Failure running unit tests since upgrading to airflow 2.0 and then downgrading to 1.10.14

[meltedhead]

I upgraded to airflow 2.0 today and then realised i would need to refactor some of my code so downgraded to version 1.10.14.
Now any time i try to run any unit tests that were previously working they fail and i'm not sure why?
Running the test below always ran perfectly

`from httmock import HTTMock
from unittest import TestCase
from unittest.mock import patch, call, mock_open, MagicMock, Mock, ANY

import os.path
import os


from src.operators.modelling.language import InjestTestOperator
from airflow.hooks.base_hook import BaseHook
from airflow.hooks.postgres_hook import PostgresHook
from airflow.hooks.S3_hook import S3Hook

class TestInjestTestOperator(TestCase):
    def setUp(self):
        # hook patches
        self.open_file_mock = patch('builtins.open').start()
        self.os_path_isdir = patch.object(os.path, 'isdir').start()
        self.os_makedirs = patch.object(os, 'makedirs').start()
        self.open_file_write_mock = self.open_file_mock.return_value.__enter__.return_value.write


        # prepare the target
        self.target = InjestTestOperator(
            task_id='InjestTestOperatorTest',
            sql=None,
            postgres_conn_id='test',
            aws_conn_id='s3-conn-1',
            s3_bucket_name=‘data’,
            output_path='output/path/1')

    def tearDown(self):
        patch.stopall()

    def testTmpFolderCreationIfItDoesntExist(self):
        self.os_path_isdir.return_value = False
        self.target.execute(None)
        self.os_makedirs.assert_called_with('/tmp/modelling/test')

    def testTmpFolderNotCreatedIfItExists(self):
        self.os_path_isdir.return_value = True
        self.target.execute(None)
        self.os_makedirs.assert_not_called()`

This always worked and now constantly fails along with any other tests. This code has not been changed.

Looks like the DAGBAG_IMPORT_TIMEOUT have been upgraded in your config files. It changed to float in airflow 2.0 so value 30.0 is acceptable but for Airlfow 1.10 it was int. You need to find the place in configuration where you set it to to 30.0 and set it back to 30

Thanks! Will try that!

That's worked.
