【问题描述】：

问题是我预计第二次 it 会失败，第三次会通过，但情况恰恰相反。 2通过，3失败。有人知道为什么吗？

spec/models/user_spec.rb

require 'spec_helper'

describe User do
  it 'has a valid factory' do
    FactoryGirl.create(:user).should be_valid
  end
  it 'is invalid with empty email1' do
    # I've also tried
    # FactoryGirl.build(:user, email: nil, validation_scenario: 'create').should be_valid
    FactoryGirl.build(:user, email: nil).should be_valid
  end
  it 'is invalid with empty email2' do
    FactoryGirl.build(:user, email: nil).should_not be_valid
  end
end

spec/factories/user.rb

require 'faker'

FactoryGirl.define do
  factory :user do |u|
    u.email                 { Faker::Internet.email }
    u.password              'password'
    u.password_confirmation 'password'
  end
end

models/user.rb

class User < ActiveRecord::Base

  attr_accessor :password, :validation_scenario

  # validate on user create/update
  with_options if: -> user { ['create', 'update'].include? user.validation_scenario } do |user|
    user.validates_confirmation_of :password
    user.validates_presence_of :password, :on => :before_create
    user.validates_presence_of :email, :password
    user.validates_uniqueness_of :email
    user.validates_format_of :email, :with =>/.+@.+\..+/i
  end

  # validate on resend email cofirmation/reset password
  with_options if: -> user { ['send_email_confirmation', 'reset_password'].include? user.validation_scenario } do |user|
    user.validates_presence_of :email
    user.validates_format_of :email, :with =>/.+@.+\..+/i
  end
  ...

控制器/user_controller.rb

class UsersController < ApplicationController
  def create
    @user = User.new(user_params)
    @user.validation_scenario = 'create'

    respond_to do |format|
      if @user.save
        format.html { redirect_to root_url, notice: 'User was successfully created.' }
      else
        format.html { render action: 'new' }
      end
    end
  end
  def user_params
    params.require(:user).permit(:email, :password, :password_confirmation)
  end
end

【问题讨论】：

user.validation_scenario 是如何设置的？
在控制器动作中（手动）。但我也尝试在测试文件中设置它spec/models/user_spec.rb
你能分享那个代码吗？
如果你想看看它是如何实现的，我可以分享代码，但它与unit tests 没有任何关系。谢谢你，我已经解决了：）（谢谢）我在密码确认后在spec/factories/user.rb 中添加了一个新字段：u.validation_scenario 'create'，它就像一个魅力。
在我看来，您根本没有调用自定义验证。

【解决方案1】：

问题是我没有在任何地方设置validation_scenario。所以现在：

spec/factories/user.rb 看起来像这样：

require 'faker'

FactoryGirl.define do
  factory :user do |u|
    u.email                 { Faker::Internet.email }
    u.password              'password'
    u.password_confirmation 'password'
  end

  factory :create_user, parent: :user do |u|
    u.validation_scenario   'create'
  end
end

和spec/model/user_spec.rb

require 'spec_helper'

describe User do
  it 'has a valid factory' do
    FactoryGirl.create(:create_user).should be_valid
  end
  it 'is invalid with empty email' do
    FactoryGirl.build(:create_user, email: nil).should_not be_valid
  end
  it 'is invalid with empty password' do
    FactoryGirl.build(:create_user, password: nil).should_not be_valid
  end
  it 'is invalid with empty password_confirmation' do
    FactoryGirl.build(:create_user, password: nil).should_not be_valid
  end
end

像魅力一样工作
