Testing the doctest extension
=============================

Simple doctest blocks
---------------------

>>> 1+1
2
>>> 1/0
Traceback (most recent call last):
  ...
ZeroDivisionError: integer division or modulo by zero


Special directives
------------------

* doctest

  .. doctest::

     >>> 1+1
     2
     >>> 1/0
     Traceback (most recent call last):
       ...
     ZeroDivisionError: integer division or modulo by zero

* testcode/testoutput

  .. testcode::

     print(1+1)

  .. testoutput::

     2

  .. testcode::

     1/0

  .. testoutput::

     Traceback (most recent call last):
       ...
     ZeroDivisionError: integer division or modulo by zero

* testsetup

  .. testsetup:: *

     def squared(x):
     	return x * x

  .. doctest::

     >>> squared(2)
     4

  .. testcode::

     print(squared(2))

  .. testoutput::

     4

  >>> squared(2)
  4

* options for doctest/testcode/testoutput blocks

  .. testcode::
     :hide:

     print('Output         text.')

  .. testoutput::
     :hide:
     :options: +NORMALIZE_WHITESPACE

     Output text.

  .. doctest::
     :pyversion: >= 2.0

     >>> a = 3
     >>> a
     3

  .. doctest::
     :pyversion: < 2.0

     >>> a = 3
     >>> a
     4

* grouping

  .. testsetup:: group1

     def add(x, y):
         return x + y


  ``add`` is now known in "group1", but not in others.

  .. doctest:: group1

     >>> add(1, 1)
     2

  .. doctest:: group2

     >>> add(1, 1)
     Traceback (most recent call last):
       ...
     NameError: name 'add' is not defined

  Interleaving testcode/testoutput:

  .. testcode:: group1

     print(squared(3))

  .. testcode:: group2

     print(squared(4))

  .. testoutput:: group1

     9

  .. testoutput:: group2

     16


.. testcleanup:: *

   import test_ext_doctest
   test_ext_doctest.cleanup_call()

non-ASCII result
----------------

>>> print('umlauts: äöü.')
umlauts: äöü.
>>> print('Japanese: 日本語')
Japanese: 日本語

keep control char in raw string
-------------------------------

.. doctest::

    >>> print('one\ntwo')
    one
    two
    >>> print(r'one\ntwo')
    one\ntwo
