The Vert.x Redis client provides an asynchronous API to interact with a Redis data-structure server.
In order to run the tests, it is expected that a simple cluster is setup in the test environment, you can do this by running the following container:
docker run -d \
-e 'IP=127.0.0.1' \
-e 'STANDALONE=true' \
-e 'SENTINEL=true' \
-p '7000-7007:7000-7007' \
-p '5000-5002:5000-5002' \
grokzen/redis-cluster:latest
The documentation can be read from the official vert.x Documentation.
