Running tests

To quickly run tests, you can provide the LILY_TEST_DB envvar and execute make test like so:

LILY_TEST_DB="postgres://postgres:password@localhost:5432/postgres?sslmode=disable" make test

For more, manual test running, you could also prepare your environment in the following way:

Create a new DB in postgres for testing:

CREATE DATABASE lily_test;

Migrate the database to the latest schema:

lily migrate --db "postgres://username@localhost/lily_test?sslmode=disable" --latest

Run the tests:

LILY_TEST_DB="postgres://username@localhost/lily_test?sslmode=disable" go test ./...
