Rspec Test On Rails

  今天，开始为自己的代码补充单元测试，用的是rails 里面的rspec,首先，
1.安装

gem install rspec

2.然后，生成

script/generate rspec_model performances
script/generate rspec_controller performances

:注：如果以前已经用script/generate model ..生成过模型或者控制器的，就选参数n,及不覆盖原来的代码。
3.fixture

 first_performance:
  buskind: 102
  score: 1.0    

4.spec_model

require 'spec_helper'                                                                                                        

describe Performance do
  fixtures :performances

  before(:each) do
    @valid_attributes = { 
      :buskind => 101,
      :score => 1.0 
    }   
  end 

  it "should create a new instance given valid attributes" do
    lambda do  
      Performance.create!(@valid_attributes)
    end.should change(Performance,:count).by(1)
  end 

  it "should be valid" do
    performance = Performance.new @valid_attributes
    performance.should be_valid
  end 
end

5.spec_controller

require 'spec_helper'

describe PerformancesController do
  before(:each) do
    login_as :admin
  end

  it "should save score " do
    lambda do
      xhr :post,:set_performance_score, :performance => {
        :score => 100
      },:id => performances(:first_performance)
    end
    response.should be_success                                                                                               
  end
end                                                                                                                      

6.运行spec测试

spec spec/models/performance_spec.rb
spec spec/controllers/performances_controller.rb

7.另外可以通过tail -f log/test.log查看测试过程信息
