For our integration tests which require a running substrate node, we should consider running a tagged docker image of substrate: https://hub.docker.com/r/parity/substrate/tags. Also see https://github.com/paritytech/pallet-contracts-waterfall#using-a-docker-image-of-substrate-for-testing

That way we do not need to maintain all modules in the local test node.
