# RSpec

# 资料

# 测试

# 添加 RSpec
group :development, :test do
  gem 'sqlite3', '1.3.7'
  gem 'rspec-rails', '2.13.1'
end

# 用于界面交互测试
group :test do
  gem 'selenium-webdriver', '2.0.0'
  gem 'capybara', '2.1.0'
end

# 概念

BDD：行为驱动开发。 TDD：测试优先。失败--实现--通过；遇红，变绿，重构； DSL：Domain-specific Language，领域专属语言。

# 运行

# bundle exec 保证 RSpec 运行在 Gemfil 指定的环境
bundle exec rspec spec/requests/static_pages_spec.rb

自动化测试

# guard-rspec

# Spork 加速测试

# 重构

代码经常会『变味』丑陋、啰嗦、重复。经常重构很重要，一个好的测试就显出其价值了，可降低引入BUG风险。

# 测试用例

require 'spec_helper'

describe "Static pages" do
  # 测试主页是否包含某内容
  describe "Home page" do
    it "should have the content 'Sample App'" do
      visit '/static_pages/home'
      expect(page).to have_content('Sample App')
    end
  end

  # 测试 Titile
    it "should have the title 'About Us'" do
          visit '/static_pages/about'
          expect(page).to have_title("Ruby on Rails Tutorial Sample App | About Us")
    end
end

# 测试代码重构

describe "Home page" do
before { visit root_path }  # 使用before 代替重复的代码
it "should have the content 'Sample App'" do
expect(page).to have_content('Sample App')
end
it "should have the base title" do
expect(page).to have_title("Ruby on Rails Tutorial Sample App")
end
it "should not have a custom page title" do
expect(page).not_to have_title('| Home')
end
end

let 方法，只要指定就会创建一个局部变量，visit/click_link 函数（177页）

RSpec, Capybara, FactoryGirl的使用方法介绍 (opens new window)

# 运行单例

# 可从报错信息中获得这句话
rspec spec/controllers/webapp/resumes_controller_spec.rb

# 针对某块内容的测试，可以预先生成公用数据

 describe 'test get_maturity' do
      before :each do
        @user = create(:user)
        @resume = create(:resume, user_id: @user.id)
        @education_experience = create(:education_experience, user_id: @user.id)
        @expect_job = create(:expect_job, user_id: @user.id)
      end

      it "test maturity = 100" do
        res = Resume.get_maturity @user.id
        expect(res).to eq(100)
      end
    end

# 针对 Model 的测试

# 期待 create 结果不被限制
expect(resume).not_to be_valid
