+Test pyloader's Factory
+=======================
+
+Boilerplate::
+
+    >>> import os
+    >>> from pyloader.factory import PyFactory
+
+Construct a factory::
+
+    >>> factory = PyFactory()
+
+Make a configuration::
+
+    >>> config = {'': {'path': os.path.join(here, 'objects.py:stringsort'), 'args': ['foo', 'bar']}} 
+
+Load it::
+
+    >>> factory.configure(config)
+
+Get the thing::
+
+    >>> factory.load()
+    'abfoor'
