如何在测试我的应用程序之前自动加载测试数据库中的数据? [英] How to auto-load data in the test database before to test my application?

问题描述

我使用 Ruby on Rails 3.0.9 和 RSpec 2.我想在测试我的应用程序之前自动加载 test 数据库中的种子数据.也就是说，在测试启动时(当我运行测试时)我想自动填充"\自动启动"测试数据库.

I am using Ruby on Rails 3.0.9 and RSpec 2. I would like to auto-load seed data in the test database before I tesst my application. That is, at the testing start up time (when I run tests) I would like to "auto-populate"\"auto-boot" the test database.

如何用种子数据填充数据库?

PS:当我阅读时，(也许)我应该通过向 /spec/spec_helper.rb 文件添加一些代码来填充测试数据库......但是什么代码以及怎么做?

P.S.: As I read around, (maybe) I should populate the test database by adding some code to the /spec/spec_helper.rb file... but what code and how?

在我的 task/custom.rake 文件中，我有:

In my task/custom.rake file I have:

namespace :test do
  desc "Boot database"
  task :boot => [:load, :seed] do
  end

  desc "Reboot database"
  task :reboot => [:purge, :boot] do
  end
end

推荐答案

如果你只想调用种子耙任务，我会这样做:

If you'd like to just invoke the seed rake task, I'd do something like this:

ENV['RAILS_ENV'] = 'test'
Rake::Task["db:seed"].invoke

但是，我建议使用 Fixtures (http://guides.rubyonrails.org/testing.html#the-low-down-on-fixtures).

But, I'd recommend using Fixtures (http://guides.rubyonrails.org/testing.html#the-low-down-on-fixtures).

或者甚至是像 Factory Girl (https://github.com/thoughtbot/factory_girl) 这样的夹具替代品，您可以加载带有所有关联数据的虚拟数据.这是一种不那么脆弱的方法.

Or even better a fixture replacement like Factory Girl (https://github.com/thoughtbot/factory_girl), whereby you can load dummy data with all the associated data. This is a much less brittle approach.
