rSpec 安装

环境：ruby 1.86 rails 2.34
安装：
1.

gem install rspec

2.一定要记得安这个

gem install rspec-rails

使得以下命令可用：

ruby script/generate rspec_controller
ruby script/generate rspec_model    Organization  name:string desription:string
ruby script/generate rspec_scaffold Organization  name:string desription:string

3、在项目目录下运行

ruby script/generate rspec

将会生成相关的rake，使你的rake spec可用
4、在项目中用以下命令建模

ruby script/generate rspec_controller
ruby script/generate rspec_model    User  name:string email:string
ruby script/generate rspec_scaffold User  name:string email:string

5、写测试代码和模型代码
Organization.rb

 
class Organization < ActiveRecord::Base
  validates_presence_of :name, :message => "name can't be null"
end

Organization_spec.rb

require 'spec_helper'
require 'Organization'

describe Organization do
  before(:each) do
    @name = 'yxyԺ'
    @desc = 'cbyxyԺ'
    @valid_attributes = {
      :name => @name,
      :description => @desc
    }
  end

  it "should create a new instance given valid attributes" do
    o = Organization.create!(@valid_attributes)
    o.name.to_s.should be(@name)
    o.description.to_s.should be(@desc)
  end

  it "should name not be nil " do
    Organization.create.errors.on(:name).should include("name can't be null")
    Organization.create.should raise_error
 end

end

6、用rake进行测试

rake
rake:all
rake:models
rake:views
rake:controller
.....

是运行相应目录下的所有有 _spec.rb文件
7、测试结果

>rake spec:models 
(in D:/Ruby/Apps/fee)
..
