One comment to that is (via #19578) that users also use (and quite often) `airflow tasks test` to run single tasks for a particular DAG. I think while we could get-by with backfil on `dags test` , this will not be the case for `tasks test`- and we need to figure out how to pass the data_interval to that comand as well. I think from the [docs](https://airflow.apache.org/docs/apache-airflow/stable/howto/timetable.html?highlight=timetables#define-scheduling-logic) the intention was that `infer_data_interval` for the custom timetable will do that, but it does not seem to be plugged-in currently (and `tasks test` with custom timetables fails as it cannot infer the interval). I think if we solve it for `tasks test`, the same solution could be used for `dags test`. One good thing about `dags test` also is that it uses "DebugExecutor" and did not leave traces in the DB after it was executed (or so I thought at least - and for sure that was the itention of the `dag tests` command. I am not sure if this assumption holds true still - or needs to be 'fixed". But the idea was that you run the whole dag this way, but that it will not be stored in the database. I am not sure if this is something that we want to `mix` with backfill - though. For me `dags tests` still has a good use here. -- This is an automated message from the Apache Git Service.
