本文介绍了如何在Rails应用中设置RSpec与Cucumber的集成，包括安装所需gem、配置Gemfile以及运行Cucumber和RSpec的基本步骤。确保正确安装gem并配置环境以进行高效的测试和自动化测试。

1. RSpec

2. Unit test

3. DSL: Domain-specific language, examplesso far, migrations, regexes, SQL

4. "should_receive" to mock up a method.

5. 一篇关于RSpec的中文简单介绍： http://ruby-china.org/topics/2848
6. 代码覆盖分析工具SimpleCov: https://github.com/colszowka/simplecov

如何设置Cucumber + RSpec:

group :test, :development do
  gem 'cucumber-rails'
  gem 'cucumber-rails-training-wheels' # some pre-fabbed step definitions  
  gem 'database_cleaner' # to clear Cucumber's test database between runs
  gem 'capybara'         # lets Cucumber pretend to be a web browser
  gem 'launchy'          # a useful debugging aid for user stories
end

Make sure your Gemfile contains the above codes, as well as the line

gem 'rspec-rails'

within the group :test, :development block.

运行

bundle install --without production

来保证gem都安装了。

If necessary, set up the Cucumber directories (under features/) and the RSpec directories (under spec/), allowing overwrite of any existing files, by running the commands：

rails generate cucumber:install capybara

rails generate cucumber_rails_training_wheels:install

rails generate rspec:install

Double-check that everything was installed by running the tasks:

rake spec

rake cucumber

因为features和specs还没写，配置正确的话，以上两条命令应该是正确运行并且提示没有test运行。 RSpec根据版本不同，也有可能提示找不到 '_spec.rb' 文件。
