grape api单元测试

推荐两个网址：

https://github.com/rspec/rspec-rails

http://rspec.info/documentation/

上传了一个api的单元测试，https://github.com/shiralwz/grape_api_rspec

主要步骤：

(1)在Gemfile里加入新gem

gem 'rspec-rails', '~> 3.0'

(2)Download and install by running

bundle install

(3)Initialize the spec/ directory (where specs will reside) with

rails generate rspec:install

运行这个命令会自动生成以下三个文件

• .rspec
• spec/spec_helper.rb
• spec/rails_helper.rb

(4)新增单元测试的代码

(5)执行

bundle exec rspec  spec/...

============================

对api的单元测试代码

require 'rails_helper'RSpec.describe "helloAPI",type: :request do  describe "GET the /api/hello" do    it 'should return correct response via GET' do      get '/api/hello', name: 'Mike'      expect(response).to be_success      expect(response).to have_http_status(200)      body = JSON.parse(response.body)      body['message'] == 'Hello Mike via GET'    end   end   describe "POST the /api/hello" do    it 'should return correct response via POST' do      post '/api/hello', name: 'Mike'      expect(response).to be_success      expect(response).to have_http_status(200) //这里由于在api里设置了200所以检测200,默认是201      body = JSON.parse(response.body)      body['message'] == 'Hello Mike via POST'    end   end end
