Is there any way to skip a model from running if its parent nodes freshness tests fail?

Hey! If you're using Elementary freshness tests, and you set the severity to

error

, then yes — when you run

dbt build

, dbt will skip building downstream models that depend on the source whose freshness test failed. This works because Elementary freshness tests are compiled as regular dbt test nodes. So when a test with

severity: error

fails, it causes the upstream node to fail, and

dbt build

will not proceed with downstream dependencies — which sounds like exactly what you're aiming for.
