I have two files
spike.py
class T1(object):
def foo(self, afd):
return "foo"
def get_foo(self):
return self.foo(1)
def bar():
return "bar"
test_spike.py:
from unittest import TestCase
import unittest
from mock import patch, MagicMock
from spike import T1, bar
class TestStuff(TestCase):
@patch('spike.T1.foo', MagicMock(return_value='patched'))
def test_foo(self):
foo = T1().get_foo()
self.assertEqual('patched', foo)
@patch('spike.bar')
def test_bar(self, mock_obj):
mock_obj.return_value = 'patched'
bar = bar()
self.assertEqual('patched', bar)
if __name__ == "__main__":
unittest.main()
When I run python test_spike.py
, the first test case would pass, but the second would fail.
and I switch to use nosetests test_spike.py
, then both two are failed.
I don't understand how this happened? These cases supposed to pass all.
Access bar
using spike.bar
. Imported bar
is not affected by mock.patch
.
