Shoulda-machersを使うと素晴らしく簡潔かつ直感的にテストをかけるようになるので導入してみることに。しかしインストールして試してみたはいいものの、どうにもこうにも NoMethodError: undefined method `validate_numericality_of' などとあらゆるメソッドが無いよ、とエラーが吐かれハマったのでメモ。パーフェクトRuby on Railsのサンプルコードでハマった方は特におすすめ。 環境 Rails 4.2.6 rspec-rails 3.4.2 shoulda-matchers 3.1.1 導入方法 1. Gemfileにrspec-railsとshoulda-matchersを追加 # /Gemfile # development・test環境双方でrspec-railsが必要 group :development, :test
