标签: shoulda

我正在使用带有shoulda的Test :: Unit来测试控制器.

因为我只是测试控制器,所以我不希望渲染视图.

我正在对某些对象进行存根,在渲染视图时会抛出一些错误,但测试不会失败,因为控制器是正确的.

那么,从我的测试中,是否有任何方法可以禁用模板/视图的渲染？

我听说rSpec就是这样的.

我正在使用RSpec + Shoulda在Rails 3中测试我的RESTful控制器.我无法弄清楚如何测试创建动作的重定向.标准RESTful控制器应重定向到新帖子的show动作.例如,如果我有一个Project Model的ProjectsController,那么在成功创建后,该操作应该:

redirect_to project_url(@project)

Shoulda提供了一个方便的redirects_to宏来处理这个问题.这是我尝试过的:

describe ProjectsController, '#create' do
  context "Anonymous user" do
    before :each do
      @attrs = Factory.attributes_for(:project_with_image)
      post :create, :project => @attrs
    end
    it { should assign_to(:project) }
    it { should respond_with(:redirect) }
    it { should redirect_to(@project) }
  end
end

(是的,我正在使用FactoryGirl,但因为在这种情况下我只使用它作为属性,所以它应该没关系.我想.)

如何在那里指定最后一次测试？它应该redirect_to(...)什么？我试过@project,project_url(@project)..但我无法理解.

看看Shoulda匹配器代码,我注意到redirect_to匹配器可以接受一个块.但我不确定如何访问该块中新创建的@project对象......

有什么想法吗？

请帮忙:

我想用minitest用户.

这是我得到的例外:

这是我的gemfile:

gem 'minitest'
gem 'minitest-should_syntax'
gem 'miniskirt'
gem 'rack-livereload'
gem 'guard'
gem 'guard-minitest'
gem 'guard-bundler'

gem 'guard-annotate'

gem 'sqlite3', :require => 'sqlite3'

这是我的test_helper:

ENV["RAILS_ENV"] = "test"
require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'
require 'minitest/autorun'
require 'minitest/should_syntax'

class ActionController::TestCase
  include Devise::TestHelpers
end

我有一个带验证的模型,如下所示:

class Order
  include Mongoid::Document

  field :first_name, type: String
  field :last_name, type: String

  validates_presence_of :first_name, :message => "Can't be empty"
  validates_presence_of :last_name, :message => "Can't be empty"
end

我描述模型rspec和思想机器人shoulda:

describe Order do
  # validations
  it { should validate_presence_of(:first_name) }
  it { should presence_of(:last_name) }
end

但是我失败了:

Failures:

  1) Order 
     Failure/Error: it { should validate_presence_of(:first_name) }
       Expected errors to include "can't be blank" when first_name is set to nil, got errors: ["first_name Can't be empty (nil)", …

我正在使用Rails 4＆Devise构建社交网络的课程。

我被困试图通过一门课程，这是我得到的错误：

1) Error:
UserFriendshipsControllerTest#test_: #new when not logged in should get redirected to the login page. :
NoMethodError: undefined method `authenticate!' for nil:NilClass
    test/controllers/user_friendships_controller_test.rb:8:in `block (3 levels) in <class:UserFriendshipsControllerTest>'

这是我的users_friendships_controller_test.rb：

require 'test_helper'

class UserFriendshipsControllerTest < ActionController::TestCase

context "#new" do
    context "when not logged in" do
        should "get redirected to the login page" do
            get :new
            assert_response :redirect
      end
    end
  end
end

我的user_friendship.rb：

class UserFriendship < ActiveRecord::Base
    belongs_to :user
    belongs_to :friend, class_name: "User", foreign_key: "friend_id"

    private

        def friendship_params
            params.require(:user).permit(:user_id, …

我正在使用shoulda和factory_girl开发REST测试.代码如下

 context "on :delete to :destroy" do
    setup do
      @controller = NewsArticlesController.new
      @request = ActionController::TestRequest.new
      @response = ActionController::TestResponse.new

      @news_article =  Factory.create(:news_article)

    end

    should "destroy new NewsArticle" do
      assert_difference('NewsArticle.count', -1) do
        delete :destroy, :id => @news_article.id
      end
    end

    should_redirect_to news_articles_path
  end

结果我看到了

  1) Error:
test: on :delete to :destroy should redirect to index. (NewsArticlesControllerTest):

你能告诉我PLZ - 什么是错的以及我如何修改测试以使它们正常工作？

UPD:路线看起来很好

news_articles …

模型

validates_length_of :description, :maximum => 255, :allow_nil => true

spec_file

it { should ensure_length_of(:description).is_at_most(255).allow_nil }

回归

Failure/Error: it { should ensure_length_of(:description).is_at_most(255).allow_nil }
 NoMethodError:
   undefined method `allow_nil' for #<Shoulda::Matchers::ActiveModel::EnsureLengthOfMatcher:0x0000000acb03e0>

请帮忙!

我正在使用Ruby on Rails 4.2.0和rspec-rails 3.1.0以及应用匹配器2.7.0

当运行测试我有这个错误

Failure/Error: it { should validates_presence_of :name }
     NoMethodError:
       undefined method `validates_presence_of' for #<RSpec::ExampleGroups::Profile::Vaidations:0x00000007881768>
     # ./spec/models/profile_spec.rb:5:in `block (3 levels) in <top (required)>'

这是我的模特

class Profile < ActiveRecord::Base
  belongs_to :user
  accepts_nested_attributes_for :user
  validates :user, presence: true
  validates :username, presence: true, uniqueness: { case_sensitive: false }, length: {maximum: 50}
  validates :name, presence: true, length: {maximum: 50}
  validates :phone, presence: true, uniqueness: { case_sensitive: false }, length: {maximum: 50}
  validates :age, presence: true, …

我正在尝试使用shoulda匹配器进行一些基本的rspec测试,并且我遇到了一个错误,我之前没有看过这个问题.

我有一个名为name的唯一属性,但由于项目所需的原因,我在config/locales/en.yml中覆盖了我自己的消息形式的默认"已经被拍摄"消息,而且似乎不喜欢它.

我收到此错误消息

 Failure/Error: it { should validate_uniqueness_of(:name) }

   Flavor did not properly validate that :name is case-sensitively unique.
     Given an existing Flavor whose :name is ‹"Factory Flavor Namea"›,
     after making a new Flavor and setting its :name to ‹"Factory Flavor
     Namea"› as well, the matcher expected the new Flavor to be invalid and
     to produce the validation error "has already been taken" on :name. The
     record was indeed invalid, but it produced these validation errors
     instead:

     * name: ["This …

使用shoulda和FactoryGirl测试模型验证。

工厂

FactoryGirl.define do
  factory :tag do
    value { Faker::Lorem.word }

    user
  end
end

标签模型

class Tag < ApplicationRecord
  validates :value,
            presence: true,
            uniqueness: { case_sensitive: false }

  belongs_to :user
  has_and_belongs_to_many :cards
end

标签规格

RSpec.describe Tag, type: :model do
  describe 'validations' do
    it { should validate_presence_of(:value) }
    it { should validate_uniqueness_of(:value) }
  end

  describe 'associations' do
    it { should belong_to(:user) }
    # it { should have_and_belong_to_many(:cards) }
  end
end

运行测试时出现以下错误，
