rails TDD 的好工具 :guard

环境1.9.3 3.2.3, 3.0以下的rails好像不支持

1.  Guardfile

group  :test do
  gem 'guard'
  gem 'guard-rspec'
  gem 'guard-cucumber'
  gem 'guard-livereload'
  gem 'rspec-rails'
  gem 'cucumber-rails'
  gem 'spork'
  gem 'guard-spork'
  gem 'rspec'
  gem 'cucumber'
  gem 'database_cleaner'

  gem 'capybara'
  gem 'webrat'
end

现在cucumber不常用，可以去掉了

group :development ,:test do
  gem 'guard'
  gem 'guard-rspec'
  gem 'guard-livereload'
  gem 'rspec-rails'
  gem 'spork'
  gem 'guard-spork'
  gem 'rspec'
  gem 'database_cleaner'
  gem 'webrat'
end

2. bundle install

3. guard init

4. 

rm -R test 

Guardfile 

guard 'spork', :wait=>60,:cli=>'--drb',
rspec  :cli=>"--color --format nested --fail-fast --drb"
cucumber :cli => '-c --drb --port 1234 --profile guard'

5. 

rails generate cucumber:install
rails generate rspec:install
spork --bootstrap
spork cucumber --bootstrap

6.  rake db:test:prepare

7. http://datacodescotch.blogspot.com/2011/11/warning-cucumber-rails-required-outside.html

undefined method `allow_rescue=' for ActionController::Base:Class (NoMethodError)

gem 'cucumber-rails',require: false 

 8 . 建立项目的时候可以

rails new railtest --skip-test-unit --skip-bundle -d postgresql

 9. 不使用test_unit

appication.rb

config.generators do |g|
   g.test_framework :rspec #=> or whatever
end
