Miniredis
Pure Go Redis server for Go unittests
...It saves you from using mock code, and since the redis server lives in the test process you can query for values directly, without going through the server stack. There are no dependencies on external binaries, so you can easily integrate it in automated build processes. Since miniredis is intended to be used in unittests TTLs don't decrease automatically. You can use TTL() to get the TTL (as a time.Duration) of a key. It will return 0 when no TTL is set. Miniredis will use math/rand's global RNG for randomness unless a seed is provided by calling m.Seed(...). If a seed is provided, then miniredis will use its own RNG based on that seed.
