Overview

Redis is the dominant application-tier cache. Per 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.
