Michael Hartl のチュートリアルに従って、RoR 4 アプリケーションを開発しています。
ユーザー認証テストを実装すると、すべてがうまくいきます。本よりも必須フィールドがいくつかあります。モデルは次のとおりです。
class User < ActiveRecord::Base
before_save { self.email = email.downcase }
VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
validates :playground_id, presence: true
validates :default_playground_id, presence: true
validates :active_from, presence: true
validates :active_to, presence: true
validates :last_name, presence: true, length: { maximum: 100 }
validates :login, presence: true, uniqueness: true, length: { maximum: 30 }
validates :email, presence: true, uniqueness: true, length: { maximum: 100 }, format: { with: VALID_EMAIL_REGEX }
validates :directory_id, length: { maximum: 100 }
validates :first_name, length: { maximum: 100 }
validates :password_digest, length: { maximum: 100 }
validates :remember_token, length: { maximum: 100 }
validates :created_by, length: { maximum: 30 }
validates :updated_by, length: { maximum: 30 }
has_secure_password
end
認証プロセスのみに関連するテストは次のとおりです。
###USER6 to test that password is correctly managed
describe "when password is not present" do
before do
@user = User.new(playground_id: 0, default_playground_id: 0, last_name: "Other User", login: "OTHER_USR",
email: "other@example.com", active_from: "2013-01-01", active_to: "2113-01-01", is_admin: 1.zero?,
password: " ", password_confirmation: " ")
end
it { should_not be_valid }
end
describe "when password doesn't match confirmation" do
before { @user.password_confirmation = "mismatch" }
it { should_not be_valid }
end
describe "with a password that's too short" do
before { @user.password = @user.password_confirmation = "a" * 5 }
it { should be_invalid }
end
describe "return value of authenticate method" do
before { @user.save }
let(:found_user) { User.find_by(email: @user.email) }
describe "with valid password" do
it { should eq found_user.authenticate(@user.password) }
end
describe "with invalid password" do
let(:user_for_invalid_password) { found_user.authenticate("invalid") }
it { should_not eq user_for_invalid_password }
specify { expect(user_for_invalid_password).to be_false }
end
end
### end
はい、うまくいきます!テストを実行した結果は次のとおりです。
Failures:
1) User model validation: with a password that's too short should be invalid
Failure/Error: it { should be_invalid }
expected invalid? to return true, got false
# ./spec/models/user_spec.rb:171:in `block (3 levels) in <top (required)>'
Finished in 0.28647 seconds
37 examples, 1 failure
Failed examples:
rspec ./spec/models/user_spec.rb:171 # User model validation: with a password that's too short should be invalid
Randomized with seed 18843
ここで、User モデルにパスワードの長さの検証を追加すると、次のようになります。
...
validates :created_by, length: { maximum: 30 }
validates :updated_by, length: { maximum: 30 }
has_secure_password
validates :password, length: { minimum: 6 }
end
テストを実行すると、未定義の認証方法に関するエラーが返され、認証に関係のないテストにもブレーキがかかります。
...
5) User model validation: return value of authenticate method with invalid password
Failure/Error: let(:user_for_invalid_password) { found_user.authenticate("invalid") }
NoMethodError:
undefined method `authenticate' for nil:NilClass
# ./spec/models/user_spec.rb:183:in `block (4 levels) in <top (required)>'
# ./spec/models/user_spec.rb:186:in `block (4 levels) in <top (required)>'
Finished in 0.29266 seconds
37 examples, 5 failures
Failed examples:
rspec ./spec/models/user_spec.rb:51 # User model validation: availability of mandatory fields should be valid
rspec ./spec/models/user_spec.rb:135 # User model validation: when email format is valid should be valid
rspec ./spec/models/user_spec.rb:179 # User model validation: return value of authenticate method with valid password
...
これの理由は何ですか、どうすれば解決できますか?
ご協力いただきありがとうございます、
