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

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

install
```
rails generate rspec:install
```
运行测试
```
rake spec
```

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

安装watchr
```
gem 'watchr'
```

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}"  putsendwatch("spec/.*/*_spec.rb") do |match|  run_spec match[0]endwatch("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)

运行
```
watchr .watchr
```
增加spark提升速度
```
gem 'spork', '1.0.0rc3'
```
运行
```
spork --bootstrap
```

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  endendSpork.each_run do  # This code will be run each time you run your specs.end

修改.rspec文件，增加如下代码
```
--drb
```
运行spork
```
spork
```
在运行 watchr .wtachr 速度加快了
清除test环境下的缓存，编辑 config/environments/test.rb
```
config.cache_classes = false
```
