rspec---单元测试

配置环境

  1. add to Gemfile:
    1
    2
    3
    4
    5
    6
    7
    8
    # Gemfile: 
    gem 'rspec-rails', '~> 3.5.2'
    然后运行：
    $ bundle exec rails generate rspec:install
    记得要把生成的.rspec 文件做个修改，删掉
    # .rspec file:
    --color 
    # NO --warning, --require spec_helper
  1. 下面是测试lib文件的一个例子： make sure your have this:

config/application.rb

config.autoload_paths += %W(#{config.root}/lib)
test a file in lib folder:

require 'rails_helper' # 这句话极度重要. 
require 'html_parser'  # it's not require 'lib/html_parser'
describe HtmlParser do

  it 'should parse html_content' do
    puts 'hihihi'
  end 

end

        }
      }
    OrderDishesLabel.find(@order_dishes_label.id).name.should == new_name
  end
  it 'should delete destroy' do
    size_before_delete = Order_dishes_label.all.size
    delete :destroy, :id => @order_dishes_label.id
    Order_dishes_label.count.should == size_before_delete - 1
  end
end
