テスト作成
以下が、Userモデルに対するすテスト（RSpec）
spec/models/user_spec.rb
require'rails_helper'RSpec.describeUser,type: :modeldobeforedo@user=User.create(name: "Yamada Taro",user_id: "taro",email: "taro@example.com",)end# name、user_id、emailがあれば有効な状態であることit"is valid with a name, user_id, email"douser=User.new(name: "Sato Taro",user_id: "sato",email: "sato@example.com",)expect(user).tobe_validend# nameがなければ無効な状態であること（nameは必須項目）it"is invalid without a name"douser=User.new(name: nil)user.valid?expect(user.errors[:name]).toinclude("can't be blank")end# メールアドレスがなければ無効な状態であること（emailは必須項目）it"is invalid without an email address"douser=User.new(email: nil)user.valid?expect(user.errors[:email]).toinclude("can't be blank")end# 重複したメールアドレスなら無効な状態であることit"is invalid with a duplicate email address"douser=User.new(email: "taro@example.com")user.valid?expect(user.errors[:email]).toinclude("has already been taken")end# メールアドレスが小文字化されていることit"email addresses should be saved as lower-case"domixed_case_email="TANAKA@example.com"@user.email=mixed_case_email@user.saveexpect(@user[:email]).toeq("tanaka@example.com")end# メールアドレスの一意性の検証it"email is unique"douser=User.create(name: "Test",user_id: "test",email: "taro@example.com")expect(user).to_notbe_validexpect(user.errors[:email]).toinclude("has already been taken")end# メールアドレスのフォーマットの検証describe"mail"docontext"Correct format"doit"is OK"do@user.email='user@example.com'expect(@user).tobe_validendendcontext"Incorrect format"doit"is NG"do@user.email='user@example,com'expect(@user).to_notbe_validexpect(@user.errors[:email]).toinclude("is invalid")endendend# nameの長さの検証describe"name length"docontext"length 50 txt"doit"is OK"do@user.name='a'*50expect(@user).tobe_validendendcontext"length 51 txt"doit"is NG"do@user.name='a'*51expect(@user).to_notbe_validexpect(@user.errors[:name]).toinclude("is too long (maximum is 50 characters)")endendendend
it"is invalid without a name"douser=User.new(name: nil)user.valid?expect(user.errors[:name]).toinclude("can't be blank")end
メールアドレスがなければ無効な状態であること（emailは必須項目）
spec/models/user_spec.rb
it"is invalid without an email address"douser=User.new(email: nil)user.valid?expect(user.errors[:email]).toinclude("can't be blank")end
valid? が false なら、errors.messagesにエラー内容が格納されます。今回は、それが、"can't be blank"であることを期待しています。
重複したメールアドレスなら無効な状態であること
spec/models/user_spec.rb
it"is invalid with a duplicate email address"douser=User.new(email: "taro@example.com")user.valid?expect(user.errors[:email]).toinclude("has already been taken")end
valid? が false なら、errors.messagesにエラー内容が格納されます。今回は、それが、"has already been taken"であることを期待しています。
メールアドレスが小文字化されていること
spec/models/user_spec.rb
it"email addresses should be saved as lower-case"domixed_case_email="TANAKA@example.com"@user.email=mixed_case_email@user.saveexpect(@user[:email]).toeq("tanaka@example.com")end
it"email is unique"douser=User.create(name: "Test",user_id: "test",email: "taro@example.com")expect(user).to_notbe_validexpect(user.errors[:email]).toinclude("has already been taken")end
taro@example.comはすでに保存されたアドレスなので、バリデーションは通らないことと、エラーメッセージは"has already been taken"であることを期待しています。
