Question

我无法弄清楚我的模型规范（user_spec.rb）中我做错了什么。我正在尝试检查身份验证方法是否使用有效的密码，但我认为规范的User.find_by部分出现问题，因为它返回nil。我已检查它是否响应：authenticate，：password和：password_confirmation，它已通过（为了便于阅读，我将在下面的代码中省略它。）

这是我在运行规范时遇到的失败：

user_spec.rb：

require 'spec_helper'

describe User do

describe "return value of authenticate method" do
  user = FactoryGirl.create(:user)
  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

我也在使用FactoryGirl来生成用户名和电子邮件地址，但我认为这与失败无关：

require 'faker' 

FactoryGirl.define do 
  factory :user do |u| 
    u.fullname { Faker::Name.name } 
    u.email { Faker::Internet.email }
    u.password { "foobar" }
    u.password_confirmation { "foobar" }
  end 
end

问题在于规范的设置方式。你正在使用一个隐含的主题，对于这个规范，它将是User.new。这就是为什么你看到一个具有所有nil属性的User对象。

你的条款应该更像是

it { found_user.authenticate(user.password).should eq user }

和

it { user_for_invalid_password.should be_nil }

实际测试行为。

更新：

随着RSpec 3.x中使用expect语法作为首选语法，现在将是：

it { expect(found_user.authenticate(user.password)).to eq user }

和

it { expect(user_for_invalid_password).to be_nil }

尝试在DB中查找用户时Rspec失败
