我是编程新手,已经学习了大约 11 周的 Ruby on Rails。
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 ==)
我使用Devise作为我的用户模型,将FactoryGirl用于我的工厂。
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
。这是我的规格
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了。有一段时间,我收到"电子邮件已被占用"错误,我已经过去了。我什至让规范通过一次,但我使用的是现已弃用的"应该是"语法。当我转到正确的":expect"语法时,出现此错误。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
以下是我在 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。为了确保这一点,我做了一个耙子db:migrate和一个耙子db:test:prepare。测试通过。然后我再次做了精确的测试,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

您的email
属性必须是唯一的,并且您不会在测试之间清理数据库,因此您在第二次和后续执行测试时会出现错误。请参阅 https://relishapp.com/rspec/rspec-rails/docs/transactions 以了解在 RSpec 中使用事务。
只是为了打包彼得所说的内容,我能够通过将此设置添加到我的 spec_helper.rb 来解决我的问题。
RSpec.configure do |config|
config.use_transactional_fixtures = true
end
