title: AttributeError: 'TextTestResult' object has no attribute 'assertIn'
body: <p>I am trying some Python with selenium, I have some defined tests in simpleUsageUnittest.py:</p>
  
  <pre><code>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')
  </code></pre>
  
  <p>Alone this set is working perfectly, but then I am trying to create some suite, testTestSuite.py:</p>
  
  <pre><code>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())
  </code></pre>
  
  <p>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 <a href="https://stackoverflow.com/questions/18000303/asserts-in-python-2-7-not-working-for-me-example-assertin">Asserts in Python 2.7 not working for me example assertIn</a> 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? ;)</p>

  <p><strong>SOLUTION</strong></p>
  
  <p>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:</p>
  
  <pre><code>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())
  </code></pre>
  
  <p>'setUp' and 'tearDown' are missing because they are called automatically after every 'test'.</p>
