私が今書いている Rails 3.2.13 アプリには、 というモデルがありBusinessます。このモデルはどんどん肥大化していったので、2 つに分割して、可用性に関連するすべてのコードを という名前の Rails の問題に抽出し、次Availabilityの場所に保存することにしました。models/concerns/business

class Business
  module Availability
    extend ActiveSupport::Concern

    AVAILABILITY_OPEN        =  1
    AVAILABILITY_CLOSED      = -1
    AVAILABILITY_COMPLETE    = -2

...

Rails ではデフォルトで懸念事項が有効になっていないため、懸念事項config/application.rbを自動ロードするために次の行を追加しました。

config.autoload_paths += %W(#{config.root}/app/models/concerns)

問題は、分割後、すべてのテストが機能しなくなり、NameError: uninitialized constant Availabilityエラーが返されることです。テストで何らかの形でこの懸念を要求する必要があると思いますが、まだそれを行うことができず、それを使用しないテストでもこの懸念が必要な理由もわかりません。

以下は、テストの実行後に返されるスタック トレースです。

更新 2

テストの実行時に発生するエラーは、フィクスチャが原因のようです。fixtures :allローディングをコメントしてtest_helper.rbtrue をアサートするだけの簡単なテストを作成すると、このテストはパスしますが、フィクスチャがロードされるとパスしません。

最後に、すべてのテストがエラーで失敗した理由を見つけました。の代わりに を使用して、Availability懸念事項で宣言された定数を参照していました。また、私のテストは現在のコードと同期していなかったため、バグを見つけるのが必要以上に困難になりました。への参照をすべて置き換えると、問題は解決しました。ここでの教訓は、アプリケーションとテスト コードを常に同期させておくことです。Availabiliy::Business::AvailabilityBusiness

特定のモデル名で試してみてください.. User::Confirmation のように

# -*- encoding : utf-8 -*-
require 'active_support/concern'

module Business::Availability
  extend ActiveSupport::Concern

この：

config.autoload_paths += Rails.root.join("app", "models", "concerns")

フィクスチャである問題の原因を特定しました。fixtures :allのメソッドを使用していましたtest_helper.rb。customers.ymlフィクスチャを実行するだけに変更するcustomer_test.rbと、エラーなしで実行できます。問題のあるフィクスチャが何であるか（businesses.ymlおそらく関連するフィクスチャであると思いますが、チェックしていません）、問題を引き起こしている理由はまだわかりません。
