Terry J. Reedy <[email protected]> added the comment:
Without lines numbers, I cannot test which of the two identical asserts failed.
Either comments or msg arguments will differentiate. Nor can I run snippets
from two different files. Here is a minimal reproducible self-contained code
that demonstrates the claim (which I verified on 3.9 and current master).
import unittest
from unittest.mock import Mock
class SomethingElse(object):
def __init__(self):
self._instance = None
@property
def instance(self):
if not self._instance:
self._instance = 'object'
class Test(unittest.TestCase):
def test_property_not_called_with_spec_mock(self):
obj = SomethingElse()
self.assertIsNone(obj._instance, msg='before') # before
mock = Mock(spec=obj)
self.assertIsNone(obj._instance, msg='after') # after
unittest.main()
