Python envjasmine wrapper
=========================

This is a thin python wrapper around the envjasmine_ JavaScript
testing framework.

Installation
------------

You can install pyenvjasmine using pip_::

  pip install pyenvjasmine

Or you can grab the latest sources and install it from there::

  python setup.py install

Also, you can use it directly from the sources directory, in *development mode*
(useful if you want to contribute to the project)::

  pip install -e .

.. note::

   More about the *development mode* here:

   https://packaging.python.org/en/latest/distributing.html#working-in-development-mode


Running pyenvjasmine tests
--------------------------

To run the tests on this code here (as opposed to *your* JavaScript code you
want to test), install pyenvjasmine and then run::

    nosetests --cover-package=pyenvjasmine --cover-erase \
    --with-coverage --with-doctest $*

.. note::

   If you have installed pyenvjasmine in *development mode*, you can simply
   run::

     nosetests -c nose.cfg

   to run the tests from within the pyenvjasmine sources directory.


Run your own tests
------------------

The easiest way is to put your "specs" (JavaScript tests) into some directory
in your code, then in your python tests, add a new TestCase with just one test
that runs all your JavaScript tests.

The simplest solution is to set capture_output to False, so you see the output
from the js tests on the console. Something like this::

    import unittest
    from pyenvjasmine.runner import Runner

    class JavaScriptTests(unittest.TestCase):
        def test_my_javascript(self):
            runner = Runner(
                testdir='/path/to/my/testdir',
                configfile='relative/path/to/configfile')
            runner.run(capture_output=False)


If you want a more integrated test control, you could set capture_output to
True, then parse the test output that is returned from the run() method, with
something like this::

    import unittest
    from pyenvjasmine.runner import Runner

    class JavaScriptTests(unittest.TestCase):
        def test_my_javascript_no_output(self):
            runner = Runner(
                testdir='/path/to/my/testdir',
                configfile='relative/path/to/configfile')
            res = runner.run(capture_output=True)
            lines = res.splitlines()
            self.assertTrue('Failed: 0' in lines)
