Bug description:
Version: master(20160527)
In case cinderclient.tests.unit.test_base.BaseTest.test_eq
self.assertNotEqual does not work.
Class base.Resource defines __eq__() built-in function, but does not define
__ne__() built-in function, so self.assertEqual works but self.assertNotEqual
does not work at all in this test case.
steps:
1 Clone code of python-cinderclient from master.
2 Modify the case of unit test: cinderclient/tests/unit/test_base.py
line50--line62.
def test_eq(self):
# Two resources with same ID: never equal if their info is not equal
r1 = base.Resource(None, {'id': 1, 'name': 'hi'})
r2 = base.Resource(None, {'id': 1, 'name': 'hello'})
self.assertNotEqual(r1, r2)
# Two resources with same ID: equal if their info is equal
r1 = base.Resource(None, {'id': 1, 'name': 'hello'})
r2 = base.Resource(None, {'id': 1, 'name': 'hello'})
# self.assertEqual(r1, r2)
self.assertNotEqual(r1, r2)
# Two resoruces of different types: never equal
r1 = base.Resource(None, {'id': 1})
r2 = volumes.Volume(None, {'id': 1})
self.assertNotEqual(r1, r2)
# Two resources with no ID: equal if their info is equal
r1 = base.Resource(None, {'name': 'joe', 'age': 12})
r2 = base.Resource(None, {'name': 'joe', 'age': 12})
# self.assertEqual(r1, r2)
self.assertNotEqual(r1, r2)
Modify self.assertEqual(r1, r2) to self.assertNotEqual(r1, r2).
3 Run unit test, and return success.
After that, I make a test:
class Resource(object):
def __init__(self, person):
self.person = person
def __eq__(self, other):
return self.person == other.person
r1 = Resource("test")
r2 = Resource("test")
r3 = Resource("test_r3")
r4 = Resource("test_r4")
print r1 != r2
print r1 == r2
print r3 != r4
print r3 == r4
The result is :
True
True
True
False
Whether r1 is precisely the same to r2 or not, self.assertNotEqual(r1,
r2) return true.So I think self.assertNotEqual doesn't work at all in
python2 and should be modified.
