To run integration tests you need to use a postgres database. The fastest way is to obtain it from docker.
Use the following command:
docker run --name 'pgactix' -p 5433:5432 -e POSTGRES_PASSWORD=pgactix -e POSTGRES_USER=pgactix -d postgres\
Once the db has started, load the script ./test_resources/pgactix.dump with this command:
docker run -ti --rm --link pgactix:pgactix -e PGPASSWORD=pgactix -v $(pwd)/test_resources:/init postgres /bin/bash
From inside the container run this command to create tables and upload test data:
psql -h pgactix -U pgactix < /init/pgactix.dump
