我是编程新手,已经学习了 Ruby on Rails 大约 11 周。

在尝试测试我的用户工厂进行验证时,我得到

  1) User has a valid factory
Failure/Error: expect(@user.valid?).to eq(true)

expected: true
got: false

(compared using ==)

我在我的用户模型中使用 Devise,在我的工厂中使用 FactoryGirl。

这是我的用户工厂:
FactoryGirl.define do 
factory :user do
name "John Fahey"
sequence(:email, 100) { |n| "person#{n}@example.com" }
password "password"
password_confirmation "password"
confirmed_at Time.now
end
end

...这是我的规范
require 'rails_helper'

describe User do
before do
@user = build(:user)
end

it "has a valid factory" do
expect(@user.valid?).to eq(true)
end
end

我一直在努力让这个规范通过一段时间。有一段时间我收到了“电子邮件已经被占用”的错误,我已经克服了这个错误。我什至让规范通过了一次,但我使用的是现在已弃用的“应该是”语法。当我转到正确的“:expect”语法时,我收到此错误。有没有人知道我在这里做错了什么?

这是我的模型
class User < ActiveRecord::Base

#== schema information.
# create_table "users", force: true do |t|
# t.string "name"
# t.string "email", default: "", null: false
# t.string "encrypted_password", default: "", null: false
# t.string "reset_password_token"
# t.datetime "reset_password_sent_at"
# t.datetime "remember_created_at"
# t.integer "sign_in_count", default: 0, null: false
# t.datetime "current_sign_in_at"
# t.datetime "last_sign_in_at"
# t.string "current_sign_in_ip"
# t.string "last_sign_in_ip"
# t.string "confirmation_token"
# t.datetime "confirmed_at"
# t.datetime "confirmation_sent_at"
# t.string "unconfirmed_email"
# t.datetime "created_at"
# t.datetime "updated_at"
# end

# add_index "users", ["email"], name: "index_users_on_email", unique: true
# add_index "users", ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true


has_one :list
has_many :items, through: :list
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable, :confirmable
end

这是我在 rails 控制台中创建用户实例并测试错误时看到的内容:
2.0.0-p576 :004 > @user = User.create
(0.2ms) begin transaction
(0.2ms) rollback transaction
=> #<User id: nil, name: nil, email: "", encrypted_password: "", reset_password_token: nil, reset_password_sent_at: nil, remember_created_at: nil, sign_in_coun
t: 0, current_sign_in_at: nil, last_sign_in_at: nil, current_sign_in_ip: nil, last_sign_in_ip: nil, confirmation_token: nil, confirmed_at: nil, confirmation_sen
t_at: nil, unconfirmed_email: nil, created_at: nil, updated_at: nil>
2.0.0-p576 :005 > @user.save
(1.0ms) begin transaction
(0.1ms) rollback transaction
=> false
2.0.0-p576 :006 > puts(@user.errors)
#<ActiveModel::Errors:0xa7cff88>
=> nil
2.0.0-p576 :007 >

当我打印错误消息时,我得到
2.0.0-p576 :007 > puts(@user.errors.messages)
{:email=>["can't be blank"], :password=>["can't be blank"]}
=> nil

这里有一些有趣的事情。为了确保,我做了一个 rake db:migrate 和一个 rake db:test:prepare。测试通过了。然后我再次进行了精确测试,它失败了。
vagrant@rails-dev-box:~/code/blocitoff$ rake db:migrate
vagrant@rails-dev-box:~/code/blocitoff$ rake db:migrate
vagrant@rails-dev-box:~/code/blocitoff$ rake db:test:prepare
vagrant@rails-dev-box:~/code/blocitoff$ rspec spec/models/user_spec.rb
#<ActiveModel::Errors:0xbdf0740>
.

Finished in 0.1764 seconds (files took 8.96 seconds to load)
1 example, 0 failures
vagrant@rails-dev-box:~/code/blocitoff$ rspec spec/models/user_spec.rb
#<ActiveModel::Errors:0xa97066c>
F

Failures:

1) User has a valid factory
Failure/Error: expect(@user.valid?).to eq(true)

expected: true
got: false

(compared using ==)

最佳答案

您的 email属性必须是唯一的,并且您没有在测试之间清理数据库,因此在第二次和后续执行测试时会出错。见 https://relishapp.com/rspec/rspec-rails/docs/transactions了解 RSpec 中事务的使用。
