  +# Running test suite
  +
  +The test suite requires postgres to be running in the correct configuration. The easiest way to do this is with docker:
  +
  +1. Install `docker` and `docker-compose`.
  + 1. On ubuntu: `sudo apt install docker.io docker-compose`.
  +1. Make sure your user has permissions for docker.
  + 1. On ubuntu: ``sudo usermod -aG docker $USER``
  +1. Change to top-level directory of `rust-postgres` repo.
  +1. Run `docker-compose up -d`.
  +1. Run `cargo test`.
  +1. Run `docker-compose stop`.
