  3. Checkout great expectations ( https://greatexpectations.io/ ). You basically run assertions on your data. It auto-generates documentation for you and you can also store results of your validations in a flat file or database. I think there are dbt modules that try to mimic great expectations' validation but I like the docs that come with great expectations

  5. Testing Pipeline in Airflow is bit pain, but great expectation makes runtime pipeline validation much easier. https://greatexpectations.io For unit/integration tests we ended up doing lot of Docker in Docker setup.
