Gemini Developers Guide

Running Gemini

The easiest way to run Gemini for development is to use:

./scripts/test.sh <test parameters>

The script starts two single node scylla clusters as the system under test and as an oracle using docker-compose and starts a Gemini run against these clusters

You can make it to run Cassandra as an oracle:

./scripts/test.sh cassandra <test parameters>

You can also launch the clusters yourself with:

./scripts/prepare-environment.sh

And run Gemini against the test oracle and system under test clusters as follows:

./scripts/run-gemini-test.sh <test parameters>

Running unit tests

Geminis own test suite so far only consists of unit tests. Run these in the standard Go way:

go test -v -race -cover
