Writing Tests for Allura Tools
==============================

Testing the controllers and models of an Allura tool is fairly
straightforward.  Generally, you should follow the example of tests in the
`allura/tests/functional` directory for controller tests and
`allura.tests.model` for model tests.  For functional tests, the Allura platform
provides a convenient "test harness" :class:`allura.controllers.test.TestController` controller
class which is used as the application root for the
:class:`allura.tests.TestController` class.

In order to test your new tool controllers, you simply need to use the `self.app.get()`
and `self.app.post()` methods of your test controller.  The test harness makes
all the tools available in the system available under the URL /*entry point
name*/.  So to test the :mod:`allura.ext.project_home` tool, for instance, we
need only write the following::

    from allura.tests import TestController

    class TestProjectHome(TestController):

        def test_home(self):
            r = self.app.get('/home/')

Whenever you use the :class:`allura.tests.TestController` app property, the
test harness sets up the context so that `c.project` is always the
`projects/test` project and whichever tool name you request is mounted at its
entry point (so the Wiki tool will be mounted at /Wiki/).  `c.user` is always
set to the `test-admin` user to avoid authentication issues.

The framework used to generate the WSGI environment for testing your tools is
provided by the `WebTest <http://pythonpaste.org/webtest/>`_ module, where you can
find further documentation for the `.get()` and `.post()` methods.

Testing Allura models is also straightforward, though you will often
need to setup global objects before your test. If the code under test
uses globals (like `g` and `c`), but your test doesn't require the
fully-loaded wsgi app, you can do something like this:

.. code-block:: python

    from tg import tmpl_context as c

    from alluratest.controller import setup_unit_test
    from allura.lib import helpers a h
    from allura import model as M

    def setup_method(self, method):
        # set up globals
        setup_unit_test()

        # set c.project and c.app
        h.set_context('test', 'wiki', neighborhood='Projects'):
        c.user = M.User.query.get(username='test-admin')

Testing the tasks and events is  similar to testing models.  Generally, you will
simply want to call your `@task` and `@event_handler` methods directly rather
than setting up a full mocking infrastructure, though it is possible to use the
MonQTask model in the allura model if you wish to do more functional/integration testing.
