Ruby on Rails：从 test_unit 切换到 rspec

Ruby on Rails: Switch from test_unit to rspec

提问by Explosion Pills

I'm going through a tutorial that has suggested using rspec, but I have already gone through a lot of default rails installation. I really don't want to have to redo the installation at all. Anyway, when I run

我正在阅读一个建议使用 的教程rspec，但我已经完成了很多默认的 rails 安装。我真的不想重新安装。不管怎样，当我跑

$ rails g integration_test named

I get

我得到

  invoke  test_unit
  create    test/integration/named_test.rb

When I run bundle, various rspecgems are listed, but test_unitis not. The tutorial seems to have rails invoke rspecinstead of test_unitwithout doing anything additional. How do I get rails to use rspecwith the integration test generator command?

当我运行时bundle，rspec会列出各种宝石，但test_unit不是。本教程似乎调用rspec了rails，而不是test_unit没有做任何额外的事情。如何让 railsrspec与集成测试生成器命令一起使用？

In your config/application.rbfile :

在您的config/application.rb文件中：

config.generators do |g|
  g.test_framework :rspec
end

Now when you run your generators (example rails generate scaffold post), you get rspec test files. Remember to restart your server. For more information on generators see:

现在，当您运行生成器（示例rails generate scaffold post）时，您将获得 rspec 测试文件。记得重启你的服务器。有关生成器的更多信息，请参阅：

RailsCasts #216 Generators in Rails 3

RailsCasts #216 Rails 3 中的生成器

If you really want to use the integration_test generator you'll need to specifically modify the command:

如果你真的想使用 integration_test 生成器，你需要专门修改命令：

rails g integration_test named --integration-tool=rspec

Working with Rails 3.2.8and rspec-rails 2.11.4, I discovered that my problem was in my Gemfile. I had rspec-railsin the :testgroup but not the :developmentgroup. Since Rails defaults to running in development mode (including when you're running generate), rspec-railshas to be in your :developmentgroup for it to hook into the generators. Once I had that in place, everything worked fine.

在使用Rails 3.2.8和rspec-rails 2.11.4 时，我发现我的问题出在我的 Gemfile 中。我rspec-rails在:test组中但不在:development组中。由于 Rails 默认在开发模式下运行（包括运行 generate 时），rspec-rails因此必须在您的:development组中才能连接到生成器。一旦我有了它，一切都很好。

As of Rails 3.2.12, follow these steps in order

从 Rails 3.2.12 开始，按顺序执行以下步骤

rails new app_name --skip-test-unit

Add rspec-rails to your Gemfile in the development, test group

将 rspec-rails 添加到开发、测试组中的 Gemfile

group :development, :test do
  gem 'rspec-rails'
end

Run bundle install

跑 bundle install

Run the generator

运行生成器

rails generate rspec:install

... and cleanup your existing test directory:

...并清理您现有的测试目录：

rm -Rf $RAILS_ROOT/test

Came across this issue today. application.rb has to be updated with:

今天遇到这个问题。application.rb 必须更新为：

config.generators do |g|
  g.test_framework :rspec
  g.integration_tool :rspec
end

To use RSpec instead of default Test::Unit, run following command first

要使用 RSpec 而不是默认的 Test::Unit，请先运行以下命令

$ rails generate rspec:install

This command will create following folder/files

此命令将创建以下文件夹/文件

create  .rspec
create  spec
create  spec/spec_helper.rb

Now whenever you used generator to generate rails components like controller, model etc, it will create corresponding RSpecs.

现在，每当您使用生成器生成控制器、模型等 Rails 组件时，它都会创建相应的 RSpec。

In config/application, add this code

在配置/应用程序中，添加此代码

 config.generators do |g|
       g.test_framework  :rspec
       g.integration_tool :rspec
 end

1. when create new rails app, skip TestUnit framework, or it will generate test_unit directory.

1.新建rails app时，跳过TestUnit框架，否则会生成test_unit目录。

$rails new your_app --skip-test-unit

$rails new your_app --skip-test-unit

2. add below code to your_app/config/application.rb file:

2. 将以下代码添加到 your_app/config/application.rb 文件中：

config.generators do |g| g.test_framework :rspec end

config.generators do |g| g.test_framework :rspec end

3. add below code to your_app's Gemfile:

3. 将以下代码添加到 your_app 的 Gemfile 中：

group :test, :development do gem 'rspec-rails' end save it, and run bundle installto install rspec gem

group :test, :development do gem 'rspec-rails' end 保存它，然后运行bundle install以安装 rspec gem

4. Initialize the spec/ directory

4.初始化spec/目录

rails generate rspec:install

rails generate rspec:install

$ rails g model Account
      invoke  active_record
      create    db/migrate/20140205052617_create_accounts.rb
      create    app/models/account.rb
      invoke    test_unit
      create      test/models/account_test.rb
      create      test/fixtures/accounts.yml
$ rails d model Account

Running script/rails generate rspec:installdoes not add rspec as default framework. Added below command in config/application.rb and then it works

运行script/rails generate rspec:install不会将 rspec 添加为默认框架。在 config/application.rb 中添加以下命令，然后它就可以工作了

config.generators do |g|
  g.test_framework :rspec
end
$ rails g model Account
      invoke  active_record
      create    db/migrate/20140205052957_create_accounts.rb
      create    app/models/account.rb
      invoke    rspec
      create      spec/models/account_spec.rb
$ rails -v
Rails 4.0.2

What I found that I did that some of the other methods works still is to check my spelling....I had what @tovodeverett had grouping rspec-rails with :development and :test but spelt development incorrectly. That fixed my issue but I was generating tests with test_unit instead of rspec.

我发现我所做的一些其他方法仍然有效是检查我的拼写....我有@tovodeverett 将 rspec-rails 与 :development 和 :test 分组但拼写错误 development 的内容。这解决了我的问题，但我使用 test_unit 而不是 rspec 生成测试。
