Key: AIRFLOW-4308
URL: https://issues.apache.org/jira/browse/AIRFLOW-4308
Project: Apache Airflow
Issue Type: Bug
Reporter: Jarek Potiuk
It seems that one of the tests is failing in Python 3.5 vs. Python 3.6 related
to different behaviour of python with regards to TZ environment variable:
[https://bugs.python.org/issue30062]
We've yet have to determine whether this is a problem with the test or Airflow
code:
The test below works fine in Python 3.5.
{code:java}
+ nosetests
tests.models.test_dag:DagTest.test_following_previous_schedule_daily_dag_CEST_to_CET
.
----------------------------------------------------------------------
Ran 1 test in 0.005s
OK
{code}
But it fails in Python 3.6:
{code:java}
nosetests
tests.models.test_dag:DagTest.test_following_previous_schedule_daily_dag_CEST_to_CET
F
======================================================================
FAIL: Make sure DST transitions are properly observed
