If you know and use nix, we recommend using our flake.nix file.
All you have to do is
$ nix develop
Get setup with Nix: https://nixos.org/download#download-nix
Start the Nix daemon if the install tells you that it's not compatible with your init system:
$ nix daemon
If this is your first time setting up Nix you'll want to use the
flakes feature and not have to enable on the CLI every time:
$ echo 'experimental-features = nix-command flakes' >> ~/.config/nix/nix.conf
This works for the multi-user setup and the single-user setup.
Once your development environment is setup you should be able to use
the test target in the Makefile to run ./scripts/run-tests.sh
which will source environment.sh, connect to the PostgreSQL database
from there, and setup and run the integration tests:
$ make test
