RailsプロジェクトにRSpecを導入(ほぼ最小構成)

Posted at

Gemfileに記述


rspecとテストデータ生成に使うfactory_girlを導入
ほぼ最小構成。

Gemfile
group :development, :test do
  gem 'rspec-rails', '~> 3.5'
  gem "factory_girl_rails"
end

RSpec初期化


インストールコマンドを打って初期化、ヘルパーを生成します。

$ bundle exec rails generate rspec:install

result
      create  .rspec
       exist  spec
      create  spec/spec_helper.rb
      create  spec/rails_helper.rb

使ってみる


$ rspec spec/*

コラム


結果出力の設定

.rspecに --color を追加しておく
テストの成否を緑/赤で表示するようになり、赤(失敗時)のみ詳細を出すようになる
