I noticed that my development environment had a bunch of junk keys in redis that were attributable to things I did simultaneously in my test environment.
The solution is to switch to separate databases for everything in the test ENV - even DB's used for minor features.
redis_db = Rails.env.test? ? 2 : 1
Redis.new(url: 'redis://localhost:6379', db: redis_db)
