Gemini Developers Guide

Running Gemini

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

./scripts/gemini-launcher

The script starts a Scylla cluster as the system under test and an Apache Cassandra clusters a test oracle using docker-compose and starts a Gemini run using the two clusters.

You can also launch the clusters yourself with:

docker-compose -f scripts/docker-compose.yml up -d

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

gemini \\
--test-cluster=$(docker inspect --format='{{ .NetworkSettings.Networks.gemini.IPAddress }}' gemini-test) \\
--oracle-cluster=$(docker inspect --format='{{ .NetworkSettings.Networks.gemini.IPAddress }}' gemini-oracle)

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

The suite has one build tag that controls what is being run: slow. This tag should be used for standard unit tests that for some reason take a long time to run perhaps because they do fuzzing or quick checks.

Run these tests like this:

go test -v -race -tags slow
