+"""Test for Video Xmodule functional logic.
+These tests data readed from xml, not from mongo.
+
+We have a ModuleStoreTestCase class defined in
+common/lib/xmodule/xmodule/modulestore/tests/django_utils.py.
+You can search for usages of this in the cms and lms tests for examples.
+You use this so that it will do things like point the modulestore
+setting to mongo, flush the contentstore before and after, load the
+templates, etc.
+You can then use the CourseFactory and XModuleItemFactory as defined in
+common/lib/xmodule/xmodule/modulestore/tests/factories.py to create the
+course, section, subsection, unit, etc.
