# AIRFLOW-1893 - Originally, impersonation tests were incomplete missing the use case when
# DAGs access custom packages usually made available through the PYTHONPATH environment
# variable. This file includes a DAG that imports a custom package made available and if
# run via the previous implementation of impersonation, will fail by not being able to
# import the custom package.
# This DAG is used to test that impersonation propagates the PYTHONPATH environment
# variable correctly.
