1153 Asset Checks Dba80fcc

Asset Checks

dbt tests are loaded as Dagster asset checks by default (enabled in dagster-dbt 0.23.0+).

Enabling Source Tests

By default, only tests on dbt models are loaded as checks. To include tests on sources:

Component approach:

attributes:
  translator_settings:
    enable_source_tests_as_checks: true

Pythonic approach:

from dagster_dbt import DagsterDbtTranslator, DagsterDbtTranslatorSettings

translator = DagsterDbtTranslator(
    settings=DagsterDbtTranslatorSettings(
        enable_source_tests_as_checks=True
    )
)

@dbt_assets(
    manifest=my_dbt_project.manifest_path,
    dagster_dbt_translator=translator
)
def my_dbt_assets(context, dbt: DbtCliResource):
    yield from dbt.cli(["build"], context=context).stream()

Singular Tests with Multiple Dependencies

For singular tests that depend on multiple models, specify the target model in the test's config block:

{{
    config(
        meta={
            'dagster': {
                'ref': {
                    'name': 'customers',
                    'package': 'my_dbt_assets',
                    'version': 1,
                },
            }
        }
    )
}}

SELECT ...

The ref structure mirrors dbt's ref function parameters. Without this metadata, the test still runs but emits an AssetObservation instead of an asset check result.
