RSpec

Everyday Rails Testing with RSpec sample application (2022 Japanese edition)

Sample Rails application for Everyday Rails Testing with RSpec: A Practical Approach to Test-driven Development by Aaron Sumner. This repository is the official fork for the 2022 Japanese edition.

このリポジトリのRailsアプリは「 Everyday Rails - RSpecによるRailsテスト入門 」のサンプルアプリケーションです。

2022年更新の日本語版より、 原著のソースコード をフォークし、日本語版独自にメンテナンスしていくことになりました。

cover image

このリポジトリでは既存のアプリケーションに対して、少しずつテストを追加していく過程を説明します。最初はまったくテストのないコードベースから始まり、 モデルスペック、コントローラスペック、システムスペック、リクエストスペックと順に進みます。

このリポジトリの各ブランチを開くと、各章で追加したコードが確認できます。詳しくは本書の第1章をご覧ください。

Gitを使うとブランチ名を指定して各バージョンをチェックアウトできます。詳しくは本書をご覧ください。

Gitが苦手な方は、GitHubの便利な ブランチ機能を利用してください。 フィルターで特定のブランチを選択し、オンラインでソースコードをブラウズすることができます。

Gitについてもっと詳しく知りたい方は、無料で公開されている「 Git Immersion 」または「 Try Git 」（いずれも英語版）がお勧めです。

everydayrails-rspec-jp-2022's Issues

9章内のfocusタグの付いたexampleのみをテストする設定について

9章の「速くテストを書き、速いテストを書く」で学んだことがありましたのでお知らせします。

focusタグの付いたexampleのみをテストする設定をしたいと思い、PDF版の175ページ一番上のコードspec/spec_helper.rbを見ながら、

image

該当のファイルを開いてみましたところ、下記のスクショのように1行で設定されたコードがありました(下線部分)。
このコメントアウトを外して実行してみたら、focusタグの付いたexampleのみのテストができました。

image

スクール内の学習中だったためメンターさんに伺ったところ、 filter_run_when_matching は 3.5 で追加されたオプションで config.filter_run と config.run_all_when_everything_filtered を両方設定してくれるとのことでした。
https://github.com/rspec/rspec-core/blob/main/Changelog.md#350beta3--2016-04-02

確認のため、書籍のP175と同じように設定しても、focusタグの付いたexampleのみをテストすることができました。
修正が必要かどうかの判断はつかなかったのですが、お知らせのみさせていただきます。

ご確認をよろしくお願いします🙇🏻‍♀️

11章内のサンプルコードspec/system/projects_spec.rbにlogin_asヘルパーが残っている

本書の変更履歴の239ページ(PDF版)で下記のように書かれていました。

第11章
• Warden が提供しているlogin_as ヘルパーを、Devise が提供しているsign_in ヘルパー
に変更。

203ページのspec/system/projects_spec.rbではsign_in ヘルパーを使ったsign_in userに変更されていますが、
206ページと213ページの同ファイルの同部分はlogin_as user, scope: :userのままのようです。

お手数ですがご確認いただけますと幸いです。よろしくお願いします🙇🏻‍♀️

スクショを添付いたします。

  • 203ページ・・・sign_in ヘルパーに変更できている
    image

  • 206ページ・・・login_as ヘルパーのまま

  • 213ページ・・・login_as ヘルパーのまま

`bin/setup` を実行すると、`db/schema.rb` が更新される

概要

git clone 後、main ブランチで bin/setup を実行すると db/schema.rb が更新され、以下のような差分が発生しました

urimaro/everydayrails-rspec-jp-2022@a87355f

このまま進めることはできますが、気になったので報告いたしました
私の環境の問題でしょうか？

再現手順

git clone https://github.com/JunichiIto/everydayrails-rspec-jp-2022.git
cd everydayrails-rspec-jp-2022
bin/setup

環境

  • Ruby 3.1.0
  • Rails 7.0.2.3

7章リクエストスペックでAPIをテスト - GETリクエストをテストするでも記述ミスについて

概要

たいしたミスではないのですが😅、コードではなく本書の方でタイポを発見したので報告します。
7章「リクエストスペックでAPIをテスト」の「GETリクエストをテストする」で見てみましょうが見てましょうとなっています。（スクリーンショット参考）

該当箇所のスクリーンショット

ご確認ください🙇‍♂️

Better Specsの日本語翻訳ページについて

[Rails のテストに関するさらなる情報源]->[Better Specs]の説明に
[訳注: Better Specs には日本の翻訳ページもあります]とありますが、見当たりませんでした。
現在も存在しますか？（検索不足でしたらすみません・・・）

2014, 2015年頃の記事には以下のURLが登場しますが、現在404です。
https://www.betterspecs.org/jp/

8章スペックをDRYに保つ、カスタムマッチャ内の記述について

こんにちは。コードの内容ではありませんが、本書の記述についてタイポかなと思うところがありましたのでお知らせします。
PDF版だと147ページ、第8章スペックをDRYに保つ、カスタムマッチャ内で「期待しまします。」が「期待します。」だと思いました。
スクリーンショットを添付します。よろしくお願いします🙏

5章「コントローラースペック - ユーザー入力をテストする」サンプルコードの修正

以下のFactoryのサンプルコードは中括弧({})が必要ではないかと思い、Issueとして登録しました。
報告する場所として適切でなかったり、思い違いがありましたらご指摘いただけますと幸いです🙇🏻‍♂️

# spec/factories/projects.rb
FactoryBot.define do
  ...

  trailt :invalid do
-   name nil
+   name { nil }
  end
end

参考：
修正前の状態でのエラーメッセージ

  1) ProjectsController#create as an authenticated user with invalid attributes does not add a project
     Failure/Error: project_params = FactoryBot.attributes_for(:project, :invalid)
     
     KeyError:
       Trait not registered: "name" referenced within "invalid" definition
     # ./spec/controllers/projects_controller_spec.rb:81:in `block (5 levels) in <top (required)>'
     # ------------------
     # --- Caused by: ---

     #   Trait not registered: "name" referenced within "invalid" definition
     #   ./spec/controllers/projects_controller_spec.rb:81:in `block (5 levels) in <top (required)>'

ご確認よろしくお願いいたします🙏

11章「テスト駆動開発に向けて - 外から中へ進む」サンプルコードの訂正

節の最後に載っているapp/controllers/projects_controller.rbのサンプルコード内でupdate_attributesを使用していますが、Rails 6.1で削除済みのメソッドのため、正しくはupdateではないかと思いました。
以下の画像の赤線の部分です。

スクリーンショット 2022-01-28 15 45 12

GitHub上のサンプルコードの方はupdateになっていました。

everydayrails-rspec-jp-2022/app/controllers/projects_controller.rb

Lines 61 to 65 in 1340db6

def complete
if @project.update(completed: true)
redirect_to @project,
notice: "Congratulations, this project is complete!"
else

ご確認いただけますと幸いです 🙏

`bundle exec rspec` を実行すると `ActiveRecord::EnvironmentMismatchError` が発生する

概要

bundle exec rspec を実行すると ActiveRecord::EnvironmentMismatchError が発生します
だだし、specは最後まで実行されます

再現手順

書籍の以下の説明に従ってセットアップすると再現します

    1. イントロダクション - サンプルアプリケーションのセットアップ手順

具体的なコマンドは以下のとおりです

git clone https://github.com/JunichiIto/everydayrails-rspec-jp-2022.git
cd everydayrails-rspec-jp-2022
rbenv local 3.1.0
bin/setup
bundle exec rspec

SSHではなくHTTPSを使っていますが、特別な理由はありません

実際の挙動

実行時のログを添付します(※)

※ issueに貼り付けると期待した通りに改行されなかったので…

回避方法

メッセージ通り、以下のコマンドを実行すると、エラーが発生しなくなります

bin/rails db:environment:set RAILS_ENV=test

環境

  • Ruby 3.1.0
  • Rails 7.0.4
  • mainブランチ

その他

以下のissueと同じ現象だと思うのですが、すでに対策はmergeされているようなので、なぜ発生するのかよくわかっていません

Railsをアップグレードすると発生する可能性があるのかもしれないですね…
完全に推測です

クローン直後のセットアップ後に rspec が落ちてしまう

はじめまして

電子書籍を購入後、環境セットアップして bundle exec rspec を main ブランチで実行しましたが落ちてしまいました。

ご確認頂けますでしょうか？

11章本文の記述ミスについて

11章「テスト駆動開発に向けて」の「レッドからグリーンへ」における「RSpecは次に何を…」で始まる段落内で記述ミスと思しき箇所を発見したので報告します。自分の勘違いであればご容赦ください🙏

以下のcomplete?は、正しくはcompleted?ではないでしょうか？

スクリーンショット

以下はmobi版をKindle for PCで開いたスクショですが、念の為PDF版など他バージョンでも同様の記述ミスを確認しております〜

長谷川雅士さんの_Kindle_for_Mac_3_-_Everyday_Rails_-_RSpecによるRailsテスト入門

"Active Job" と思われる文言が "Action Job" になっている

PDFのP192「10. その他のテスト - メール送信をテストする」の3行目(コードブロックは除く)において、以下のように記載されています

このメソッドはAction Jobが UserMailer.welcome_email に提供してくれるメソッドです。

Action Job の部分は、正しくは Active job なのではないかと思いました。
