rails创建项目，部署，测试流程(rails5.0+ruby2.3.1)

rails new test_app --skip-test-unit 不生成默认的test，稍后用rspec
cd test_app

修改Gemfile（大部分为自动生成）

source 'https://ruby.taobao.org' -- 使用淘宝镜像，因为连接不了rubygem

  gem 'rspec-rails', '3.5.1' -- 此处添加最新rspec

  # Use sqlite3 as the database for Active Record

end

group :test do -- 添加capybara及其依赖gem,能够编写类英语交互语句

    gem 'capybara', '2.8.0'
end

gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

bundle install

bundle install --without production
bundle update
bundle install

生成rspec测试模块

rails generate rspec:install

push至git上

git init
git add .
git commit -m "Initial commit"
git remote add origin url
git push -u origin master

设置rails，让其服务于静态资源文件

config/environments/production.rb 

TestApp::Application.configure do
  .
  .
  .
  config.serve_static_assets = true
  .
  .
  .
end

 spec测试文件：

require 'rails_helper'

RSpec.describe "StaticPages", :type => :feature do
  describe "Home page" do
    it "should have the content 'Help'" do
      visit '/static_pages/home'
      expect(page).to have_content('Sample App')
    end
  end

  describe "Help page" do
    it "should have the content 'Help'" do
      visit '/static_pages/help'
      expect(page).to have_content('Help')
    end
 end
end

 测试语句

bundle exec rspec spec/requests/static_pages_spec.rb

 启动rails

rails s
