 or more specific:

-Specying `models=` and `seeds=` is optional, however _if_ you specify `seeds`, you have to specify `models` too.

 Where possible, targets are being run in docker containers (this works for Postgres or in the future Spark for example). For managed services like Snowflake, BigQuery and Redshift this is not possible, hence your own configuration for these services has to be provided in the appropriate env files in `integration_tests/.env/[TARGET].env`
