Rspec 使用笔记

打算以后使用rspec 就行测试开发，由于第一次在项目中使用，所以，记录再次，便于以后查询

本文的记录参考了开源软件 angle-nest 和 Ruby-China源码

1.  安装gem
   

   group :development,  :test do
     gem 'cucumber-rails', :require => false
     gem 'database_cleaner'
     gem 'factory_girl'
     gem 'factory_girl_rails'
     gem 'rspec-rails'
     gem 'capybara'
     gem 'delorean'
   end
   

   
   
   
   
2. install
   
   

   rails generate rspec:install

   
   
   
3. 运行测试
   

   rake spec

   
   
4. 修改helper文件
   

     config.mock_with :rspec
     config.use_transactional_fixtures = false
   
     config.include Delorean
   
     DatabaseCleaner.strategy = :truncation
     config.before do
       DatabaseCleaner.clean
     end
   

   
   
5. 安装watchr
   

   gem 'watchr'

   
   
6. 新建.watchr文件
   

   def run_spec(file)
     unless File.exist?(file)
       puts "#{file} does not exist"
       return
     end 
   
     puts "Running #{file}"
     system "bundle exec rspec #{file}"
     puts
   end
   
   watch("spec/.*/*_spec.rb") do |match|
     run_spec match[0]
   end
   
   watch("app/(.*/.*).rb") do |match|
     run_spec %{spec/#{match[1]}_spec.rb}
   end
   

   
   解析
   

       一旦spec/目录下有以_spec.rb结尾的文件发生了改变，watchr便会自动运行run_spec 方法来对该文件进行测试。
       一旦有app/目录下有.rb结尾的文件发生了改变，立即调用run_spec 方法来执行该文件所对应的spec测试文件。
       run_file 通过文件名来检查spec文件是否存在, 然后来运行该spec (调用 system)
   

   
   
   
   
7. 运行
   

   watchr .watchr

   
   
8. 增加spark提升速度
   

   gem 'spork', '1.0.0rc3'

   
   
9. 运行
   

   spork --bootstrap

   
   
10. 修改spec_helper.rb
    第一，上传 rubygems，因为我们已经有bundler了
    修改spec_helper.rb文件如下
    

    require 'spork'
    #uncomment the following line to use spork with the debugger
    #require 'spork/ext/ruby-debug'
    
    Spork.prefork do
      ENV["RAILS_ENV"] ||= 'test'
      require File.expand_path("../../config/environment", __FILE__)
      require 'rspec/rails'
      require 'rspec/autorun'
    
      # Requires supporting ruby files with custom matchers and macros, etc,
      # in spec/support/ and its subdirectories.
      Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}
    
      RSpec.configure do |config|
        config.mock_with :rspec
        config.use_transactional_fixtures = false
        config.include Delorean
    
        DatabaseCleaner.strategy = :truncation
        config.before do 
          DatabaseCleaner.clean
        end
      end
    end
    
    Spork.each_run do
      # This code will be run each time you run your specs.
    
    end

    
    
11. 修改.rspec文件，增加如下代码
    

    --drb

12. 运行spork
    

    spork

    
    
13. 在运行 watchr .wtachr  速度加快了
    
14. 清除test环境下的缓存，编辑 config/environments/test.rb
    

    config.cache_classes = false
