ruby-on-rails - 为什么我的模型的唯一性验证规范在应该通过时却失败了？

Question

我正在学习使用 RSpec 进行测试。我的测试有问题。

我的模型:

class User < ActiveRecord::Base
  has_secure_password

  # Validation macros
  validates_presence_of :name, :email
  validates_uniqueness_of :email, case_sensitive: false
end

我的工厂:

FactoryGirl.define do
  factory :user do
    name "Joe Doe"
    email "joe@example.com"
    password_digest "super_secret_password"
  end
end

还有我的规范:

require 'rails_helper'

RSpec.describe User, type: :model do
  user = FactoryGirl.build(:user)

  it 'has a valid factory' do
    expect(FactoryGirl.build(:user)).to be_valid
  end

  it { is_expected.to respond_to(:name) }
  it { is_expected.to respond_to(:email) }
  it { is_expected.to respond_to(:password) }
  it { is_expected.to respond_to(:password_confirmation) }

  it { expect(user).to validate_presence_of(:name) }
  it { expect(user).to validate_presence_of(:email) }
  it { expect(user).to validate_presence_of(:password) }
  it { expect(user).to validate_uniqueness_of(:email).case_insensitive }
end

我希望这次测试能通过。但我得到的结果是:

Failures:

1) User should validate that :email is case-insensitively unique Failure/Error: it { expect(user).to validate_uniqueness_of(:email).case_insensitive }

   User did not properly validate that :email is case-insensitively unique.
     The record you provided could not be created, as it failed with the
     following validation errors:

     * name: ["can't be blank"]
 # ./spec/models/user_spec.rb:18:in `block (2 levels) in <top (required)>'

Finished in 0.34066 seconds (files took 1.56 seconds to load) 9 examples, 1 failure

Failed examples:

rspec ./spec/models/user_spec.rb:18 # User should validate that :email is case-insensitively unique

我错过了什么？

更新

我认为这是一个错误:https://github.com/thoughtbot/shoulda-matchers/issues/830

Answer 1

这是因为您在 IMO 中声明了 2 次!首先构建用户，然后在 expect() 中构建相同的用户。

只需像这样使用您使用 factory-bot 构建的第一个用户:

it 'has a valid factory' do
    expect(user).to be_valid
end

附言最好使用 Faker gem 而不是像在 factory.rb

中那样使用硬编码实例
