-------------------------------------
Summary: warning.catch_warning should not be use in our code
Key: AIRFLOW-6226
URL: https://issues.apache.org/jira/browse/AIRFLOW-6226
Project: Apache Airflow
Issue Type: Bug
Components: ci
Affects Versions: 1.10.6, 2.0.0
Reporter: Jarek Potiuk
Sometime we use warning.catch_warnings in our code directly.
As explained in [https://blog.ionelmc.ro/2013/06/26/testing-python-warnings/]
warnings are cached in "__warningregistry__" and if warning is emitted, it is
not emited for the second time.
Therefore warning.catch_warnings should never be used directly in our test code.
