JavierLopezT commented on issue #6670: [AIRFLOW-4816]MySqlToS3Operator URL: https://github.com/apache/airflow/pull/6670#issuecomment-593511992 I am stucked again with the test. Could you help me please? Sorry for bothering again ``` AssertionError: Expected call: load_file(bucket_name='bucket', filename=<MagicMock name='NamedTemporaryFile.__enter__.name' id='140026932181872'>, key='key') Actual call: load_file(bucket_name='bucket', filename=<MagicMock name='NamedTemporaryFile().__enter__().name' id='140026915240536'>, key='key') ``` The code in the operator is: ``` with tempfile.NamedTemporaryFile(mode='r+', suffix='.csv') as tmp_csv: tmp_csv.file.write(data_df.to_csv(index=self.index, header=self.header)) tmp_csv.file.seek(0) s3_conn.load_file(filename=tmp_csv.name, key=self.s3_key, bucket_name=self.s3_bucket) ``` And the testing code (its latest version) is: @mock.patch("airflow.operators.mysql_to_s3_operator.tempfile.NamedTemporaryFile") ... ``` temp_mock.assert_called_once_with(mode='r+', suffix=".csv") temp_mock.return_value.__enter__.return_value.name = "file" mock_s3_hook.return_value.load_file.assert_called_once_with(filename=temp_mock.__enter__.name, key=s3_key, bucket_name=s3_bucket) ``` I have tried also with: ``` mock_s3_hook.return_value.load_file.assert_called_once_with(filename="file", key=s3_key, bucket_name=s3_bucket) ``` and ``` mock_s3_hook.return_value.load_file.assert_called_once_with(filename=temp_mock.name, key=s3_key, bucket_name=s3_bucket) ```
