IPython-Unittest
================

This extension provides testing support to IPython through cell magics.
Currently, we have three magics that transforms the cell code and
executes unittest: ``%%unittest_main``, ``%%unittest_testcase`` and
``%%unittest``; one magic to run external tests: ``%%external``; and one
associated magic to write external files with syntax highlight:
``%%write {mode}``

Additionally, it includes actions to Jupyter toolbar with a timer and a
people log to support coding dojo sessions. These actions can be either
loaded on demand or installed as a nbextension

How to Install
--------------

``pip install ipython_unittest``

To load the extension, please run:

.. code:: python

    %load_ext ipython_unittest

Alternatively, to load the extension and the coding dojo toolbar, please
run:

.. code:: python

    %load_ext ipython_unittest.dojo

The coding dojo toolbar can be installed as a stand-alone nbextension as
well:

::

    jupyter nbextension install --py ipython_unittest --user
    jupyter nbextension enable --py ipython_unittest --user

Cell Magics
-----------

The first magic is ``%%unittest_main``. This magic runs testcases
defined in a cell

.. code:: python

    %%unittest_main
    class MyTest(unittest.TestCase):
        def test_1_plus_1_equals_2(self):
            sum = 1 + 1
            self.assertEqual(sum, 2)

        def test_2_plus_2_equals_4(self):
            self.assertEqual(2 + 2, 4)

The second magic is ``%%unittest_testcase``. This magic creates a
testcase with functions defined in the cell and execute it.

.. code:: python

    %%unittest_testcase
    def test_1_plus_1_equals_2(self):
        sum = 1 + 1
        self.assertEqual(sum, 2)

    def test_2_plus_2_equals_4(self):
        self.assertEqual(2 + 2, 4)

The third magic is ``%%unittest``. This magic converts Python assert
into unittest functions.

.. code:: python

    %%unittest
    "1 plus 1 equals 2"
    sum = 1 + 1
    assert sum == 2
    "2 plus 2 equals 4"
    assert 2 + 2 == 4

By default, docstring in this magic will separate unittest methods.
However, if docstrings are not provided, the magic will create a method
for for each assert.

These magics support optional arguments:

::

    -c (--color):      change logo color to indicate whether or not the tests
                       have passed
    -p (--previous) P: set cursor to P cells before (default: -1 = next cell)
    -s (--stream) S:   set test output stream (default: 'sys.stdout')
    -t (--testcase) T: define TestCase name.
                       Valid for '%%unittest' and '%%unittest_testcase'
    -u (--unparse):    print cell source code after transformations.

The fourth magic is ``%%external``. This magic runs external system
commands and check their exit codes. This way, it is possible to run
tests from other languages:

.. code:: python

    %%external --previous 1
    mocha test.js

The ``%external`` magic supports the arguments ``--color`` and
``--previous`` described before.

Finally, since it is possible to run external commands, we included an
extra magic, ``%%write`` to write files and keep the syntax highlight.
This magic receives a CodeMirror mode as first argument and the
remaining arguments are redirected to IPython's ``%%writefile``

Note that it will start highlighting after the first execution.

.. code:: javascript

    %%write javascript test.js
    var assert = require('assert');
    describe('Array', function() {
      describe('#indexOf()', function() {
        it('should return -1 when the value is not present', function() {
          assert.equal(-1, [1,2,3].indexOf(4));
        });
      });
    });
