帶電子郵件格式驗證失敗的rspec測試

Question

我遵循RoR教程;我堅持在電子郵件格式驗證部分。我的代碼檢查三次從書中，沒有任何遺漏或錯誤，但我得到這個錯誤：

$ bundle exec rspec spec/models/user_spec.rb 

...[deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_locales = false to avoid this message. 
....F 

Failures: 

    1) User when name is not present when email format is valid should be valid 
    Failure/Error: expect(@user).to be_valid 
     expected #<User id: nil, name: " ", email: "user@foo.COM", created_at: nil, updated_at: nil> to be valid, but got errors: Name can't be blank

規格/型號/ user_spec.rb文件：

require 'spec_helper' 

describe User do 
before { @user = User.new(name: "Example User", email: "user@example.com") } 
    subject { @user } 
    it { should respond_to(:name) } 
    it { should respond_to(:email) } 

    it { should be_valid } 
    describe "when name is not present" do 
    before { @user.name = " " } 
    it { should_not be_valid } 

describe "when email is not present" do 
    before { @user.email = " " } 
    it { should_not be_valid } 
    end 
    describe "when name is too long" do 
    before { @user.name = "a" * 51 } 
    it { should_not be_valid } 
    end 
describe "when email format is invalid" do 
    it "should be invalid" do 
     addresses = %w[user@foo,com user_at_foo.org example.user@foo. 
        foo@bar_baz.com foo@bar+baz.com] 
     addresses.each do |invalid_address| 
     @user.email = invalid_address 
     expect(@user).not_to be_valid 
end 
end 
end 
    describe "when email format is valid" do 
    it "should be valid" do 
     addresses = %w[user@foo.COM A_US-ER@f.b.org frst.lst@foo.jp a+b@baz.cn] 
     addresses.each do |valid_address| 
     @user.email = valid_address 
     expect(@user).to be_valid 
     end 
    end 
    end 
end 
end 

應用程序/模型/user.rb文件：

class User < ActiveRecord::Base 
    validates :name, presence: true, length: { maximum: 50 } 
    VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i 
    validates :email, presence: true, format: { with: VALID_EMAIL_REGEX } 
end

需要設置名稱才能使其有效。

看說明書，你寫道：

describe "when name is not present" do 
    before { @user.name = " " } 
    it { should_not be_valid } 
end 

所以，如果你希望你的電子郵件測試通過，你需要確保一個名稱預先設定。
