Airflow Python Unit Test? : <p>I'd like to add some unit tests for our DAGs, but could not find any. Is there a framework for unit test for DAGs? There is an End-to-End testing framework that exists but I guess it's dead: <a href="https://issues.apache.org/jira/browse/AIRFLOW-79" rel="noreferrer">https://issues.apache.org/jira/browse/AIRFLOW-79</a>. Please suggest, Thanks!</p>
