为什么升级到Rails 3.2.1会导致多个Rspec测试失败？

Question

我的测试套件中的所有211规格都正常通过...直到我从rails 3.2升级到rails 3.2.1.现在197我的规格失败了.大多数这些错误都有"错误的参数数量(0表示1)"错误,如下所述.

示例#1:

class DocumentLibrary < ActiveRecord::Base
  extend FriendlyId
  friendly_id :title, :use => :slugged
  has_many :shelves, :dependent => :destroy
  has_many :documents, :through => :shelves
  validates :title, :presence => true, :uniqueness => true

  default_scope :order => :title
end

规格:

  it "can be shown on the company menu" do
    dl = FactoryGirl.create(:document_library, :title => 'Test', :menu => false, :company => true)
    dl.should be_valid
  end

失败:

   1) DocumentLibrary can be shown on the company menu
     Failure/Error: dl = FactoryGirl.create(:document_library, title: 'Test', menu: false, company: true)
     ArgumentError:
       wrong number of arguments (0 for 1)
     # ./spec/models/document_library_spec.rb:6:in `block (2 levels) in <top (required)>'

如果我在FactoryGirl.create行之前调用调试器,我得到:

例#2

class Album < ActiveRecord::Base
  belongs_to :photo_library

  validates :title, :presence => true
  validates :title, :uniqueness => {scope: :photo_library_id}
end

class PhotoLibrary < ActiveRecord::Base
  default_scope :order => :title
  has_many :albums, :dependent => :destroy

  validates :title, :presence => true
  validates :title, :uniqueness => true
end

规格:

  before :each do
    @photo_library = FactoryGirl.create(:photo_library, title: 'Products')
    login_admin
  end

  it "destroys an album" do
    3.times { FactoryGirl.create(:album, photo_library: @photo_library) }
    visit photo_library_path(@photo_library)
    find("h3").click_link 'Delete'
    find("#notice").should have_content("Album deleted successfully")
    Album.count.should eq 2
  end

失败:

1) Albums destroys an album
     Failure/Error: login_admin
     ArgumentError:
       wrong number of arguments (0 for 1)
     # ./app/controllers/sessions_controller.rb:8:in `create'
     # (eval):2:in `click_button'
     # ./spec/requests/albums_spec.rb:7:in `block (2 levels) in <top (required)>'

我的sessions_controller中的第8行是:

user = User.find_by_email(params[:email])

此时检查params显示所有内容(包括:email)都应该存在.

对比例#3

FactoryGirl的这个规范很好:

  it "is unique within a library" do
    pl = FactoryGirl.create(:photo_library, title: 'Products')
    pl2 = FactoryGirl.create(:photo_library, title: 'Competitors')
    a = FactoryGirl.create(:album, title: 'Gold Series', photo_library: pl)
    na = Album.create(photo_library_id: pl.id, title: 'Gold Series')
    na.should_not be_valid
    na.title = 'Cyclone'
    na.should be_valid

    na = Album.create(photo_library_id: pl2.id, title: 'Gold Series')
    na.should be_valid
  end

工厂定义如下:

  factory :document_library do
    sequence(:title) { |n| "Library Title#{n}" }
  end

  factory :photo_library do
    sequence(:title) { |n| "Photo Library Title#{n}" }
  end

  factory :album do
    sequence(:title) {|n| "Album#{n}"}
  end

如果我从DocumentLibrary模型中注释掉FriendlyId行,则示例#1通过.我不知道为什么会有所作为.

但是,有些规格仍未通过.考虑以下模型(不使用FriendlyId)和3.2.1中的漏洞规范:

class DrawingLibrary < ActiveRecord::Base
  validates :title, :presence => true
  default_scope order: :title 
  has_many :drawings, :dependent => :destroy
end

 it "displays in alpha order" do
  FactoryGirl.create(:drawing_library, title: 'C')
  FactoryGirl.create(:drawing_library, title: 'B')
  FactoryGirl.create(:drawing_library, title: 'A')

  ts = ''

  DrawingLibrary.all.each do |draw_lib|
    ts += draw_lib.title
  end

  ts.should eq 'ABC'
end

1) DrawingLibrary displays in alpha order
     Failure/Error: DrawingLibrary.all.each do |draw_lib|
     ArgumentError:
       wrong number of arguments (0 for 1)
     # ./spec/models/drawing_library_spec.rb:19:in `block (2 levels) in <top (required)>'

结果:rspec spec/models/document_library_spec.rb --backtrace

 1) DocumentLibrary can be shown on the company menu
 Failure/Error: dl = FactoryGirl.create(:document_library, title: 'Test', menu: false, company: true)
 ArgumentError:
   wrong number of arguments (0 for 1)
 # ./spec/models/document_library_spec.rb:6:in `block (2 levels) in <top (required)>'

我正在使用rvm和ruby 1.9.3,Rubygems是1.8.16.Factory Girl是2.6.0,factory_girl_rails是1.7.0.rspec-rails是2.8.1.

这是我目前所知道的:

• 降级回Rails 3.2.0会让一切恢复正常
• 升级到Edge Rails并不能解决问题
• rspec gems的运行边缘版本无法解决问题
• 该应用程序在开发模式下正常运行并按预期运行.只有测试似乎受到影响.
• 降级为ruby 1.9.2并不能解决问题
• 升级到ruby 1.9.3-p125并不能解决问题
• 对于测试环境,从MySQL更改为SQLite并不能解决问题
• 将factory_girl_rails降级到1.6.0甚至1.5.0并不能解决问题
• 使用Factory.create(...)而不是Factory(...)不能解决问题
• 使用FactoryGirl.define()和FactoryGirl.create()不能解决问题
• 评论出FriendlyId的内容会使一些规范通过(见下文)
• 运行db:test:prepare(或db:reset,db:migrate)无法解决问题
• 将所有FactoryGirl定义/创建更改为一致不会解决问题
• 在新的rvm gemset下重新安装gem(甚至完全重新安装rvm)并不能解决问题
• 在Test/Unit和FactoryGirl中重写这些测试不会产生任何错误.所以FactoryGirl可能不是问题

任何人都能指出我的方向吗？或提供故障排除建议？

这是我的Gemfile:

source 'http://rubygems.org'

gem 'rails', '3.2.1'

gem 'mysql2'
gem 'dynamic_form'
gem 'friendly_id'

group :assets do
  gem 'sass-rails', "  ~> 3.2.3"
  gem 'coffee-rails', "~> 3.2.1"
  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'
gem 'therubyracer'
gem 'bcrypt-ruby'
gem 'capistrano'
gem "paperclip", :git => "git://github.com/thoughtbot/paperclip.git"

group :test, :development do
  gem 'rspec-rails'
  gem 'launchy'
  gem 'ruby-debug19'
  gem 'database_cleaner'
  gem 'capybara-webkit'
  gem 'spork', '~> 0.9.0.rc'
  gem 'guard-spork'
end

group :development do
  gem 'fuubar'
  gem 'powder'
end

group :test do
  gem 'turn', :require => false
  gem 'capybara'
  gem 'factory_girl_rails'
  gem 'guard-rspec'
end

升级到Rails 3.2.1后,Gemfile.lock的唯一区别在于Rails核心库(没有更改测试宝石).

Answer 1

这可能不是根本原因，但由于您的错误提示 FactoryGirl，我首先将所有工厂（及其创建）转换为另一种（新/推荐（？））语法，即FactoryGirl.define do ...和doclib = FactoryGirl.create(:document_library ...。运行规范时可能会Factory有所不同（与控制台中的情况不同）。
