+Testing Allura models is also straightforward, though you will often
+need to setup pylons global objects before your test. If the code under test
+uses pylons globals (like `g` and `c`), but your test doesn't require the
+fully-loaded wsgi app, you can do something like this::
 
-    import mock
-    from pylons import tmpl_context as c, app_globals as g
+    from pylons import tmpl_context as c
 
-    from allura.lib.app_globals import Globals
+    from alluratest.controller import setup_unit_test
+    from allura.lib import helpers a h
     from allura import model as M
 
     def setUp():
-        g._push_object(Globals())
-        c._push_object(mock.Mock())
-        g.set_project('projects/test')
-        g.set_app('hello')
+        # set up pylons globals
+        setup_unit_test()
+
+        # set c.project and c.app
+        h.set_context('test', 'wiki', neighborhood='Projects'):

 Testing the tasks and events is  similar to testing models.  Generally, you will
