我的user.rb文件

# == Schema Information
#
# Table name: users
#
#  id         :integer          not null, primary key
#  name       :string(255)
#  email      :string(255)
#  created_at :datetime         not null
#  updated_at :datetime         not null
#

class User < ActiveRecord::Base
  attr_accessible :name, :email,

 validates :name, presence: true, length: { maximum: 50 }
 validates :email, presence: true

end

我的user_spec.rb

# == Schema Information
#
# Table name: users
#
#  id         :integer          not null, primary key
#  name       :string(255)

require 'spec_helper'

describe User do

    before do
        @user = User.new(name: "Example User", email: "user@example.com")
end

  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 }
  end

  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_vaild }
  end
end
