对象被创建。 （RoR，数据库清洁工，工厂女孩）

Question

我是 Rails 的初学者，帮帮我，我不明白问题是什么。好像之前写了别的东西（：每个）...... 以及如何在 test_spac.rb 中编写一个没有创建 Card 对象的测试。 before(:each) 方法不适用于此测试。

这是工作：

test_spec.rb：

require 'rails_helper'

describe "Index Page" do

  before(:each) do
    @card = FactoryGirl.create(:card)
    DatabaseCleaner.start
  end

  it "shows error messages if translation is wrong" do
    visit root_path
    fill_in 'translated_text', with: 'wqww'
    click_on 'Проверить'
    expect(page).to have_content('Неверно!')
  end

  after(:each) do
    DatabaseCleaner.clean
  end

end

rails_helper.rb：

# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require 'spec_helper'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'capybara/rspec'
require 'capybara/poltergeist'
require 'database_cleaner'
Capybara.javascript_driver = :poltergeist
Capybara.default_driver = :poltergeist


Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }

ActiveRecord::Migration.maintain_test_schema!

RSpec.configure do |config|

  config.fixture_path = "#{::Rails.root}/spec/fixtures"

  config.use_transactional_fixtures = false

  config.before(:each) do
    DatabaseCleaner.strategy = :transaction
    DatabaseCleaner.clean_with(:truncation)
  end

  config.before(:each, type: :features) do
    DatabaseCleaner.strategy = :truncation
  end

  config.infer_spec_type_from_file_location!
end

这是行不通的：

test_spec.rb：

require 'rails_helper'

describe "Index Page" do

  before(:each) do
    @card = FactoryGirl.create(:card)
  end

  it "shows error messages if translation is wrong" do
    visit root_path
    fill_in 'translated_text', with: 'wqww'
    click_on 'Проверить'
    expect(page).to have_content('Неверно!')
  end

end

rails_helper.rb：

config.use_transactional_fixtures = false

  config.before(:each) do
    DatabaseCleaner.strategy = :transaction
    DatabaseCleaner.clean_with(:truncation)
  end

  config.before(:each, type: :features) do
    DatabaseCleaner.strategy = :truncation
  end

  config.before(:each) do
        DatabaseCleaner.start
      end

  config.after(:each) do
        DatabaseCleaner.clean
      end

Answer 1

问题解决了：

我做这个：（test_spec.rb） 需要'rails_helper'

describe "Index Page" do

  it "check behavior then translation is wrong" do
    FactoryGirl.create(:card) #################
    visit root_path
    fill_in 'translated_text', with: 'some text'
    click_on 'Проверить'
    expect(page).to have_content('Неверно!')
  end


  it "check page then object is not created" do
    visit root_path
    expect(page).to have_content('Непросмотренных')
  end

end

你能发布你所说的不工作的意思吗？您是否收到任何错误消息？

顺便问一下，你为什么禁用config.use_transactional_fixtures？如果你坚持使用before(:each) 钩子，RSpec 将使用reset the database for you，你不需要使用DatabaseCleaner。
