是否可以在“某处"添加“一个`before(:each)`钩子，以便所有spec文件都可以运行它? [英] Is it possible to add "somewhere" a `before(:each)` hook so that all spec file can run it?

问题描述

我正在使用Ruby on Rails 3.2.2和rspec-rails-2.8.1.为了使我的规格文件 DRY (不要重复自己)并播种test数据库，我想为所有那些规格文件运行before(:each)钩子.也就是说，在我所有的规格文件中，我都有以下代码:

I am using Ruby on Rails 3.2.2 and rspec-rails-2.8.1. In order to make my spec files DRY (Don't Repeat Yourself) and to seed the test database I would like to run a before(:each) hook for all those spec files. That is, in all my spec files I have the following code:

describe 'test description' do
  before(:each) do
    load "#{Rails.root}/db/seeds.rb"
  end

  ...
end

是否可以添加before(:each)钩子的某处"，以便所有spec文件都可以运行它? 您有何建议?

Is it possible to add "somewhere" that before(:each) hook so that all spec files can run it? What do you advice?

推荐答案

在spec_helper.rb中:

RSpec.configure do |config|

  #your other config

  config.before(:each) do
    #your code here
  end
end

有很多可用的配置.例如:config.before(:each, :type => [:routing, :controller, :request])

There is much configuration available. For instance: config.before(:each, :type => [:routing, :controller, :request])

您甚至可以创建自己的标签并将代码与之关联:

You can even create your own tags and associate code to it:

config.around :each, unobstrusive: true do |example|
  Capybara.current_driver = :rack_test 
  example.run
  Capybara.current_driver = :selenium
end
