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

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

.. _envjasmine : https://github.com/trevmex/EnvJasmine


Running the tests of this python module:
----------------------------------------

To run the tests on this code here (as opposed to *your* JavaScript
code you want to test), install this into a virtualenv, install
nose and maybe coverage in that virtualenv and then run::

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


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 TestRunner

    class JavaScriptTests(unittest.TestCase):
        def test_my_javascript(self):
            runner = TestRunner(
                      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::

        def test_my_javascript_no_output(self):
            runner = TestRunner(
                      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)
