この記事でやること

今回は

モデルの単体テストの実装
バグ潰し(モデルのバリデーション定義)

をしていきたいと思います。

予めお断りしておきたいのですが、
独学なのでこれで動くテストはできても正しい実装になっているかはわからないです。
申し訳ないです。

方針

方針としては
ユーザーデータに特定の値をセットし、user.valid実行時の戻り値を見る
trueであってほしいもの（正常系）はassert
falseであってほしいもの（異常系）はassert_notで判定していこうかと思います。

テストを作る

user_test.rbは上記の方針でこうなりました。

require 'test_helper'

class UserTest < ActiveSupport::TestCase
  def setup
    @user = User.new(
      login_id: "hoge",
      display_name: "hoge",
      password:"hogehoge",
      password_confirmation: "hogehoge",
      email: "hoge@email.com",
      authority_flag: "0"
    )
  end

    #login_id(異常系)
    #重複する2ユーザー
    test "check login_id is duplicate invalid" do
      @user.login_id = "test"
      assert_not @user.valid?,"login_id can't duplicated"
    end

    #記号を含む
    test "check login_id include symbol invalid" do
      @user.login_id = "test@"
      assert_not @user.valid?,"login_id can't include symbols"
    end

    #全角文字を含む
    test "check login_id include wide charactor invalid" do
      @user.login_id = "テスト"
      assert_not @user.valid?,"login_id can't include wide charactors"
    end

    #nil
    test "check login_id is nil invalid" do
      @user.login_id = ""
      assert_not @user.valid?,"login_id is not nil"
    end

    #3文字
    test "check login_id is too short invalid" do
      @user.login_id = "foo"
      assert_not @user.valid?,"login_id is more than 4 charactors"
    end

    #21文字
    test "check login_id is too long invalid" do
      @user.login_id = "abcdeabcdeabcdeabcdea"
      assert_not @user.valid?,"login_id is less than 20 charactors"
    end

    #display_name(異常系)
    #nil
    test "check display_name is nil invalid" do
      @user.display_name = ""
      assert_not @user.valid?,"display_name is not nil"
    end

    #21文字
    test "check display_name is too long invalid" do
      @user.display_name = "21文字の名前の長いユーザー名にしています"
      assert_not @user.valid?,"display_name is less than 20 charactors"
    end

    #password(正常系)
    #記号を含む
    test "check password include symbol invalid" do
      @user.password = "test/"
      @user.password_confirmation = "test/"
      assert_not @user.valid?,"password can't include symbols"
    end
    #全角文字を含む
    test "check password include wide charactor invalid" do
      @user.password = "パスワード"
      @user.password_confirmation = "パスワード"
      assert_not @user.valid?,"password can't include wide charactors"
    end
    #nil
    test "check password is nil invalid" do
      @user.password = ""
      @user.password_confirmation = ""
      assert_not @user.valid?,"password is not nil"
    end
    #3文字

      @user.password = "foo"
      @user.password_confirmation = "foo"

      @user.password_confirmation = "testtesttesttesttesta"

      assert_not @user.valid?,"email must be unique"

すっごい長いですが、単体試験はこんなもんかと。

minitest-reportersの設定

test_helperを編集して以下のようにします。

ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'
require "minitest/reporters"
Minitest::Reporters.use!

class ActiveSupport::TestCase
  # Setup all fixtures in test/fixtures/*.yml for all tests
  # in alphabetical order.
  fixtures :all

  # Add more helper methods to be used by all tests here...
end

ENV['RAILS_ENV'] ||= 'test'

require File.expand_path('../../config/environment', __FILE__)

require 'rails/test_help'

require "minitest/reporters"

Minitest::Reporters.use!

class ActiveSupport::TestCase

# Setup all fixtures in test/fixtures/*.yml for all tests

# in alphabetical order.

fixtures :all

# Add more helper methods to be used by all tests here...

end

使い方はRailsチュートリアルにも書いていますが。
公式のgithubにも書いています。

テストを実行

今回テストするのはユーザーモデルだけに絞るのでこんな感じでコマンド実行

＄ rails test test/models/user_test.rb

1	＄ rails test test/models/user_test.rb

minitest-reportersを導入するとこうしてカラーで出てきます。
とても見やすくなります。

で、正常系3項目、パスワードのnilチェック以外はまだ試験に失敗した状態です。

残り19項目の試験を通るようにモデルを定義していきます。

モデルを定義する

class User < ApplicationRecord
  has_secure_password
end

class User < ApplicationRecord

has_secure_password

end

bcryptを使用するためにhas_secure_passwordだけは書いてました。
他の定義もしていきます。

class User < ApplicationRecord
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  VALID_HALF_CHARACTER_REGEX = /\A[a-zA-Z0-9]+\z/i
  has_secure_password
