All tests are currently built around a 6 redis server cluster setup (3 masters + 3 slaves). One server must be using port 7000 for redis cluster discovery.
The easiest way to setup a cluster is to use either a Docker or Vagrant. They are both described in [Setup a redis cluster. Manually, Docker & Vagrant](docs/Cluster_Setup.md).
To run all tests in all supported environments with tox read this [Tox multienv testing](docs/Tox.md)
