   you have erros:
   ```
   ImportError while importing test module '/opt/airflow/tests/providers/google/cloud/operators/test_mysql_to_gcs.py'.
   Hint: make sure your test modules/packages have valid Python names.
   Traceback:
   tests/providers/google/cloud/operators/test_mysql_to_gcs.py:24: in <module>
       from _mysql_exceptions import ProgrammingError
   E   ModuleNotFoundError: No module named '_mysql_exceptions'
   ```
   
   you need to make modifications to the code to get it working as there were breaking changes in `PyMySQL`
   https://github.com/PyMySQL/mysqlclient-python/blob/master/HISTORY.rst
   
   the change related to the error that you get is:
   _mysql and _mysql_exceptions modules are moved under MySQLdb package. (https://github.com/PyMySQL/mysqlclient-python/pull/293)
