1、常见的契约测试工具
Pact
python版本pact-python
Pacto
Sprint Cloud Contract
Pact是最常用的契约测试工具
2、Pact基本工作流程
基于消费者的业务逻辑，生成契约文件
写代码主要写获取Pact文件(图一)的代码
模拟消费者向生产者发请求有相应的工具直接运行
3、Pact-Python安装
进入github官网
https://github.com/pact-foundation/pact-python/
用命令行安装
如果碰到报错
那就是在pact\bin目录下缺少ZIP压缩文件
解决方案：
进如pact包下载官网，找到对应的ZIP包自行下载，放到pact\bin目录下，再重新用命令安装
https://github.com/pact-foundation/pact-ruby-standalone/releases
写一个例子
创建一个生产者和两个消费者
miku.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>消费者 Miku</title> </head> <body> <h1 class = ‘cover-heading‘>{{result[‘name‘]}}</h1> <p class="lead">邮箱：{{result[‘contact‘][‘Email‘]}}</p> <p class="lead">电话：{{result[‘contact‘][‘Phone Number‘]}}</p> </body> </html>
nanoha.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>消费者 Nanoha</title> </head> <body> <h1 class = ‘cover-heading‘>{{result[‘name‘]}}</h1> <p class="lead">邮箱：{{result[‘contact‘][‘Email‘]}}</p> <p class="lead">电话：{{result[‘contact‘][‘Phone Number‘]}}</p> <p class="lead">国家：{{result[‘nationality‘]}}</p> </body> </html>
用flask写一个mock接口
用来当做生产者
api_service.py
#! usr/bin/env python # _*_ coding: utf-8 _*_ from flask import Flask,request,jsonify app = Flask(__name__) app.config[‘JSON_SORT_KEYS‘] = False rsp_body = [ { "salary": 45000, "name": "Hatsune Miku", "nationality":"Japan", "contact": { "Email": "hatsune.miku@woniuxy.com", "Phone Number": "13900110001" } },{ "salary": 80000, "name": "Takamachi Nanoha", "nationality":"Japan", "contact": { "Email": "takamachi.nanoha@woniuxy.com", "Phone Number": "18800880008" } } ] @app.route(‘/information‘,methods=[‘GET‘]) def test(): get_name = request.args.get("name","").lower() if get_name == ‘miku‘: rsp = jsonify(rsp_body[0]) elif get_name == ‘nanoha‘: rsp = jsonify(rsp_body[1]) else: rsp = jsonify({‘status‘: ‘404 not found.‘}) return rsp if __name__ == ‘__main__‘: app.run(host=‘0.0.0.0‘, port=8080)
同样用flask写两个消费者consumer_miku.py 和 consumer_nanoha.py
consumer_miku.py
from flask import Flask,request,jsonify,render_template import urllib3 import json app = Flask(__name__) @app.route(‘/miku‘,methods=[‘GET‘]) def miku_html(): params = {"name": "miku"} http = urllib3.PoolManager() resp = http.request(‘GET‘, ‘http://localhost:8080/information‘, params) result = json.loads(resp.data.decode()) return render_template("miku.html", result = result) if __name__ == ‘__main__‘: app.run(host=‘0.0.0.0‘, port=8081)
consumer_nanoha.py
from flask import Flask,request,jsonify,render_template import urllib3 import json app = Flask(__name__) @app.route(‘/nanoha‘,methods=[‘GET‘]) def nanoha_html(): params = {"name": "nanoha"} http = urllib3.PoolManager() resp = http.request(‘GET‘, ‘http://localhost:8080/information‘, params) result = json.loads(resp.data.decode()) return render_template("nanoha.html", result = result) if __name__ == ‘__main__‘: app.run(host=‘0.0.0.0‘, port=8082)
运行生产者和消费者，然后打开URL
pact-verifier --provider-base-url=http://localhost:8080 --pact-url=consumer_miku-provider.json
1、创建第一个Pact契约测试用例
1>先做一个公共方法
作用：用来实现我们一个发请求的方法
query.py
#! usr/bin/env python # -*- coding: utf-8 -*- import requests def get_cartoon_characters(name): # pact作为模拟生产者时，其端口默认为1234 resp = requests.get(‘http://localhost:1234/information‘,{‘name‘:name}) return resp
我们做契约测试，首先是模拟生产者，‘1234‘是pact默认的端口号
2>写一个契约测试用例
contract.py
#! usr/bin/env python # -*- coding: utf-8 -*- import atexit import unittest from pact import Consumer,Provider from microservice.Contract_test.query import get_cartoon_characters # 构造pact对象，定义消费者服务的名字并给它一个生产者服务 pact = Consumer(‘Consumer Miku‘).has_pact_with(Provider(‘Provider‘)) pact.start_service() # 注册退出的时候关闭pact服务 atexit.register(pact.stop_service) class GetMikuInfoContract(unittest.TestCase): def test_miku(self): # 定义响应期望的结果 expected = { "salary": 45000, "name": "Hatsune Miku", "nationality": "Japan", "contact": { "Email": "hatsune.miku@woniuxy.com", "Phone Number": "13900110001" } } # 定义响应头 headers = { "Content-Type":"application/json" } # 定义模拟生产者提供者接受请求以及响应的方式 (pact .upon_receiving(‘a request for Miku‘) .with_request( method=‘GET‘, path=‘/information‘, query={‘name‘:‘miku‘} ).will_respond_with(200,headers,expected)) # 定义消费者服务向模拟生产者发出请求并活得响应 with pact: result = get_cartoon_characters(‘miku‘) # 做最后的断言 self.assertEqual(result.json(),expected) if __name__ == ‘__main__‘: unittest.main(verbosity=2)
2、运行
1>先运行生成一个契约文件（.json文件）
2>先运行生产者api_service.py
3>打开终端，进入契约脚本目录，运行命令
pact-verifier --provider-base-url=http://localhost:8080 --pact-url=consumer_miku-provider.json
pact-verifier --provider-base-url=http://localhost:8080 --pact-url=consumer_miku-provider.json
测试结果通过，如下图：
