mik-laj edited a comment on issue #6446: [AIRFLOW-5773] Migrate AWS Athena components to /providers/aws [AIP-21] URL: https://github.com/apache/airflow/pull/6446#issuecomment-546684480 @BasPH This tests backwards compatibility. Ensures that the class is still available in the old location. When loading the module from the old location, a message with information about the new location must also be reported. There are also tests in the same file that check if a message is reported when you try to use a class with the old name. This applies to the next steps when changing operator names. This test is very important because it makes it much easier to verify the correctness of the change. Another saying. This facilitates the boring review process.
