"uninitialized constant" when included test helper module

I am getting an uninitialized constant error when trying to include a helper module into a test.

I have the following files in my rails test directory 

functional> admin> school_controller_test.rb
functional> controller_helper.rb

The class/modules bodies are as follows:

module ControllerHelper
  def check_sort_order (items, column, direction)
    ...
  end
end

class Admin::SchoolsControllerTest < ActionController::TestCase
  include ::ControllerHelper 

  test "should sort by columns" do
    check_sort_order(assigns(:schools), 'schools.name', 'asc')
    check_sort_order(assigns(:schools), 'schools.name', 'desc')
  end
end

When I run this, the test output is:

/.../.rvm/gems/ruby-1.9.2-p0/gems/rspec-core-2.3.0/lib/rspec/core/backward_compatibility.rb:20:in `const_missing': uninitialized constant ControllerHelper (NameError)

I've tried playing with the namespaces, but can't get the module mixed in at all! Any ideas why I'm getting this error? Or is this even the correct way to extract common test functions? I'm very new to Rails, so any advice would be appreciated :)

Cheers!

For me what worked (found via trail and error) was:

require "./app/helpers/currencies_helper.rb"

Try adding this to test_helper.rb:

require "test/functional/controller_helper"

Side note: Not sure about test:unit, but rspec has a spec/support directory for files to get auto-loaded.
