EXPIRE`, `PEXPIRE`, or `EXPIREAT` - with
Redis 7+ flags `NX` / `XX` / `GT` / `LT` controlling conditional
expiry.
This skill wraps test patterns against a real Redis instance
(via testcontainers or a dedicated test cluster) - **not** a
mock. Mocks lose the eviction-policy + TTL-tick + pub-sub
behaviours that real bugs hide in.
## When to use
- Tests for code that uses Redis as a cache.
- Verifying eviction policy under memory pressure.
- Tenant-namespace tests for cache-key isolation.
- Stampede-mitigation tests per
`cache-coherence-patterns-reference` references/stampede.md.
## Authoring
### Install
```bash
pip install redis testcontainers # Python
npm install --save-dev ioredis testcontainers # Node
```
### Real-Redis test fixture (Python)
```python
import pytest
import redis
from testcontainers.redis import RedisContainer
@pytest.fixture(scope="session")
def redis_url():
with RedisContainer("redis:7-alpine") as r:
yield r.get_connection_url()
@pytest.fixture

How to install
mdr add testland/qa/redis-cache-tests@sha256:4dd8f67154b1f7d7The line at the top of this page pins the label git:20260813.2e5e33b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
