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

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
