Suggestion: Use docker-based redis for tests

[ClaudiuCeia]

Hi team,

I sent a small PR today and I was confused about not being able to run tests. I eventually figured out that the tests expect docker to be installed locally. I understand why the tests need to be integration tests, but I think it would help if tests could run against a docker-based redis instance (or cluster) to avoid installing and messing with the local install.

Maybe a docker-compose.yml that you just need to docker compose up -d before running the tests, based on the official redis images?
