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::

  py.test


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 pytest
    from pyenvjasmine.runner import Runner

    class TestJavaScript(object):
        def test_my_javascript(self):
            runner = Runner(
                testdir='/path/to/my/testdir',
                configfile='relative/path/to/configfile')
            success, stdout = runner.run()
            # assert on success, will be true if tests passed, False if any
            # test failed
            assert success
            # you can inspect stdout if you want to get more info, but it
            # will be printed to the console stdout anyway
            assert b'Total: 120' in stdout
