I have a problem with unittest. The patched method does not return a list of tuples, but only one tuple:
My code
from date import Date
from ditreport import DIT_report
from unittest import TestCase
from unittest.mock import patch, Mock
def mock_get_uuid_messages_with_tmpls():
result = [('43e89d3a-af91-465f-a2db-3147988d1168',), ('93963bf6-9f75-4ffe-80e6-745307ef0a10',),
('88e68d67-8969-4059-9f6c-ff161879eb38',), ('39191cbd-79bb-483a-8df7-04aaf72253f1',),
('44a685c4-fb12-4431-ae18-3fb220e4d3e7',), ('3eef8189-7509-4dc1-9d71-c04f1cfc0d88',),
('4736beae-aa55-4bb3-b41d-3f94b1b178d1',), ('260db4a6-aab8-4d34-b293-cbf5fe6c7400',),
('7b73dfe0-5b8a-4a63-8607-43827eeac4c0',), ('fb51668f-0d2f-4958-911d-07d57a73fe56',)]
return result
class TestDIT_report(TestCase):
def setUp(self):
self.date_start='2020-01-12'
self.date_end = '2020-02-01'
self.configfile='config/config.def.xml'
self.param='covid'
self.report = DIT_report(self.date_start, self.date_end, self.configfile)
@patch('ditreport.DIT_report.get_uuid_messages_with_tmpls', side_effect=mock_get_uuid_messages_with_tmpls())
def test_get_uuid_messages_with_tmpls(self, get_uuid_messages_with_tmpls):
messages_uuid = get_uuid_messages_with_tmpls()
self.assertEqual(10,len(messages_uuid))
messages_uuid should get a list of ten tuples but get the first tuple

During handling of the above exception, another exception occurred:

Why do I get this error? Maybe I missed what parameter? But I have a similar code and it returns a normal list of tuples.
