… postgres max Was getting test failures due to resulting lengthy model names being created by unit test task in the functional test
…package of unit test This is necessary because when we create the shadow manifest for the running the unit test node, the included models whether direct or external, get rewritten as being in the unit test's package.
…external node point to it Previously I was getting an error about the columns for the external model not being fetchable from the database via the macro `get_columns_in_relation`. By creating a seed for the tests, which creates a table in postgres, we can then tell the external model that it's database schema and identifier (the relation) is that table from the seed without make the seed an actual dependency of the external model in the dag.
External nodes generally don't have paths, but in unit tests we write out all models to sql files (as this allows us to test them). Thus external nodes need to have their paths set.
This is necessary because when executing a unit tests, the columns associated with a model in the database are retrieved. For this to be possible, the model must exist in the database, thus we must run the associated models at least once first.
