active_decoratorがtest_unitでもrspecと同じくそのままじゃhelperを使ったdecoratorのtestが書けないんだけど下記のようにすれば動く。（active_decoratorのREADMEに書いてあるdecoratorのテストの例）

# test/test_helper.rb:
class ActiveSupport::TestCase
  include ActionView::TestCase::Behavior
end

# test/decorators/user_decorater_test.rb:
require 'test_helper'

class UserDecoratorTest < ActiveSupport::TestCase
  def setup
    ActiveDecorator::ViewContext.current = controller.view_context
    @user = ActiveDecorator::Decorator.instance.decorate users(:jean)
  end 

  test 'full_name' do
    assert_equal 'Jean Valjean', @user.full_name
  end

  test 'link' do
    assert_equal '<a href="http://jeanvaljean.com">Jean Valjean</a>', @user.link
  end
end

$ rake test test/decorators/user_decorator_test.rb
Run options: --seed 37850
