RSpec，工厂女孩和水豚：没有保存物品

Question

我有可安装的 Rails 引擎 RSpec:

RSpec.configure do |config|
  config.use_transactional_fixtures = false

  config.before(:suite) do
    DatabaseCleaner.clean_with(:truncation)
  end

  config.before(:each) do |example|
    DatabaseCleaner.strategy= example.metadata[:js] ? :truncation : :transaction
    DatabaseCleaner.start
  end

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

简单工厂：

FactoryGirl.define do
  factory :post, :class => MyEngine::Post do
    title 'title'
  end
end

水豚特征：

require 'spec_helper'

describe 'Post', :type => :feature do
  let(:post) { FactoryGirl.create :post }

  it 'index action should have post' do
    visit posts_path
    expect(page).to have_text(post.title)
  end
end

并且 Post 模型没有任何验证。

但是当我运行测试时，它显示没有创建任何帖子。

还有 ActiveRecord 日志：

INSERT INTO "my_engine_posts" ...
RELEASE SAVEPOINT active_record_1
rollback transaction

Answer 1

这个规范总是会失败。

let in RSpec 是延迟加载。 post 在您引用它之前不会真正创建：

expect(page).to have_text(post.title)

因此您可以使用非延迟加载的 let! 或在访问页面之前参考 post:

require 'spec_helper'

describe 'Post', :type => :feature do
  let(:post) { FactoryGirl.create :post }

  it 'index action should have post' do
    post
    visit posts_path
    expect(page).to have_text(post.title)
  end
end
