Review comment:
I agree in principle. It should be as you described. But currently we face
different reality. Solving it in the way you describe is much bigger task.
I just want to solve current tests not to show failures where there are no
failures at all. Failing exception in "log" is not a good "test" so it does not
hide the problem. Logs should never "detect" a problem - they should print the
current state of the object and not randomly fail.
Right now in logs you see unrelated failures, you have inconsistency in the
way how those attributes are treated - and sometimes you think those are the
problems with tests - where they aren't.
So right now I am not trying to solve this "bigger" problem only the small
one. But I created
the issue and marked you there
https://issues.apache.org/jira/browse/AIRFLOW-6640 to solve the bigger issue.
