assert断言方法python,Python 2.7中的断言不适用于我的示例assertIn

I have python 2.7 installed on my Mac. (verified by running python -v in terminal)

When I try to use any of the new 2.7 assert methods I get AtributeError. I have looked at http://docs.python.org/2/library/unittest.html and can't find anything. The Asserts that come with 2.6 all work Ex Self.AssertEqual (x,x)

Below is my code. When I call the assertIn I get the below message.

* Test complete (ERROR): test012_Add_user2 (__main__.TestSuite)

(, AttributeError("'TestSuite' object has no attribute 'assertIn'",), )

Traceback (most recent call last):

File "/Users/drlazor/Documents/AIM/7-16/oscar/qa/clients/TRAVOLTA/scripts_iphone/Add_Favorites.sikuli/Add_Favorites.py", line 112, in test012_Add_user2

self.assertIn (foo, foo2)

AttributeError: 'TestSuite' object has no attribute 'assertIn'

below is my code

import unittest

import datetime

from sikuli import *

scriptName = os.path.basename(sys.argv[0])

addImagePath( os.path.join("scripts", scriptName) )

class TestSuite (unittest.TestCase):

#Need to add some Iphone clearing of favorites

def test001_start_IPhone(self):

logger.info (" Start aim iphone application")

showEnvironmentSettings()

a.startApp()

version = a.login(username1, password)

myTest.results['deviceVersion'] = version

wait(2)

def test012_Add_user2(self):

logger.info ("Add User 2 to the Favorites")

a.mFriends_Favorites_addNewFavs((username3[-3:]))

Fav=a.mFriends_Favorites_getAllFavs()

logger.info("assertin is tried.... will see")

#assertIn(Fav, Fav2)

self.assertIn ("foo", "foo2") #foo

for item in Fav:

logger.info (item)

logger.info ("HSJDKSKJDHSAKJDHSAKJDHSA LOOOP 2")

if (username3[-3:])not in item:

logger.info(item)

logger.info(username3[-3:])

logger.info ("dkfjlfjskl FOUND 062")

self.assert ("The screenName %s was not added to the list" %username3)

def test016_Ck_Favorite_presence(self):

pres=a.mFriends_Favorites_checkUserPresence(username3[-3:])

self.assertEqual( pres, 'Offline' )

logger.info("Presence state is '%s'" %pres)

if __name__ == '__main__':

logger.info("Running test: "+scriptName)

a = IPHONE()

b = BROWSER()

c = SAWS()

myTest = TestSuiteRunner(TestSuite, scriptName, testDescription, device=device)

myTest.runtest()

I suspect that your code is not running in the version of Python that you think it is. If you add the following test case:

def test_python_version(self):

import sys

assert sys.version_info[0:3] >= (2,7,0)

If that test case fails, then you're not running on a version of Python new enough to contain self.assertIn().
