-# The Engines testing extensions enable developers to load fixtures into specific
-# tables irrespective of the name of the fixtures file. This work is heavily based on
-# patches made by Duane Johnson (canadaduane), viewable at
-# http://dev.rubyonrails.org/ticket/1911
-#
-# Engine developers should supply fixture files in the <engine>/test/fixtures directory
-# as normal. Within their tests, they should load the fixtures using the 'fixture' command
-# (rather than the normal 'fixtures' command). For example:
-#
-# class UserTest < Test::Unit::TestCase
-# fixture :users, :table_name => LoginEngine.config(:user_table), :class_name => "User"
-#
-# ...
-#
-# This will ensure that the fixtures/users.yml file will get loaded into the correct
-# table, and will use the correct model object class.
-
-
-
-# A FixtureGroup is a set of fixtures identified by a name. Normally, this is the name of the
-# corresponding fixture filename. For example, when you declare the use of fixtures in a
-# TestUnit class, like so:
-# fixtures :users
-# you are creating a FixtureGroup whose name is 'users', and whose defaults are set such that the
-# +class_name+, +file_name+ and +table_name+ are guessed from the FixtureGroup's name.
