ruby-on-rails – Rails Rspec套件出现故障但是单独运行时它们会

发布时间：2020-12-17 02:07:03 所属栏目：百科来源：网络整理

导读：事实：运行我的整套规范将导致610个规格中的21个一致错误. 如果我运行任何单独的spec文件(例如：messages_controller_spec.rb),它们都将通过. 如果我单独运行任何失败的规格,它们将各自通过. 这些错误主要是ActionMailer失败,但有些错误. 一个令人困惑的方

事实：

>如果我单独运行任何失败的规格,它们将各自通过.

这些错误主要是ActionMailer失败,但有些错误.
一个令人困惑的方面是某些规范失败,因为数据库中有一个额外的行比预期的要多,而其他的则因为行数少于预期而失败.也就是说,如果它是一个清理或缓存问题,它似乎应该是一个或多一个.

我目前通过内联运行Rails 4.1.1,Ruby 2.0.0p451,Rspec 2.14.8,Sidekiq！

Gemfile(用于测试)

group :development,:test do
  gem 'better_errors'
  gem 'binding_of_caller'
  gem 'faker'
  gem 'guard-rspec'
  gem 'pry'
  gem 'rspec-rails'
  gem 'spork-rails'
  gem 'sqlite3'
  gem 'thin'
end

group :test do
  gem 'capybara'
  gem 'capybara-email'
  gem 'capybara-webkit'
  gem 'database_cleaner'
  gem 'fabrication'
  gem 'launchy'
  gem 'selenium-webdriver'
  gem 'shoulda-matchers'
  gem 'webmock'
  gem 'vcr'
end

请注意,我已经检查了大约十二个类似的问题,这些问题无法解决这个问题.所以,澄清一下：

>我没有使用ARGV
>我以前没有使用过(：all) – 我之前使用过:(每个).
>我之前尝试过Rails.cache.clear：套件和套件：每个规格.
>我将数据库清理程序设置为：截断所有清理(更慢,但结果比：事务更好 – 使用：transaction重新加载更新值时出现问题)

为方便起见,也许一些例子会有所帮助：

scheduler_spec.rb(显示运行整个套件时失败的测试)

require 'spec_helper'
require 'rake'
require 'sidekiq/testing'
Sidekiq::Testing.inline!

describe "scheduler",:vcr do
  describe ":wipe_abandoned_images" do
    let!(:abandoned_old_image)   { Fabricate(:image) }
    let!(:abandoned_young_image) { Fabricate(:image) }
    let!(:adopted_image)         { Fabricate(:image) }
    let(:run_cleaner) do
      Rake::Task[:wipe_abandoned_images].reenable
      Rake.application.invoke_task :wipe_abandoned_images
    end

  before do
      abandoned_young_image.update_columns(listing_id: nil,updated_at: 6.days.ago)
      abandoned_old_image.update_columns(  listing_id: nil,updated_at: 9.days.ago)
      Rake.application.rake_require 'tasks/scheduler'
      Rake::Task.define_task(:environment) #Stub env. Rspec runs the App,so dont want Rake to run it again.
  end

  context "for claimed images" do
      it "leaves the image" do
        adopted_image_id = adopted_image.id
        run_cleaner
          expect(Image.all.count                ).to eq(2)
          expect(Image.find(adopted_image_id) ).to be_present
      end
    end
  end
end

请注意,我正在使用Sidekiq的内联！测试先前应用程序的配置,取得了良好的成功.没有这个问题.

forgot_passwords_controller_spec.rb(显示运行整个套件时失败的测试)

require 'spec_helper'
require 'sidekiq/testing'
Sidekiq::Testing.inline!

describe ForgotPasswordsController do
  let!(:jen) { Fabricate(:user,email: 'jen@example.com') }

  describe "POST create" do
    context "with valid email provided" do
      before { post :create,email: 'jen@example.com' }
      after do
        ActionMailer::Base.deliveries.clear
        Sidekiq::Worker.clear_all
      end

      it 'sends the reset email to the users provided email' do
        expect(ActionMailer::Base.deliveries.count).to eq(1)
      end
    end
  end
end

以下以各种方式运行规范时会发生什么：

ForgotPasswordsController规范通过SublimeText2中的RubyTest插件传递

运行整套Rspec时测试失败
如果单独运行或作为spec文件来运行,这些失败将通过.
$rspec

Finished in 49.71 seconds 610 examples,21 failures,10 pending

失败的例子：

有时它有额外的价值

13) scheduler :wipe_abandoned_images for abandoned images under 1
week old leaves the image
Failure/Error: expect(Image.all.count ).to eq(2)

06003

有时它会丢失或不加载值

18) ForgotPasswordsController POST create with valid email provided
sends the reset email to the users provided email
Failure/Error: expect(ActionMailer::Base.deliveries.count).to eq(1)

06004

rspec ./spec/controllers/reset_passwords_controller_spec.rb:73 # ResetPasswordsController POST create with a valid token sends the link with token in the body of the email

解决方法

我无法解释造成错误的真正原因.但这必须归功于全局设置Sidekiq测试模式.从规范的head部分删除Sidekiq设置并尝试以下操作：

before do 
    Sidekiq::Testing.inline! do
      post :create,email: 'jen@example.com' 
     end  
    end
    after do
      ActionMailer::Base.deliveries.clear
      Sidekiq::Worker.clear_all
    end

    it 'sends the reset email to the users provided email' do
      expect(ActionMailer::Base.deliveries.count).to eq(1)
    end
