# The main methods that we make use of in unit testing for Python are:
#
# assert: base assert allowing you to write your own assertions
# assertEqual(a, b): check a and b are equal
# assertNotEqual(a, b): check a and b are not equal
# assertIn(a, b): check that a is in the item b
# assertNotIn(a, b): check that a is not in the item b
# assertFalse(a): check that the value of a is False
# assertTrue(a): check the value of a is True
# assertIsInstance(a, TYPE): check that a is of type "TYPE"
# assertRaises(ERROR, a, args): check that when a is called with args that it raises ERROR
#
# There are more methods available to us, which you can view - see
# https://docs.python.org/2/library/unittest.html
