HOWTO

Want to run the Seafowl tests locally? This HOWTO is intended to help you more easily understand what the tests need.

In short, invoking cargo test depends on:

  • the containers in docker-compose.yml
  • A Postgres instance (or equivalent)
  • DATABASE_URL env var pointing to that Postgres instance

macOS

Get the containers running

After installing Docker for Mac please make sure you cd into the Seafowl repo and run

docker compose up -d

Make Postgres available

Next, make a Postgres instance available.

One way to do that is to via sgr, which can be installed a few different ways (including Homebrew).

brew install sgr
sgr engine add

At the time of writing (May 2023) docker ps should look something like this:

CONTAINER ID   IMAGE                      COMMAND                  CREATED             STATUS             PORTS                    NAMES

Provide the DATABASE_URL environment variable

Finally, run

export DATABASE_URL=postgresql://sgr:1234@localhost:6432/splitgraph

(where '1234' is whatever password you assigned in previous step)

You're done

You're now ready to run the tests! 🎉
