QUESTION 3 We are trying to test a function called validateEmail. The purpose of the function is to take an email address as a string, and either return a tuple of the local part and domain of the meail, or raise an exception if the input is not a properly formatted emil address. For example, validateEmail('bill@microsoft.com') would return ('bill', microsoft.com'). Calling, however, validateEmail('bill') would raise a NotValidEmail error. What would the proper syntax be for testing that the validateEmail function raises an exception on invalid input? self.assertEquals(validateEmail, NotValidEmail, "bill") self.assertRaises(validateEmail, NotValidEmail, "bill") self.assertRaises(NotValidEmail, validateEmail, "bill") O self.assertEquals(NotValidEmail, validateEmail, "bill")
