Test for scripts
================

This test suite tests various python scripts. Ultimately these tests should be
doctests provided directly in the implementation (as utilities for example).

Tests for returnNone.py
-----------------------

This should be self-explanatory:

  >>> self.portal.returnNone() is None
  True

Tests for reverseList.py
------------------------

Test with a list:

  >>> self.portal.reverseList([1, 2, 3])
  [3, 2, 1]

Test with a dict:

  >>> self.portal.reverseList((1, 2, 3))
  [3, 2, 1]

Tests for unique.py
-------------------

Test a list of numbers which contains duplicates:

  >>> self.portal.unique([1,2,3,1,2,3])
  [1, 2, 3]

Test a string sequence:

  >>> self.portal.unique('abcabc')
  ['a', 'c', 'b']

And finally a tuple of lists:

  >>> self.portal.unique(([1, 2], [2, 3], [1, 2]))
  [[1, 2], [2, 3]]
