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

I am trying some Python with selenium, I have some defined tests in simpleUsageUnittest.py:

import unittest import time from selenium import webdriver from selenium.webdriver.common.keys import Keys class PythonOrgSearch(unittest.TestCase): def setUp(self): self.driver = webdriver.Firefox() # @unittest.skip("skip test_001") def test_001_search_in_python_org(self): driver = self.driver driver.get("http://www.python.org") self.assertIn("Python", driver.title) elem = driver.find_element_by_name("q") elem.send_keys("selenium") elem.send_keys(Keys.RETURN) # @unittest.skip("skip test_002") def test_002_goole_and_stack_test_test(self): driver_g = self.driver driver_g.get("http://www.google.com") self.assertIn("Google", driver_g.title) body_g = driver_g.find_element_by_tag_name("body") body_g.send_keys(Keys.CONTROL + 't') driver_g.get("http://stackoverflow.com") self.assertIn("Stack", driver_g.title) def tearDown(self): self.driver.close() if __name__ == "__main__": unittest.main(warnings = 'ignore') 

Alone this set is working perfectly, but then I am trying to create some suite, testTestSuite.py:

import unittest import simpleUsageUnittest import sys def suite(): testSuite = unittest.TestSuite() testSuite.addTest(simpleUsageUnittest.PythonOrgSearch.setUp) testSuite.addTest(simpleUsageUnittest.PythonOrgSearch.test_001_search_in_python_org) testSuite.addTest(simpleUsageUnittest.PythonOrgSearch.test_002_goole_and_stack_test_test) testSuite.addTest(simpleUsageUnittest.PythonOrgSearch.tearDown) return testSuite if __name__ == "__main__": result = unittest.TextTestRunner(verbosity=2).run(suite()) sys.exit(not result.wasSuccessful()) 

And while running this suite I encounter AttributeError: 'TextTestResult' object has no attribute 'assertIn', and since I dont exactly understand it I cannot fix it ;) If I delete assertIn lines in simpleUsageUnittest.py - then it is working again, but it is of course not what I want to do! Also Asserts in Python 2.7 not working for me example assertIn was not a big help since I am using Python 3.3.5 and Selenium 2.41.0. Can someone explain it to me? Or direct what attributes can I use to save my assert? ;)

Full trace:

SOLUTION

OK, it looks like in my testTestSuite.py, while executing, TextTestRunner treats "self.asserIn" lines in simpleUsageUnittest.py as self == TextTestRunner not as self == TestCase (I dont know if I explain/understand it correctly, but it is how i see it ;)). Here is fixed testTestSuite.py:

import unittest import simpleUsageUnittest import sys def suite(): testSuite = unittest.TestSuite() testSuite.addTest(simpleUsageUnittest.PythonOrgSearch('test_001_search_in_python_org')) testSuite.addTest(simpleUsageUnittest.PythonOrgSearch('test_002_goole_and_stack_test_test')) return testSuite if __name__ == "__main__": result = unittest.TextTestRunner(verbosity=2).run(suite()) sys.exit(not result.wasSuccessful()) 

'setUp' and 'tearDown' are missing because they are called automatically after every 'test'.
